Hello,
Recently I purchased a Sparkle GeForce 8400GS PCI card (no express PCI just regular old PCI, because I didn't have any other open slots). Here is the rather uninformative amazon product page (http://www.amazon.com/gp/product/B001HA91NY/ref=oh_o06_s00_i00_details).
I bought the card so that I could use 3 monitors running at the same time. Unfortunately whenever I plug in my 3rd monitor to the new card I get these strange white horizontal lines (see picture) and then it usually just freezes after a minute or so. If I try starting the computer with just the new video card and not my other PCI E card it will get as far as the loading screen and then go blank. It isn't the monitor causing the problem because I can plug the monitor into my older working video card and it works fine.
I have seen people discuss either overheating or not having a large enough PSU. It doesn't seem to me like the video card would be overheating so quickly.
I have a 500 watt PSU which I think should be enough to power it, or at least I don't think adding a PCI video card would push it over the edge (maybe I'm wrong?)
Does anyone have any idea what the problem could be?
Thanks a lot.
