I recently installed a Radeon 9800pro 128mb card into my brothers computer. He is running 2.4 ghz p4, 1 gig of RAM, and a 60gb hard drive. The card works fine when i pop it in running at a resolution of 640x480. After I install the drivers and try to bump the resolution up to 800x600 or 1024x768 the monitor goes blank then eventually falls into standby mode (the light on the monitor goes orange). I have tried 3 different 17" CRT monitors. Same thing happens on all of them so it must be the video card. Any suggestions or solutions would be great. -- Thanks
