could be your power supply needs replacing.

Any changes that either happened or that you perhaps made to your computer around the time that the problem started; particularly any Software or Hardware that you installed or setup.

check you motherboard fan is working properly or not..

Check the all FANs in the case. Make sure they are spinning and are dust free.

Its almost alway the CPU temp. the CPU has a fail safe temperature at witch it will shuts down to PC to prevent damage to itself. Normally 70-80 deg C

If all is well check power supply.

Hope this helps :)

Go into the Control Panel \ Administrative Tools \ Event Viewer and post any flags relating to a shutdown. It could be software or hardware so post both.
