Computer keeps rebooting

Ever since my video card overheated and one of the capacitors on it exploded my computer has been rebooting.

Here's the story: After the video card died I purchased a new one and installed it onto the motherboard. I booted up my computer and everything was fine. A few minutes later my computer suddenly turned off and rebooted, and kept doing so. I decided to turn it off and figure out what was wrong with it. A few hours later I turned it on again and it booted up fine, and I was able to get into XP. But a couple minutes later it shut off and started rebooting again. I tried getting into the Bios several times, and as soon as the Bios screen shows up it reboots. Is this a motherboard failure, virus, hard drive failure??? I would appreciate your help.
 
It could be your power supply is on its way out or your cpu is overheating and your motherboard bios has it set to shutdown when the cpu reaches a certain temperature.
 
it is not the power supply...i took it out and put it on another computer, it booted up fine. the cap that blew was on the graphics card (next to the heatsink and fan). and now i'm not even able to reach the windows logo screen and forget about getting into the bios. are there any tools out there to test exactly which hardware is faulty? i'm thinking it's the motherboard, but my model is discontinued and pricey now. i want to be absolutely sure it is the motherboard before i pay a little extra money for the same exact one.

btw...thanks for responding to my post
 
Just because the power supply works doesn't mean it's OK. Problems usually present themselves under load. While gaming is the most common, but I've seen them reboot right as they get to Windows. Try another power supply in the computer.

Also, I'd suggest checking over the caps on the motherboard and confirm none are bulging, leaking or anything.

If the caps blew on a gpu then it sounds like the psu has had some kind of failure, unless the card was extremely old...
 
so i just bought a brand new power supply with more wattage. i installed it and powered up the computer, and i immediately went to the system bios. in the system bios i went the pc health and realized that the cpu temperature rising a degree each second. when it hit 65 degrees C it immediately turned off. so obviously the cpu is bad right?

btw...my cpu is a Pentium 4 631 Cedar Mill, 3.0Ghz HT. i only bought it a year and a half ago, installed it with the stock cooler, and my case has adequate ventilation. I would appreciate further help.
 
problem solved, thanks everyone for the help. i took off the heatsink and put it back in, booted up and now the cpu temp idles at 10 deg C (35 deg C @ full load). before this whole mess the cpu idled at 31 deg C and it reached 55 deg C under full load. is it normal to have the cpu @ 10-35 deg?
