system freezing frequently (no BSOD)

[CorusMaximus]

Hello all,
I am posting for a friend who is having problems. (computer specs at bottom, along with idle temps)
His computer while playing MWO, the game froze and there was a deep buzzing sound the system would not respond to control+alt+del or any other commands. He had to kill it by holding down the power button.
He rebooted and it froze again while trying to use Firefox to research his problem. Same thing, he had to kill it via power button.
The next day it froze while playing This War of Mine. Same thing. Then he rebooted and it froze twice. The third time he rebooted in safe mode and it froze again.
He opened up the case and check for leaking or busted capacitors. As far as he knows his fans are still working. He ran the HDD check in windows. No problems found.

your ( friend's ) cpu is overheating
51'C at idle is too high
use hwinfo42 ( sensor tab ) to check cpu temps while idle and while doing some work
if it shows 40-50'c or higher during idle then its confirmed that its cpu overheating
this can happen due to dust in heatsink or cabinet or due to old thermal paste
so clean cpu heatsink and cabinet from inside and reapply new thermal compound during heatsink installation

also list your smps make and model and voltage at +12v, +5v adn +3.3v from hwinfo64 sensor window

Really? It wasn't entirely idle, he was using Mumble (VOIP) to talk to me, but that is not very processor intensive. Thanks I will have him look at his heat, airflow and thermal paste situation.
Thank You!
