I just built my first computer. Whenever I turn it on, it stays on for about one second then shuts off again. Does anyone know what could be the problem.


Someone told me that it could be the power supply.

here are the specs for power supply and motherboard.

It could be that the heatsink doesn't sit properly on the cpu and the cpu is overheating to such an extent that it shuts off the computer almost instantly. Check this first to avoid damage to the cpu.

It could also be the cpu overheating.
Did you put thermal paste on the cpu/heatsink? and how much?
Is the processor/ cpu seated correctly? no bent pins.
Is the heatsink and fan on properly/ seated?

hmm i did put thermal paste on, but maybe not enough. I will apply some more and see what happens. I will let you know how it goes. thanks for the help.

Thermal paste should be applied very sparingly. Only a very thin layer on top of the cpu and bottom of the heatsink. Too much paste will get you negative results.

I don't believe that this is the problem. You can install a bone dry heatsink on the cpu and it won't shut off that fast. Take out the cpu and reseat it, checking first that no pins are bent or broken. Re-apply a very thin layer of thermal paste and re-seat the heatsink, making sure that it sits tight on top of the cpu. After installation try to twist it lightly sideways to make sure that it sits properly.
