CPU: Intel i7 2600k
Motherboard: MSI P67A-GD55 (B3)
GPU: Asus Nvidia Geforce ENGTX480 1.5 GB
RAM: 2x4GB Geil DDR3 PC3-12800C9 1600MHz
Storage: 3 Samsung 1TB HDD's, two in RAID-1 (storage), OCZ Vertex 60gb SSD (Operating system)
PSU: Corsair TX 950W
Basically, I got all these parts in early 2011 and assembled them fine, and the PC worked perfectly well for 3 weeks. Then one day I was playing a game and the PC crashed, and thereafter would not boot to windows properly, hanging and restarting after the splash screen. It would boot to safe mode fine, and also to full windows if the Nvidia display drivers were uninstalled, but upon reinstalling them it would fail to boot. Doesn't matter what version of the drivers. Updated the BIOS too, no luck. Reinstalled windows, no luck.
I RMA'd the graphics card and it was returned to me with no faults detected. The motherboard was also RMA'd and replaced due to an unrelated issue with the SATA ports. The whole shebang was taken to two tech support places but neither could figure it out (I need to find the notes they gave me...). After a few months of this I was rather fed up and so I put the graphics card from my old PC (Geforce 8800 GTX) into the new one instead, and it works fine. The GTX480 has been sitting in its packaging for a year.
Recently though with Arma 3 being released I got to thinking, I'm sure I can get the GTX480 working. Same old problem, although now instead of crashing on boot, windows 7 seems to boot fine, just with a blank screen (the monitor detects no output and turns itself off), because judging by the Event Viewer the boot continues as normal, and putting MP3 files in the Startup folder, they play all the way to the end. Ubuntu fails to boot at all though. I'm typing this in Windows 7 without the graphics drivers installed.
I'm thinking it might be a PSU issue but I don't have one spare to test with. If anyone knows anything I can try to get this apparently A-ok graphics card working I'd be grateful.
EDIT: oh yes, and it BSoD's when I run Nvidia Monitor (to try and underclock it to reduce power usage to that of the 8800GTX, to see if that would help), system service exemption, BCCode 3b. See second post
