I have a system i just built as follows it has a GA-X58A-UD7 mobo with an i7 950 processor with 2 Nvidia 560ti vidio cards and a windows 7 OS with a corsair 120g SSD ...everything was working fine till i started playing wow. Was on wow a couple of hours and started getting a few horizontal lines across the screen then in a few seconds the screen was covered with the lines by the time i logged out i could barely see the screen then it went to a flickering blue screen and I can't do anything with it.......anyone know what might cause this??

Download the latest graphic driver here:

This will probably fix your problem.

Good luck.

I would try the following:

1) Switch to a different monitor...your current one may be dying.

2) Plug into a different video port (either second port on current card or ports on second card)

3) Remove one graphics card, disable SLI and try both video ports.

4) Try step 3 with second graphics card.

5) If you can, try plugging in another HDD to boot from.

Basically, remove components one at a time to try and reveal which one is messed up. I would even try taking out RAM. A last ditch hope is to reset CMOS by removing the battery (circular, mobo manual will show you where it is located) OR reinstall Windows.

Best of luck!

Either bad RAM, overheated CPU, or a bad (or overheated) video card will cause this. Usually it's bad RAM.

I'm assuming you're running Windows 7. To test RAM with windows 7:

•Click the Windows 7 Start button, type memory, and click on Windows Memory Diagnostic

•Windows will restart and report any errors to you
Method 2: From Windows 7 Control Panel
•Click the Windows 7 Start button.

Method 3: From Windows 7 Command Prompt
•Click the Windows 7 Start button.
•Type cmd in the Start Menu's search box.
•Right-click cmd.exe in the search results and then select Run as administrator.
