Hey guys I am having some powering on problems with my computer. Orginally the power supply died and and I installed a new one. Afetr installing the new psu my computer would power on and than power off either immediately or a about half a minute after turning on. I cleaned out all the dust in the case and the computer powered on and worked as normal. Occasionally it would power back off and not turn on correctly. Now it is back to the point whee it powers back off immediately. Does anybody have any troubleshooting tips or idea wih what might be wrong? Id apreciate it thanks!

Did you check CPU temps and check your thermal paste? Also are you plugged into a power surge protector? It also helps to list all your parts as well.
It is plugged in to a surge protector. I built it with a friend a few years back and Im not really much of a pc expert, but the basic build is a 500w coolermaster psu, intel i5 processor, antec case, gigabyte motherboard, and a amd radeon graphics card. Also the thermal paste should be good, i has worked for two or three years until now, unless it has to be applied regularly?

No thermal paste is usually good for quite a long time if it's only been 2-3 years I would say that's not the case. I did have a friend who mentioned random shut downs before and a surge protector fixed his issue. It would simply be a actual power issue with the PSU what type of Cooler Master is the PSU? I felt it was CPU temps cause of the fact that it actually turns on and then randomly shuts down I figured temps were getting up there. In all honesty it wouldn't hurt maybe checking to see if the thermal paste got dried up idk what brand thermal paste you used. Most of us on here use Arctic Silver. I am sure you did too but if not applied properly reapplying it sooner may be need.

Ignore speculation about thermal compounding. The Intel CPU only slows it if gets too hot. If thermal compound was defective, then the computer never worked in an ideal enviroment such as a 100 degree F room.
A power controller decides when a computer power cycles. Only way to say specifically what is wrong is with numbers from a meter. Any layman or junior high science student can use one. Then the few who really know this stuff can say what is defective.

No.
One minute labor, defined by requested instructions, provides numbers that define an entire power system. Only then can those who really know this stuff then say what components are and are not defective ... without speculation.
