Intel DG31PR motherboard,
1GB powercolor HD 6670 GPU,
Corsair CX 430W PSU,
windows 7 32bit.
Recently upgraded my PC with a new GPU HD 6670 from my old 8400GS. After upgrade i faced boot problems. The computer wont cold boot so initially i thought the drivers are causing the problem so i formatted my PC and installed windows again. The GPU was working fine until i installed the catalyst driver, after reboot the same boot problem continues. I had to remove the GPU for now.
I doubt the faulty card problem because i played Battlefield Bad company 2 and several games when it worked fine. Any suggestions on what the problem might be and any solutions? Help me!
