You will need
- - memory;
- - screwdriver.
To test the memory modules individually, you need to discover the one that works correctly. Once the module is found, it needs to be reinstalled in another slot of RAM and recheck again. So how can it be a variant of the failure of the memory module and slot connection on the motherboard of the computer.
Quite often in bars RAM simply oxidized contacts. This prevents its normal operation. To solve, turn off the computer, disconnect it also from the power supply. Remove the cover from the system unit. Locate the slot in which you inserted the problematic module. Programs that test the operation of RAM indicate which slot module is connected. If, for example, the slot number "1", then you need to look at the motherboard the first slot.
Now slide the latches of the memory module in the lower position. Pull the bar memory. Take a rag, a little alcohol and wipe the contacts with a connection on the module of RAM. Insert the memory back. Do not close the computer case. Turn your PC on. Test of memory. If errors are detected, then you can close the system unit.
If the memory is malfunctioning, perhaps from its strap just came off some small detail. If so, it should be close. If you have managed to locate the item, review it carefully. The element is conditional a number of letters and digits. Remove the memory. Look on the bar element with this notation. Now just solder the part to the strap. To fly off maybe a capacitor or a fuse. If you have never dealt with a soldering iron, it is better to consult a specialist. After the item is soldered, insert the memory and check her work.
Also there are situations when broken chips on the module. However fix them at home is impossible. If neither the first nor the second case is not helped, then maybe it happened. In this case it is better to carry the memory of the service center.
Advice 2: How to check RAM for errors
Blue screen of death" in Windows operating system and a critical error BSOD often occur due to a problem with the RAM of the computer, its operational memory. That indicates malfunction of the RAM strips and how to test the RAM for errors?
You will need
- program Memtest.
To start is to understand whether there are faults in the RAM. Damaged RAM generates errors with the key word “memory”. If your PC freezes or restarts on a blue screen – feel free to check the RAM.
Checking RAM for errors is carried out by specialized avtozavodaskaya, that is, these programs not needed to run Windows, so you can not worry – the next RAM fails during verification will not occur and the program will last until the final conclusion.
For RAM testing is typically used Memtest program (Memtest 86, Memtest 86+). Usually this means enough to know the bar with the error and what the error or fault in it.
The Memtest program can be downloaded from the official website – www.memtest86.com. The program Packed in an ISO image that you want to install to a blank CD, and then by rebooting the computer, in the BIOS you need to set the first boot component in the drive. The program will then load, and you can start to diagnose the RAM. At the end of diagnostic (and the time depends on the amount of RAM) the program displays a report on the computer screen.
Also in the latest Microsoft operating systems such as Windows Vista and Windows 7, there are built-in and quite powerful tool checking the RAM for errors. It's called Windows Memory Diagnostic. When you start the computer press "F8" and you will see a menu "advanced boot options". Select "Troubleshooting Windows", and on the new screen – under "Tools" by pressing "Enter", select "Windows memory Diagnostic".
