Not while loading or in the post screen.sometimes it happens as soon as win7 starts, after the 'wellcome' message.
I have to do a hard reset so it gets to work again.that happens on win 7. I install win7 with no problems, and the pc works fine.but as soon as i install the VIDEO DRIVER for the intergated graphic on the cpu, at random it shows extreme artifacts then freezes. Thank you beforehand because i know u will help me with my problem.i have core i3 2120 with gigabyte ga h61m ds2.
