Asus P4C800-E Deluxe - Problem with computer restarting on its own

I was wondering if anyone can shed some help with a problem i seem to incurring...

I have an ASUS P4C800-e Deluxe motherboard, 2 X 512 MB DDR PC 3200, 1 X 320 WD HD, an ATI All-In-Wonder 9800 Pro, running with a 430 Watt Power supply

Now the problem is that i recently bought a new hard drive (the 320GB) and tried formatting to use but every time it was in the middle of formatting the drive the pc would restart itself or shut off completely. After a while of trying it over and over I finally got it to format using the NTFS quick format and eventually after many restarts got it to install windows. The problem is that the computer still continues to randomly restart itself for no apparent reason. I have had this system running for over 3 years in the past using a 120 GB HD that i replaced. I have read that if the cpu overheats it can cause restarting. MY ASUS Probe says my CPU is sometimes 49 C and sometimes 83 C. I have tried removing and replacing the RAM with no luck in fixing the problem. Could it be my power supply (which I doubt seeing that it has been working for over 3 years with no previous problems). Also i have switched the hard drive 3 times at best buy to ensure that it wasn't a bad disk. Any help would be appreciated.

Have you checked the motherboard looking for bulging or leaking
capacitors? I had to RMA my P5P800 a few months ago as I was getting
the random reboots even while it was idling. One of the capacitors
below the CPU was bulging noticeably. The replacement motherboard
hasn't had any problems.

I would try to swap PSU after checking what Anon and Michael sugested..

I have a P4C800-E Deluxe 2gb, X850XT & a couple of Raptors, I was getting
random shutdowns usually when the disk was being accessed intensively i.e.
playing a games etc
The issue was a Tagan 480w 3 yrs + old power supply, replaced it with a
corsair hw620 and it has been fine ever since..


>MY ASUS Probe says my CPU is sometimes 49 C and sometimes 83 C.
Check to see what the bios is reading, 83C is way too hot, mine would idle
at 34C and load at 55-60C and that was a 3.4Ghz P4

Good luck

I have the same board and it has never run above 53C. What about
your cpu cooler- is the fan working? Do you have any idea what the
temp. is when it randomly reboots? Is the new drive SATA or IDE? You
may want to run SeaTools to check the drive- if it started to reboot
after the new installation, the drive would be the suspect. Correct
me if I'm wrong, but the motherboard isn't going to recognize all 360
gigs of that hard drive, will it? And it wouldn't be a bad idea to
swap out the power supply and see if that's the problem. Good luck
