Reply #30: Certainly will. No luck yet, though.

It's not the monitor, monitor power or data cables, as I've switched those to no effect. So it's something inside the case.

I've reseated all the cards, cleaned out the dust, and ensured all the fans are operating and temps are controlled. Not effect.

It's also not a heat build up thing, as it happens when the machine starts up cold as well as after it's warmed.

A search on the web for similar problems gave some indication that it "might" be a power problem. I'm not sure if that would be the cases power supply or some kind of issue within the video card itself. (Some articles mentioned issues with a video booster?) Moot point, as I don't have a spare vid card nor power supply to do a swap with.

And while I've got a decent electrical tester, I'm embarrassed to admit that I'm not all that versed on how to use it to check out the cases power supply, and I've NO idea what to check on the video card. If anybody has the know-how and wants to give me step by step instructions I'd give that a whirl?

My guess is that it's the video card, something within where it converts the memory cache into a video signal. That would explain why a screen capture doesn't capture the effect. And Nvidia based graphics is something both of our systems have in common. It would be easy enough to check, as a card equivelent to mine is probably like $20 today. But money is a bit tight at the moment, so I'll just put up with the streaks for a while.
