[other_os] Weird Pixels on Screen Problem

http://ubuntuforums.org – I have a weird problem that I was hoping to run by you guys to see what you think. A few days ago I started getting random red pixels all over my Ubuntu screen (by all over I mean in random locations but there aren't that many of them). They come and go, and are pretty unpredictable, but often stick around for a while, or even blink. Since I was using VMware Workstation 7 at the time for some school labs, I thought that might be causing the problem, but since then, I have had the same problem occur in Windows 7 as well, which points to a hardware problem since 2 completely different Operating Systems are both effected. The weird thing is that the random red pixels all disappear when I do things like open firefox (but come back when I minimize or close it), and when I move my mouse over them the mouse goes overtop of the pixels. If it was a monitor problem I'm pretty sure the red pixels would be overtop of everything. I can also take a screenshot of my desktop and capture them in the image. This points to a software problem. Since the first occurrence, I pulled out my video card (8800GT), and placed it into a nearby PCI-E slot (a different one than the one it was in). I thought if there was a bad connections somewhere that might fix it. This caused Windows 7 to revert back to something like 800x600 resolution, so I also completely reinstalled my nvidia driver to the newest version. The problem still occurs. I also checked my video card's temperature (with Everest) to see if it was overheating. It was about 60 degrees idle which seems ok. I tried running Modern Warfare 2 to see if it would have problems, and there were lots of red pixels during loading screens, but none in game that I noticed and the game seemed to run fine. I'm no expert but I'm guessing it's something that's interfearing with video rendering in such a way as to make the Operating Systems think that is what the screen should look like. Sounds like something is wrong with my video card/motherboard... (Hardware)
