First and foremost, full system specs as its for a friend, not my computer.
i7 950 [email protected] 3.8GHz
12GB (3x4GB) DDR3 @1600MHz
Gigabyte X58A-UD3R
1kW PSU Cougar CMX
3 x EVGA GTX 570 HD 1.25Gb GDDR5
2x 128GB SSD (RAID0)
3x 1TB HDD (no raid) (WD green, WD Black, Seagate barracuda)
Now for the problem
Upon power, the machine posts and gets as far as the windows logo after which the monitors go black saying no signal and the system hangs until a forced reset.
The troubleshooting that has been done so far
Tried every card individually with one monitor, same issue no changes
Tried every stick of ram individually in all slots, same issue
Cleared CMOS returned all settings to stock, same issue
Underclocked the cpu, no changes, same issue
Removed all hard drives except primary raid setup, no change
Fresh install of windows (SSDs formatted):
-computer worked and ran off the vga default drivers. after installing the nvidia drivers the computer would boot and work normal for about 15 minutes after which the system would hang in the same manner and never boot again with the same issue.
-works fine in safe mode though
Computer works fine with a different graphics card (some workstation ATI card), however these 570s have yet to be tested in a different rig.
Suspect is the data path from video cards to cpu. perhaps chipset issue? Anyone have any ideas what could be happening here or any other troubleshooting tips that could shed some light on it? Motherboard or vga problem?
