I have been troubled by this problem since the first day I assembled my computer.

When I play games, the screen may randomly freeze for several seconds. Sometimes come with mashed pictures.

Fisrtly I thought it was my graphic card's problem. However, after I changed my card to the current one, the problem still exists. Then I changed my PSU to the current one, still has the same problem. I even updated my raid0 HDD system to SSD. I tried everything I could only exepet changing CPU and Motherboard. :(

I found that when the problem comes out, it is accompanied by a frequency reduce on my graphic card. The frequency could suddenly decent from 900mhz to 405mhz and it is fixed there unless I restart my computer. It looks like a self-protection function is activated, but I did not overlock anything. Also the temprature of the graphic card is prettey normal. Now I am totally confused. Could it be the motherboard's problem? Anyone can help me figer it out where the problems locate?

Any suggestion would be appretiate! Thanks!

Ensure you have the latest motherboard bios.
Ensure you have a clean installation of the latest graphics drivers.
It does sound like a bad VRAM or overheating issue. Investigate the GPU temps properly.

I think a 560w psu might be a bit too low.

That's my first thoughts, because I wouldn't encounter that problem when I used the integrated graphic in I5-2500K.

Then I updated my PSU. Now the 12v 5v 3v etc. votages are pretty nice and stable. The Seasonic xseries 560W is quite powerful, it even doesn't need to start its fan for cooling when it works. (It is designed like that, not a malfunction:))

Ensure you have the latest motherboard bios ---Yes i did update it and cleaned the cmos manually.

Ensure you have a clean installation of the latest graphics drivers. ---Yes I updated my driver several times, and every time I chose the clean installation.

It does sound like a bad VRAM or overheating issue. ---Yes, I considered that. And I replaced my previous MSI GTX 460 Cyclone by EVGA GTX 560 ti. It is really hard to imagine that both graghic cards have bad VRAM:confused:

Also, I checked my GPU temps, it is keeping around 70℃ when I play the games. It is not too high I think.

But I will try to re-install my driver again, thank you for your suggestions!:)
