ATI Radeon 9800 pro "weird problem"?
I just bought a new computer off of ebay. Everything was apparently in working order, but when I booted up the system the Window's XP logo, while it went through the loading process, had some small boxes in it, and the loading border had small brown spaces on it. However, everything on the desktop looked fine until I tried playing the Unreal Tournament 2004 demo. The video before the game loaded had small black boxes across the entire screen, then everything was ok until actually getting into the game. When the game loaded there were the same small boxes across the entire screen. This was only the beginning, I decided to try to reboot the computer, but this nothing worked correctly, the entire screen was totally messed up and if I physically moved the computer at all, the colors would change on the screen, or the patterns on the screen would change also. Originally I thought it might be a bad monitor, so I tried it on several other monitors with the same result. Sometimes when I turned on the computer the monitor would turn on, and the switch off after a few seconds with nothing appearing on screen, and then just turning off and on until eventually a garbled picture appeared. Next I tested Radeon 7000 64mb PCI graphics card and everything worked perfectly. So I'm assuming it's either the ATI Radeon 9800 pro 128mb, or the agp slot in the mother board which is a MSI 865PE Neo-2. I'm just wondering if anyone has any other ideas for what I could try to get this bad boy working? I tried everything I could think of, making sure everything was securely in place(I found when the screen wouldn't turn on at all if I applied pressure to the video card a picture might appear, but it would still be garbled. Any help would be greatly appreciated.
