So, a quick timeline of events to bring everyone up to speed.
Assembled a brand new system on 10/13/2008, system config is as follows...
Corsair 750w PSU
Asus Rampage Formula Motherboard
Intel Core 2 Quad Q9550 Processor
4g of Corsair DOMINATOR 1066 RAM
Sapphire HD Radeon 4870
LG 22x DVD/RW
Western Digital Velociraptor 150g HDD
Seagate 640g HDD
Sony 3.5" floppy
Windows Vista Ultimate (64bit)
System worked perfectly up until 12/27/2008, when while watching a movie the screen flickered several times, and then went complete black for a few moments, grinding my system to a halt. Upon trying to reboot, I would get as far as the windows loading screen and then would lose the image completely. No signal was reaching my monitor. I switched the monitor cable to the secondary DVI port, still nothing. I could hear windows booting up normally, so I chose to start the system in safe mode.
I uninstalled and re-installed the latest ATI drivers and rebooted. Again, no image. Deleting the drivers entirely allowed me to start the system up normally, with an image getting to my monitor, but installing drivers resulted in no image at all. After disconnecting all unnecessary peripherals and performing a complete reformat and re-install of my OS to my primary drive, the problem was still there.
My initial guess was a GPU problem, so I RMA'd the card back and purchased an Asus EAH4870 DK/512 card, which I received on 02/02/2009. The system started up perfectly, with a crystal clear image. It worked fine until 02/13/2009, when the same event occured, only this time while clicking "Yes" to a one of Vista's program permission dialogues. I've performed all the same steps I did previously, and to no avail, even going so far as to switch the card to the second PCI-E slot, where the card wasn't even recognized.
Has anyone else encountered a problem like this, or have any ideas what might be causing it?
