My computer just shutdown during a night, couple of days ago and would not start up again, no post, just fans were spinning and hdd and power lights came on. So I took out my PCIe graphic card and connected my lcd to on board video and pc would keep restarting no post again. So i got new ram put it in and on windows 7 welcome screen My PC would restart and keep restarting in an infinite loop. Then I tried to re-install my Win but PC would restart on completion and keep restarting in infinite loop, then I entered safe mode during windows installation and disabled my video driver and windows completed installation, but after re-enabling drivers it would restart again on welcome screen. I tried re-installing several drivers from my mobo manufacturer and flashing BIOS but to no succes. Any help would be welcome. Motherboard is G31 -M7 TE
