I'm running a Geforce4 Mx440 8x VIVO on a AMD XP1600+ with 768 Mb of sdram, and when i'm running in windows Xp it boots okay but when i'm on the desktop " bang! " My monitor goes in stanby mode. I tied it in a win2k pro environment and no problems... Can somebody help ? Cost me a lot for noting if it's not Xp compatible....
