Default Computer Shutting off

When i start my computer it either shuts off about 5 sec after i turn it on, it will shut off in about 5 or 10 min. or it would shut off after about 20 min, from the time i turned it on. It just shuts off at random times.

I dont think its overheating becouse all the fans are working, the computer doesint get loud after it shuts off, and after it shuts off the computer is still cool.
Windows starts up nornaly and everything seems fine except the computer just keeps shutting off. Can someone please help me out. Thanks

Check your ram, and video card are seated correctly, next check them and the heatsinc for dust and clean, give the inside of your case a vacuum carefully to remove any more build up of dust, use a little fine brush to go round the jumpers , If this doesn't work, then run a scan disk of our HDD, run memtest to test your ram, try running it on one stick to see if it makes any difference, run an virus scan , if then its still not running right try a repair install of XP or reformat, if that doesn't help then start looking at your PSU OR HDD.

I would also try running memtest on the system. Random shutoffs can be caused by RAM issues.
