computer POSTS and then shuts down
I have a 12 year old home built computer running winXP sp3 and a 1+0 Adaptec software RAID. Replaced Power supply with PC Cooling unit a couple of years ago. Have replaced several of the Seagate Cheetah drives as the machine runs 24x7. The other day the computer started up and shut down in 3 sec before I can enter the BIOS and without any beeps. I took out and replaced the battery to reset the CMOS. I can't find any obvious shorts. I doubt the power supply has gone bad, but I do have a tester, just haven't done it yet. Other suggestions?
I had this problem a year ago, but at that time it took 10-12 sec to shut down. At that time I removed, cleaned, reappied thermal paste and reinstalled the CPU which took care of the problem. Thanks.

CPU fan gone?
Large desktop fan blowing into guts to keep air moving and see if that keeps it up and going.
