Vista freezing

I just recently built a new computer. I have vista home premium. Vista is constantly freezing, or getting a blue screen. It runs fine for a while then freezes or blue screen. The problem report says that it is possible that it is caused by my CPU, Ram, motherboard, or PSU. How do i go about finding out the true cause of this problem. All 4 of those a brand new, and are compatible with each other. I have installed new drivers for each that has drivers. please help.

I have the Asus PN5-E SlI motherboard, core2duo 6400, corsair ram, corsair psu, and pny 7950 gt. i talked to some guy who said the voltage on the ram might be too low. think that could be a cause?

I just changed the voltage from auto to the setting the website says. I will do the memory test after i find my cd burning program. Hopefully this will get fixed soon. I'll let you know what the test says.

Memory is fine. memory is set manually. Vista reinstalled... did not install the nforce memory controller update... seems to be ok so far, (been 30 minutes)

I used to get Blue Screens all the time. I did a clean reinstallation, and now everything is cool (for 1 week; though the last times I had problems after 1 day, so i think I'm in the clear now). All I changed was setting everything in BIOS (memory timings and stuff) before installing. I don't know why it worked, but it did.

I don't know if you've tried it or not but Vista comes with a VERY comprehensive memory test suite - it located my bad bits, I later confirmed with with an overnight run of memtest86 (low voltage, bios setting was too conservative).

I don't think its fair to blame memory issues on Vista - it may actively use more of your memory for caching; much more than XP ever did, but I think that's probably a good thing as my files load a lot faster. After a small adjustment in the first week after installing Vista, I never had another bsod (if you don't count that one bad ATI driver - but that's a different story).
