Ok, I'm gonna try to keep this short, but it's rather convoluted, so I'm probably not going to be all that successful.
First, some history of my hardware upgrades....
Few months ago I upgraded my mobo/cpu to an Athlon 64 X2 3800+ and I went with an ASRock Dual board that has both AGP and PCIe slots so I could continue to use my 9800Pro card until I had the money to upgrade that as well.
Couple weeks ago, I bought the 21" Gateway Widescreen LCD and and a 7800GT video card (XFX model if it matters). Now the problem...
The two symptoms: Occasionally, I'll get graphic streaks through the display, a single line of pixels will flash garbage intermittently, not any specific line of the display.
The second symptom is the display will just go blank for a second, then come back.
Now, when do these symptoms occur? Sometimes never at all. If I don't start seeing them within the first 10-15 minutes of starting the computer, I'll be able to use it for hours on end with no problem. If I do start seeing them, they'll happen regularly until I reboot the PC, and then they'll go away.
Playing games or watching movies appears to make it more likely to happen.
Last week I brought a 1280x1024 LCD display home from work, used it all week without seeing any problems at all. That would indicate it's possibly the Gateway monitor. Friday, I dropped my old 9800 Pro back into the system with the Gateway monitor, and went all weekend without seeing any problems either. Pop the 7800GT back in tonight and I start getting flaky display within minutes of powering up. Reboot the computer and it's all fine again.
I'm simply at a loss as to what is causing this problem. I don't even know what to try out now, other than to just start returning items until it finally goes away. I'd rather not just do that willy nilly though. WTH is going on with my computer?
