From: "Steve W" <steve> Date: Sat, 6 Jan 2007 17:44:About 6 weeks after installing a Gigabyte 6800GS (PCIE) video card onto my ASUS P4V800DX mobo I started to get an intermittent failure. On boot up, the black BIOS splash screen is streaked with white horizontal lines, making the bios screens difficult but not impossible to read. I have upto date licenced XPSP2 on the machine and that starts up but again the screen is corrupted, always to bad to be usable but legible enough to see Windows has started without error. Starting in safe mode has the same corruption to the image. I swapped the card out for an older AGP card I had to hand and that worked fine. But then so did the 6800GS when I put that back in the system. then after a couple of days same thing again. Next time I simply reset the machine during the BIOS startup a couple of time and the fault went away. I was about to send the 6800GS back to the supplier, but googling around seems to suggest this could be a mobo issue. (sending the card back gets a test charge and two way carriage charges if no fault found) Any thoughts on how to nail the source of the problem? BTW the Mobo came from one supplier and the 6800GS from another. Other than this, the set up works great.
Config of machine is 450W power supply DVD reader DVD Writer 250G SATA Audigy 2ZS SoundBlaster 1GB Corsair XMS RAM Intel 2.6GHz processor
