Gfx Card prob Radeon 9600

Hey.. i'm having trouble with my Connect 3D radeon 9600 pro..

I had it working great for weeks, but lately installed a prog that caused my drivers to roll back (i think anyway). Now the card is unpredictable.. sometimes when i restart, my onboard chipset kicks in and my card isnt detected, then on other occasions i start my computer and it's all good.. card working.

I have removed the sis chipset software and drivers, so there is no reason for them to take control of graphics output and i have my radeon catalyst drivers fully up-to-date. I have also updated the AGP slot drivers (as instructed by radeon manual).

Any solution would be greatly appreciated.

Thanks,

Dave.
