How To Make a Computer

2012-01-08T10:49:00.000-08:00

First thing first is necessary to get the motherboard. The motherboard can be a new one or second hand from a source like ebay. Every motherboard is fixed to the case with a few screws so a screw driver is necessary also. All motherboards have screws in the same place so what matters is the size of the motherboard. Usually big motherboard do not fit in mini ATX cases.

Second step is to get the case. There are so many cases styles awailable that it should suid everybodys taste.

Depending on the motherboards type now we chose CPU. It is not hard to chose from because in the market dominates two players so depending on the motherboard it will be Intel or AMD. For games recommended to chose AMD. And for everything else Intel.

In case the CPU is chosen then the motherboard needs to be chosen for that CPU.
Motherboards are manufactured different for each CPU.
Also differs and the CPU by the connetro type. Both the motherboard and the CPU must havethe same CPU slot type say LGA 775.

IMAGE

After the CPU and motherboard are in our possession the next step is to get some RAM. Memory differs in type. Latest now is DDR3. The oldr ones DDR2 and DDR1 are obsolete. They also are not compatible so better is to buy the right one. But this should’t be a problem as sellers always will tell what type RAM it is.

After we have all components mentioned abowe lets start to build. The motherboard fits in the case and is screwed with a few screws. Sometimes we need to screw in a few crews that motherboard will sit on

IMAGE

But sometimes we don’t need to do this as the metal surface has special bumps that the motherboard will lie on.

IMAGE

Now let’s connect all the button and LED cables. Depending from the case there will be a few types of connectors. Sometimes they come as one big plug but usually they are separate plugs for each LED Power LED, HDD LED, RESET, POWER.

IMAGE

On the motherboard usually are markings that show where to connect each plug. Sometimes it is marked with letters sometimes is just a color . Black usually is for POWER Button.

IMAGE

When we connect them lets place the CPU and heatsink.

IMAGE

RAM also is necessary to boot for the first time. Without a RAM there will be no image on monitor. Now we need to connect VGA cable, mouse cable and keyboard cable and boot the computer for the first time.

Boot is normal

VIDEO

It shows that the bootable media not found as there is no hard drive installed.

Installing the hard drive. This computer part can be with SATA or ATA interface. Now ATA is obsolete. It is fitted to the case with a four screws. To fit hard drive properly sometimes necessary to open both sides of the case.

IMAGE

Hard drive is connected to the motherboard with caqbles and another cable is for power.

#Installing DVD drive. Also like hard drive it is fittedto the case with a four screws but screws are different

IMAGE of hard drive and DVD drive screws

It is also connected to the motherboard with SATA cable and it gets power from the power supply through power cable.

If the computer not starting check the memory. Sometimes memory modules ar faulty. But this is very rare.
Another cause that can stop from booting is the power supply. But sldo this is very rare as new power supplies are almost always good.
Of cource the third suspected component would be the motherboard. But never been seen that a new motherboard will not work. But this does not mean that it will never happen. Can occur physical damage or something like that.

When everything is connected and the installation should begin. The OS installation is very straight forward and it almost does mot need further explanation.

How To Replace USB Broken Port On The Laptop

When Windows XP freezes

2012-01-03T01:26:00.000-08:00

If something freezes like a computer or a laptop then experienced computer technicians use General Troubleshooting Theory. This theory needs something about ten pages to explain properly. We will describe here so called Systematic Fault Isolation that is a part of General Troubleshooting Theory. Systematic Fault isolation can help to diagnose issues related to Windows XP freezing.
Systematic Fault Isolation is a technique for systematically isolating the source of an issue. Simply eliminating half of the items that cause the problem or eliminate one after another until the system will be stable.

For example if the Windows XP freezes and the hard drive more than three years old then simply by testing the hard drive or ve will eliminate this component as a cause of the fault or we will know that the hard drive is faulty.
Why to begin with hardware test. Simply because there is no logical point to for example reinstall the operating system if the hard drive has a bad sector or even overheating. It simply will fail again in a while.

Another component that can cause system freezes is memory or RAM. It is not so frequent as hard dirve faults, but when RAM is faulty the system will freeze up or display a blue screen and the shuts down. And now memory issues are more frequent as the capacity of the memory increases so increases the probability to fail.

After we checked the two main components on the computer then we can return to the operating system and check it for viruses, malware and other foreign code pieces in it.
Usually the infected system is reinstalled as we do not want the virus to resurrect. We never found an antivirus that can remove properly the virus code. There is so many viruses and they made so smart . If the virus is reported as mild or low danger then probably the re-installation is unnecessary. But if it has something like Conficker then the re-installation is the best solution.

