I have an assembled sempron 3000+ CPU based PC, for last few days i am experienceing a strange problem, My PC doesnt start if i press power switch, only the SMPS fan rotates for a while and stops. If i press the power button again nothing will happen, i'll have to Restart the UPS. The PC starts if i repeat this process 10-15 times. Also it will stop suddenly after working for some time.

please suggest me some remedy.

I would start with the power supply.

This behavior is usually 1 of 2 things.

Either the power supply is bad (or too small), or there is a problem with the power control circuit on the motherboard.
