why does my computer restart by itself after working for only 20- 30 min?

Question

My computer restarts by itself after working from 20 - 30 minutes.

Answer 1

Try running your PC with the side panel open and an electric fan pointed towards the motherboard. If problem stops, you just need to improve airflow in your PC case. If problem still persists, your power supply could be unstable or there is a problem with RAM.

Answer 2

Overheating may be the problem .. check the temperature of the processor using some software.. asus come with bundled tools to monitor the temperatures and speeds of fans..
the overheat protection on your motherboard will reset ur comp the moment the temperature crosses the specified tolerance limit..
check if your cpu fan is working properly .. stock fan shud be atleast 3000 rpm ... clean your heatsink and fan...
