I have exactly the same problem, and have a similar setup except i'm not overclocking anything yet, I want to get my system running 100% (including 3D Mark progs) before i overclock. I'm fairly sure the problem is the ram, mine is not that great, but seeing that you have TwinMos and yet are still having the same problem, maybe it's not (the Corsair ram in my sig is on order, will be here on Tuesday/Wednesday so i'll let you know if that helped when it gets here). I can't help but notice that we're using the same video card, and on the occasions when i actually get an error message instead of a blank screen, windows is pointing it's finger at the Radeon 9500 Pro. Checking the Event Viewer, i find that there was indeed a problem.

I'm trying to get some answers from ATI if the Radeon is indeed the cause of the problem, i'll keep you posted on my progress and would appreciate if you could share any progress you make.
