Solved Computer Shuts off Randomly

Specs: Windows
My computer shuts off shortly after being turned on. Occasionally, it stays on, but for the most part it shuts off about 3~5 minutes after being turned on. I don't believe it's a faulty power supply, because I tried installing a brand new power supply, and the problem still consist.

✔ Best Answer
Randomly replacing parts is not a good method of troubleshooting. Random shutdowns are often caused by an overheating CPU. Make sure the CPU heatsink/fan is free of dust. You didn't provide any info about your system, but try monitoring the temps, either in the BIOS or thru software. If the CPU quickly reaches 60C+ at idle, it's possible that the heatsink was somehow knocked loose; in which case, it will have to be removed, cleaned, & then re-installed along with fresh thermal paste.
