Power Supply Changed & Still Having Problems

[edgewoodzgimp13]

So I've had my computer for about 3 years and one day it wouldn't turn on. I assumed it was the power supply so I bought a new on online. I installed the new power supply and it seemed to be the problem. The computer boots and will run for about a minute before it restarts itself. I connected all the cables correctly and I don't know what else the problem could be. Any ideas? Thanks guys!

check that your cpu fan is running. It could be an overheating issue with your chip.
