Quoted:
My son has a Dell desktop that's a little over a year old. Periodically (he says only when he's gaming) it'll shut down on him.
We opened the case and blew out what little dust was in there. Both fans are working. I removed and re-seated all of the RAM, since I read that could be the problem. He says he has all of the latest drivers installed.
He ran a temperature check program and got 62C on the processor after a re-boot, which supposedly isn't unreasonable.
He tried running it with the side of the case off, and still got a re-boot.
Short of shotgunning it and replacing the power supply, does anyone have any thoughts on what could be happening or suggestions to troubleshoot?
Shut down HOW? Shut down in a blue screen? Shut down as if someone unexpectedly cut the power?
If a random, intermittent shutdown, try the simple thing first...the power button wires in desktops can become loose. That is your first culprit––especially since you seem to have checked everything else. Hopefully the new power supply solves the problem, but hopefully not (so you can return it if the problem WAS the switch..
).