Another cause could be a power supply, motherboard or the CPU. The CPU usually gets damaged if it overheats. It happens frequently in laptops with a clogged heatsing or radiator plates. In laptops there is almost always some dust covering the heatsink plates near the fan. If the layer of the dust is thick the CPU gets hot and can fail.
Also the motherboard is the cause of fail or freeze. It can happen not so frequent as hard drive fault or RAM fault but still we need to consider it as a component for isolation. ON some brands motherboards the faulty capacitors are cause often of system instability. It is easily found as the capacitors gets deformed or even some color liquid shows up.

This is almost all the possible causes that can cause the computer with Windows XP to freeze. Just remember the hardware the age is critical as the longer it operates the more chances to fail. For the software this may be not the case except may be viruses that gather in the system.

Why computer freezes

2011-12-30T12:31:00.000-08:00

The answer to this question depends on many factors. The computer freezing cause can be software relate or hardware related.
Software related freezes can be caused by a virus, a incompatible drivers, or even operating system design errors but this is very rare.
Other part is a hardware caused freezes. This can be from memory faults, hard disk faults to overheating the CPU etc.
To say what is wrong with the PC straight away is almost impossible. To find the freezing cause best way is to use fault isolation. This is universal method and used by many engineers in PC and Mac worlds.
The main principle is to perform a test or isolate a part of hardware and perform a test. Then if the fault still ezsist we perform second test or isolating the hardware. As test example would be memory so called RAM test. As example we can take the DVD drive from the laptop and then see how it works. We had once a freezing laptop which was with a faulty DVD drive. After the replacement everything worked perfectly.

If the computer freezes completely and even the cursor does not move the best way to start is to test the memory. We seen some of cases when such a total system freeze was caused by faulty laptop memory. Faulty memory or RAM is very rare but it happens from time to time and we cant overlook it.
To test the memory the best software available out there is Memtest. It is a bootable CD. It needs simply to be downloaded to the working system then burned to the CD and then booted on the freezing system.
If this test will show some message in red then congratulations you just found the cause of computer freeze.

If the computer is slow and freezes sometimes but the cursor still can be moved then very high probability that the hard drive is faulty. In other words the information from the hard drive is read is different than it was written.
Especially this is frequent for hard drives that are over three years old. There is a special software to test the hard drive HDTune. Better is to take the hard drive out connect it to the another computer and test it.
If the bad sector will show up as shown in the image below the freezing causing fault has been found.

IMAGE

If the RAM and the hard drive are ok then this probably is caused by operating system. Also if this is a laptop needs to be checked for overheating. Usually overheating is caused by the dust that clogs the heat sink.

If the freezing still happens after the re-installation then probably the CPU or the motherboard are faulty.

Recovering data from broken usb dongle.doc

2011-12-18T07:35:00.000-08:00

The pen drive is the standard usb interface with added to ita small memory chip. All usb pen drives are made by the same principle that thecommunication is based on usb signals.

When we brake the usb dongle usually the crack occurs whenthe metal plug is connected to the PCB inside the device. The inside structureof this device is similar and varies just the how manufacturer implements thewiering or in other words the tracks on the PCB.

In every drive we will find the two tracks that are in themiddle of the plug. They are data + and data – tracks. The other two are poweras +5 V and the ground.

To repair the broken we just need to connct again the brokentracks together and copy the data as soon as possible. The drive after we dothis would not be usable just because the wires can broke again best is just tobin it.

Here is the image that show the internal structure of thepen drive.

We need to connect together wery small four wires that areon the so called PCB (printed cirquit board). Ia am doing it with very smallsoldering iron. And this is not so easy to do so if you do it first better isto practice this on something else.

You will need also a flux and tip dip to clean the solderingiron tip. Also the solder is necessary.

To better understand what to connect here is more imagesshowing the connections.

Best tool to desolder Laptop DC Jack

2011-08-26T12:37:00.000-07:00

Is Hakko 808. I recently have purchased the Hakko 808 desoldering Tool. Straight from the box it done what it suppose to do th DC Jack was desoldered in about 50 seconds and just fell out. What a strange feeling that I never experienced before.

By the way it comes with a 1.0 mm nozzle. I think the 1.6 mm nozzle is also necessary to buy as many laptop DC Jack pins are square form and sometimes the nozzle do not cover the pin.

Everything else just works perfectly.

What amazes me now that back then she was also so naïve and stupid to put people in such a scam. And even more she managed to develop 20 something websites that she was selling something through affiliate links. I just can’t imagine what junk she sold to the public. Probably even some of medications or more dangerous stuff but who cares. Does she care about it.

During the last few days I have found out how to bring a hard disk with bad sectors to normal functionality

2011-06-29T14:44:00.000-07:00

The idea is to squize one partition between bad sectors and include aeria with bad sectors to separate partition that later will be hidden.

