    Strange Graphics Card Problem

    I have this stange problem with my PNY GF6800GT. In my computer, I get this garbled screen, but in another PC, it works fine. Another gfx card (a FX5200) works fine in my PC. I really can't figure out if it's the card, my motherboard or otherwise.

    Any ideas?

    Images of what I get:

    Thanks.

    Does it work with a different monitor? Have you tried ajusting the monitor settings?

    Have you been overclocking the card at all?

    No, tried another monitor, same thing. Monitor settings don't affect the image at all. The OSD of the monitor is not scrambled, and seems to work.

    No, it's not overclocked. Never has been.

    Am trying to think where I have seen that problem before, all I can think of is when my 6800GT wasn't sitting in the AGP slot correctly (silly me forgot to put the screw in)

    The graphic corruption only occured as windows attempted to go from the black boot screen to the blue welcome screen, it was like a wierd texture crawl that ended up with a screen looking like yours does.

    Only other thing I can think of that causes a similar display problem is faulty RAM, but I could be wrong.

    Well, I don't think it's the RAM, 'coz it works fine with another card.

    It could be sitting incorrectly in the slot, becuase the card seems to work fine in another PC, but if I re-seat the card, it can sometimes work for a minute before going again.

    I'm pretty much committed to buying replacement hardware now, but if I can sell any of the current hardware, it'll help recover the costs a bit.
