I'll let others comment but that 650W power supply sure sounds small for what your running.

I find that PP runs perfectly stable on Windows 7. I've never performed any special tweaks other than turning off Windows Search.
Update. I just performed a seagate diagnostics test on the momentus xt main hard drive and it failed. Not really sure how much of a factor this played on PPcs5 crashing every 20 minutes but i'll let you know after I install the new one. As far as the power supply goes, if anyone thinks this is underpowering this system which is causing this CS5 to freeze up, then I'll go first thing to buy a higher power supply. Comp USA guys (tech mechanics) were telling me that it was fine.
I had this problem with a new X79 system using a Gigabyte GA-X79-UD5 motherboard. Updating the BIOS to the latest available solved this. It was a bug in the BIOS microcode. Do you have the latest BIOS from Asus?
I just installed the newest version bios version 0906 crossing my fingers. My version was pretty old. Let you know after a day to see if it works. Thanks.
I know it is not even the same board manufacturer, but it is the same chipset, and maybe basically the same BIOS.
SUCCESS!!!!!! Alan, you are the MAN!!!! My bios was pretty old. Went to the Asus website and downloaded the most current motherboard bios driver and I've gone hours without crashes. Also, my computer boots up WAY faster as well. Thanks for the tip.
I thought it might just work even though you had a totally different board. The odds were always in favour of the problem being a "feature" of the chipset, and common to most, if not all, boards. Certainly Gigabyte published updates to the BIOS for all their X79 boards at the same time 2 weeks ago.
