My problem is that when I play, for some time, video games; my screen freezes with small square around the screen and I'm forced to reboot. After some research on the net I updated my graphics card driver, flashed my bios, tested my ram with memtest, checked the temperatures of component (RAS).
I do not know what to do.
For info my config:
CPU: Intel Dual Core E8600 3.33GHz
2gb ram Corsair
ATI Radeon HD 4870
Motherboard: ASUS P5Q3 Deluxe
If someone have a solution then please help me.
