I recently exchanged an ATI Radeon 9800 XT for 9700 pro because I could not get the XT working with my Power Supply. I installed the 9700 and everything was working fine but now and again my Monitor loses its signal and the only way I can fix the problem is to log on in Safe Mode and uninstall the Omega drivers ( Radlinker/MultiRes ) and re-install them again. This wasn't so bad as it was Intermittent but now it's getting worse so I removed the card and went back to my Nvidia 64mb GeForce 2. Any Ideas what could be causing the problem. I have a Dell Dimension 4100, 512 mb SDram, 290gb Hard Drive space and a 1GHz Processor with an Intel Motherboard 815 chipset. Any Ideas???
