Thank you everyone for the help. I will test my powersupply this weekend and see if it's putting out the right voltages. I have the combined one. My volt meter is a bit of a junker though. I'll have to come up with a better one. Any ideas on a decent cheap one? I have an 8800GTS coming today so that should stress the PSU a decent amount. I was also thinking about picking up an eVGA 680i board this weekend from Fry's and seeing how well that works. I do run Vista on my machine though and I've heard of some people having problems with that board and Vista playing nice.

I was also thinking it may be a memory problem, but I've tried many combinations of 6 different sticks and it still wont post with even 1 brand new stick anymore. But I will still run Memtest at stock and see what it finds.
