The flags you recommended did not make a difference.
If GPU-Z is running when I start guiminer then there's a lockup. It doesn't matter what comes first, CCC/GPU-Z or poclbm, but they can't seem to coexist.
Also, just like this guy here:

...the computer also hangs immediately when I start to play a video (say, youtube).
No OC whatsoever. PSU is 1500 watts, and the 6990's 12v inputs are hooked up to separate PSU ports. I can load the CPU with a benchmark while mining and there are no issues, so it's most likely not a wattage problem.
Topic: Vista x64, Radeon 6990, locks up (Read 1043 times)
what about if you load up GPU-Z first and then try guiminer?
Try -v -w256 -f60 (whats the point of having f higher than 60?)
How many watt power supply? (assuming no OC going on?)

Ok this is strange:
When I have load on the card (poclbm) and I try to open Catalyst Control Center or GPU-Z to check the temps, the computer locks up hard. When there's no load, I can open CCC or GPU-Z no problem. Poclbm alone doesn't cause problems, the computer is mining happily at 650+ mhash (-f 140).
Anyone run into this?
Using latest versions of everything (Catalyst 11.6, etc) on Vista x64.
Not being able to check the temps is a tad annoying.
