nvidia 9800 GX2 Full Screen issues
Computer: Dell XPS 410 (purchased around July 2007).
Specs: XPS 410 Product Details | Dell
Motherboard Specs: Documentation
I recently purchased an nvidia 9800 gx2. I'm replacing an 8600 gts.
My drivers and BIOS are up to date. I also upgraded my PSU from the stock 375w to a 530w Raidmax.
When I have the new card (the 9800) in, I experience issues with full screen video. There is stuttering, and the audio goes crazy. This happens for streaming video on Hulu/YouTube, and in VLC/WMP. In VLC, I go fullscreen, it fails until I stop moving the mouse and the navigation bar fades away. At that point, playback is fine, but as soon as I move the mouse, the issues return.
I've tried nearly everything I can think of, including swapping in the old card (video works fine), and swapping in an identical 9800 that I ordered for my roommate at the same time I got mine (same video issues), using a variety of older drivers just in case, and most recently a complete reinstall of Windows 7. I also tried changing various SLI settings in the nvidia control panel, with no luck.
I would think the card itself is not likely to be the issue (since the roommate's card fails in my system, but works in his own), but something about the card is not agreeing with the rest of the system. On the other hand, I just wiped the OS completely, and am still having issues.
One other thing: Upon installing the OS, Windows thought that I had the most recent drivers (after a few restarts), but they were quite a bit out of date. Again, updating these had no effect.
Thanks in advance!