Think first before you buy Furious Gold

2011-06-25T03:47:00.000-07:00

Think first before you buy Furious Gold. Yes and do it three times for the best results. Why. They do not support anymore HTC new phones, are arrogant, unfriendly, unhelpful. This is my opinion and I can back it with evidence with what they are writing on forums. Resellers also are the same type. When I bought FG that guy did not activate it for two weeks. Why. Because he waited until he can get away with my money and I can't fill complain about it and get my money back. May be he can play like this but I think he will hit somebody that lives near him and will be visited by smiling faces.

Repairing Samsung NC10 netbook

2011-05-29T03:40:00.001-07:00

I had for couple of days a not working net-book from Samsung. The fault was that it was not able to start Windows. This is a fault I never saw before. As always I decided to strip everything down and leave only the LCD screen and tested it with Ultimate Boot CD for Windows. And it booted to Windows perfectly. The cause that prevented it to start Windows was a wireless card.
Simply removing it fixed the problem. I think there is faulty part that prevents wireless card to work correctly as I tried a few wireless cards and they not worked.
Also I re-flashed the BIOS with the latest version from Samsung web site.

How to use UBCD is explained here.

Finally I have at home a Mac laptop. Would say that the experience is interesting. Frustrating because everything is in different place than in Windows and exciting because how good it looks. Windows now looks like came from stone age.

It is just unbelievable how stupid ...

2010-10-06T11:42:00.000-07:00

It is just unbelievable how stupid people sometimes thinking and thinking that others are just idiots. I bought a Mac on ebay the other day and the seller do not want to send it to me because he is still on a contract with this laptop. Seriously, I do not feel good when people doing this.

By the way, if somebody wants to repair a laptop I can do it in London, UK. Feel better when I do good things...:) My site is here remusnet

I am very pleased to have so dreamed about Mac Book. I bought it from ebay with some adventures. The seller she in my opinion turned out to be completely computer impaired and listed the laptop not correctly. Thats why this laptop is with Mac OS 10.4 but not 10.5 as advertised.
But I will buy Mac OS 10.6 Snow Leopard. This OS I need for my ACMT Apple Certified Mac Technician.
Will post a few pics of it on my remusnet.com site.

To whom SEO is important

2010-08-29T13:57:00.000-07:00

Today I had a flash in my mind about site positioning in search engines. I think Google engineers got pretty smart how to determine site relevance to the keywords typed in.
For example, lets look at a web site ibm.com (lenovo.com). What do you think. Will it be relevant to the typed in keyword IBM. Will it be relevant to typed in keyword laptop computer. Yes of course. Now answer my question how to tell google that this is the site that must rank high for keywords IBM and laptop computer. Let's back engineer it. This site is old and has a content about laptop computer for a long time. There are many links to this site with anchor text laptop computer. It has downloadable drivers, manuals etc. The site has many internal links. The site provides support and site has something to offer like laptop computers.
This is the answer why it is ranking high for keywords IBM and laptop computer.

Improving my room

Getting ready for CompTia exams

2010-08-21T09:51:00.001-07:00

Today is the Friday and I am reading the book CompTia A+ certification second time. Now it
is easier to understand everything as part of information is already remembered. What I
still hardly remember is LCD monitor resolutions, fiber optic cable types, backup types and
which one touches archive attribute. For example there is fiber optic connectors square SC and round connector ST. Why they are named like this have no idea. And what is MT-RJ connector which is for full-duplex connections.
I though that in fiber optic must be used a laser but it turns out that in reality most of fiber optic uses LED ? and runs in multimode.
And there is two fiber optic standards 1000BaseSX and 10GBaseSR.

CompTia exam next Friday

2010-08-21T09:50:00.000-07:00

I have decided yesterday to take CompTia Essentials exam one week later. I do not remember lot of necessary information for example about LCD screen resolutions :). Another cause
would be that when I checked the web site for exam booking there was no exams available at

Friday. So I will be prepared for next Friday.
Have made a interesting page how to increase wireless network coverage and get rid of annoying drops. Check it at remusnet.com It is worth to try because it will help all your devices iPods, iPhones, iPads, wifi enabled mobile phones get better wireless signal.

Two days left until my Comptia A+ essential exam

2010-08-18T12:15:00.000-07:00

I feel little overwhelmed. This is because a lot of information needs to remember and another interesting thing is about exams practice software on the computer. I have a book CompTia A+ Certification exam guide. With this book comes a DVD with a software to practice on the computer. Sadly may be because it is a demo soft all questions are repeating if you try to practice on it second time.

Plans to get CompTia A+ certification

2010-08-17T12:43:00.000-07:00

I am planning to get CompTia A+ certification. Would like to take the first exam on Friday the 20 th Aug 2010. The book I have to get ready for this exam is crazy long 1200 pages. Everybody who have read this book will confirm that this is really book worth the money spent and may be even more. Good for me that about 50 percent information for me is not new but some parts are really hard.

