Ok this has me pretty confused, so I am hoping someone here could shed light on this for me.
Over the course of the last 2 months, lines have begun to appear on my secondary monitor. They are in groups of 4 short lines (maybe about 2" long each) and cause artifacts to appear on anything I drag over the area - for instance if I am web browsing, and drag the white part of the browser over it, it leaves it yellow).
Normally I would simply attribute this to the card being fried, but here is the odd thing: This only occurs on my secondary monitor. My primary monitor is fine. When I initially boot the computer, the BIOS screen and the bootup windows screen does not have the glitch. When I switch monitors from Primary to secondary, the secondary monitor still has the lines on it, no matter which physical monitor is secondary. I have tried using the VGA cable as well to verify it wasn't a cabling issue, same thing with that.
I have checked the temp on the card, it is well below the throttle threshold, and I dusted it off with some compressed air and reseated the card, same thing. My power output from the PSU appears fine.
I have tried several sets of drivers, thinking that maybe it was a driver issue, but they all have the same symptoms. Here's the weird part though - when I uninstall the drivers completely, reboot into regular VGA mode, the lines are gone! At this point though, the secondary monitor is in clone mode. I have tried several revisions of the Nvidia drivers, they all do the same thing.
In the past when I have seen artifacts on a card, it didn't have these symptoms. Anybody have an idea on this? P.S. I have not been able to try the card in another computer, as this is the only computer I have with a PCI express x16 slot, and I currently don't own any other PCI x16 cards (only AGP) to test it out with. I also do not have a floppy drive on this computer, so flashing the BIOS on the card would be difficult, although I can dig one up if need be. I cannot seem to find any BIOS online, however, for the geforce 7800GTX series.

Thanks for the advice, looks like I'll be on the market for a new video card soon.
