Shutting Down Automatically

Specs: Windows XP
Hello, here is an issue i am trying to figure out:
The computer is about 2-3years old, and doesnt seem to have any problems or any visible hardware or software problems, and no changes hardware or software wise ever.

Recently it has been shutting down randomely. Sometimes it will restart(Like a power shortage shut down) before i get the windows Xp screen, sometimes after i log in and 10 minutes of working on it, it just shuts down 1-20 mins of running completely randomly, it doesnt give a blue screen, it just acts as the power went off, now i opened up the case looked thru, and doesnt seem to have any fan issues, tried connecting/disconnecting parts, and even disconnecting all but the 2 main*(the 12pin, and the 4 pin). The computer has an active virus protection, which is on all of my 4 computers and its really good as i never caught any problems to virus/spyware related subjects.

So if anyone has experience same issues could give me a tip on how this can be fixable, it would be much appreciated.

boot to the bios and leave it on. If it shuts down you most likely need a new power supply.

make sure all the fans are working and the system is not overheating which can cause the mainboard to shutdown to protect the hardware.

If the shutdown only occures with windows up do a repair install of windows.

It shuts down before bios, while in bios, before logging in, or while logged in. I guess I will be getting a new power supply, since its not overheating, and all fans work.

^_^ darn i really didnt want to replace it.. thanx

Sill could be any number of things. If you have a known good test ps then use it. If not, reseat every item (be sure to protect esd). Clean dust out of PS outside with high volume low pressure air or esd vacuum. Try again.

"Best Practices", Event viewer, host file, perfmon, antivirus, anti-spyware, Live CD's, backups, are in my top 10

Does the power supply have good airflow through it? A fan that isn't working or dust bunny plugged ports inside can cause the supply to overheat.

Okay..a brand new power supply didnt solve the issue..I am going to clean all ports out and blow it out.

What could be this problematic that it auto restarts, like it lost power, anyone?? I am willing to try anything...

If after reseating everything, and the problem continues, it can be one of these

failed mainboard
failed ram
failed cpu

most bios's have a temp listing for the cpu/mb. if the cpu fan isn't spinning as fast as it should you should see the temp rise to the point the mb shuts the system down.

btw a crack in a mainboard tracing can still have a connection until the temp makes the mb expand enough to disconnect the connection. This isn't something you can see with your eyes.
