I've been running my 9700 pro for ages now without a problem. I've just upgraded my motherboard to a Gigabyte 8S655FX.

My problem is this; at fairly regular intervals, my screen changes colours - anything that should be black turns blue (this can be different shades of blue), even when the pc is not under any load. The only way I've found to fix this quickly, is to go into the ATI control panel, click the color tab, and the second I do that, normal service resumes - sometimes only for a few seconds, sometimes the problem won't reappear until the next reboot.

I have a 2 monitor set up, and it generally only happens on the monitor on the VGA port rather than the DV port, although after some testing, running a monitor on just the DV port, I temporarily encountered the same problem.

I've tried different versions of the drivers, and I've removed all other PCI cards. Any ideas what may be causing the problem?

your monitor sounds like it has had its day..buy a new one..

I've got 2 monitors - one is less than a year old and the other is maybe 2 years old - and I've tried it with both. It always happens to the one on the VGA port, unless I am using a single monitor on the DV port, in which case it can happen with either monitor.