Still keeping eyes on remusnet.com and will publish unedited content because have no other choice. Hope good visual information will take focus from my horrible English :)

I will test my persistence or I hate SEO

2010-08-16T12:49:00.000-07:00

Ok. Let's say search engines like incoming links. Then if I can get a link every days and do it for a year or so. Then it would be approx 365 links to the website per one year. Would be links counted as good links and will it increase website rankings.

Recently I have watched a few videos related to google webmaster tools. The presenter did talk lot about black hat and white hat techniques. He mentioned that google treys to cut off the content generated by black hat techniques using webmasters and let white hat technic sites rank better. So where they left business people who concentrates on business and don't have the time to play SEO games.

Still do not have any success with remusnet.com

2010-08-16T09:33:00.000-07:00

It is strange for me that my site does not get visitors from search engines. It has good information with pictures. There is also complete guides how to perform various computer diagnostics. I have seen websites full of affiliate links and adsense ads ranking well. Why it is like this. I just want to have my business on-line and in real world. I think it is too hard to compete against crazy site optimizations and folks from India generating gazillions of Internet pages.

The Linux Ubuntu installation is pretty straightforward. Presently, the entire Ubuntu 9.04 distribution is compiled into just one installation CD. To get the Ubuntu ISO file, simply follow this link. To install Ubuntu from a CD, you will simply need to burn the downloaded ISO file onto a CD. After that, you need to set your computer to boot from a CD drive and let it boot. This is the first screen that you will see.

You can now select the language for the setup that you prefer.

Now, you have a menu that gives you 5 different choices. The first choice is to boot Ubuntu from the disk without installation. This will leave the hard disk untouched. The second choice is to install Ubuntu on the computer. The third choice is to check the hard disk for errors. It is recommended to perform this check because it takes care of any possible bad sectors on your disk. The fourth choice will be to test the memory or RAM. The fifth choice would be to boot as usual from the hard disk.

Now let us choose to install Ubuntu.

I inspected the power adapter and green light was flashing. I checked resistance of power socket of laptop which was showing just about 5 ohms. This was my first though that there is a short circuit somewhere inside the board.

As you can see I have soldered out the power socket and some components. The main fault was short cirquit between two layers near power socket. By the way this PCB is with 4 layers. I stripped down a part of first layer and in the picture you can see a second layer.

How to Fix a Computer

2010-07-04T05:24:00.000-07:00

In this guide, we shall go in a step-by-step manner about how to fix a computer. This guide is almost the same as another one we have, expect that here we will cover the hardware of the desktop computer in more detail. The other article speaks briefly about both the software and hardware aspects of your computer.

The best way to fix your computer is to test it and then retest it until you have found out what’s wrong with it. There are various testing tools available on the Internet for free download. Whatever tool you use, you will need a step-by-step guide to use it correctly.

You must begin by testing the memory. After a lot of computer repair jobs, I would recommend that you start here. By testing memory, you will test not only the memory but also the processor and partially the motherboard even. It is because in this memory testing process, different components of the motherboard are involved.
Recommended software for memory test is Memtest.

If you own a computer, you will find that knowing to fix it saves you a lot of time and money. Now, if your computer is running slow, it is easier to find where the fault is. Mostly, it lies in the antivirus program that’s involved. Users have reported that the Norton Antivirus demands a lot of power from your computer system. There are several other similar antivirus and antispyware programs that can slow your system down.

Another cause could be that there is a virus or two on your system itself. This leads you to a cycle of problems—to remove the virus, you will need to install an antivirus program but a bulky antivirus application could also slow your computer down.

A faulty hard drive could also be making your computer run slow. If your hard drive is faulty, it might contain one or more bad sectors in it which the computer cannot read or write into. As these sections tend to spread, soon more of your hard disk is likely to be damaged and have areas from where you cannot properly read data. On account of that, the computer functions slower.

We explain here how you can test the hard disk in your computer.

There might be other troubles inside your computer, mostly hardware causes. Hardware components of desktops are definitely different from those in laptops. Even if one of these components develops a fault, your computer might not start at all. You will commonly find faults with PCI cards and TV tuner cards. The DVD drive is also a common problem area. These devices tend to develop faults in their laser systems after you have been using them for a particular length of time. The initial symptom of such a fault is that your devices fail to read the DVDs and CDs. Sometimes, they may not even be recognized at all. If any such thing starts happening, it is time to check the drive itself or the cables going to the drive.

Another cause for the fault may be the presence of faulty drivers. That can be easily rectified by getting the latest drivers from the manufacturer of the hardware.
