Why computer freezes

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.

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

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

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

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

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

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

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

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

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

Best tool to desolder Laptop DC Jack

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.

I am making a new diagnostic device for desktop computers

It will help me to diagnose the motherboard, the CPU and the PSU (power supply unit). It consists of a few voltmeters and a few ammeters. I will measure the CPU Vcore, the voltage that reaches CPU step down converter and the current that is going to the CPU step down converter.

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

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

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

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.
