Win 7 64 bit
Mobo: Gigabyte GA-X58A-UD3R
RAM: 6GB Corsair 1600 PCA 12800 (3x2)
HDD: WD Caviar Black 1TB
GPU: XFX Radeon HD 5850
New build. Everything was fine. Shut down system for 8 hours. Now, won't boot. Can't even boot in safe mode. Blue screen: "Crucial thread" etc. Repair doesn't work (Does it require internet connection, BTW?) When I try to boot in Safe Mode, when it lists the windows files loading, they all say windows32\driver\ etc. Is this normal, since I installed Win7 64 bit? What do I do now? chkdsk from command prompt? Re-install Windows? If so, what do I do with the Windows.old file? Help!
