Losing Signal on Monitor


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???

I have had problems with the Omega drivers - I use Catalyst 4.7 with my Radeon 9500.
You could try going back to the Catalyst 3.5 drivers...

Also you could try disabling fast writes in your bios....  <--- Actually I would try this... it will probably work.
Catalyst 3.5 is a bit drastic, isn't it?  I know 4.3 and 4.7 is stable.

How strong is your power supply?  I would have replaced it, instead of trading a 9800 XT for a 9700 Pro.  Even now, if you have a working video card, it should not fade nor be intermittent.  I know Dell uses proprietary supplies, but you can replace them if you get an adapter:

I didn't pay for either Video Card and all I really want is to upgrade my graphics from 64mb to 128mb so me being me I didn't buy a new Power Supply. I have made all the adjustments I can make to my Bios but the problem persisted, I think my self that Drivers may be the problem, I was using the Omega 2567 drivers. Which ones do you recommend???
