Hello guys, i'm having a serious trouble with my pc. I installed windows 7 ultimate x64, and when i try to update the driver of the onboard video my pc starts rebooting, i tried every drivers. I can't install windows 8, when it's finishing the installation my pc starts rebooting too, i think it's because windows 8 has a newer driver than windows 7 and makes my pc reboot. My pc just run if i use the driver windows installs, and i can't play anything. I tried updating BIOS, installing others OS. My pc configuration:
Intel Pentium G2030 3.0GHZ
HD 320 GB 2.5'' Samsung 5400 RPM
Kingston 4GB 1333 MHZ (kvr13n9s8/4) (it's compatible, my friend has an identical pc)
Corsair CX-430
Cougar Spike
My pc is new, i bought it last week. Please, any help?
