Question

PC randomly shutting off

Apr 5, 2018 10:21PM PDT

well yes, i had this computer since a year ago, everything was okay, last week after 5 hours of gaming the computer shut off and restart without any warning, i suppouse it was heat so i open the pc and clean it, i also change the thermal paste, anyways, the computer keep shutting off after a few hours playing

generally it shut down after 5 or 6 hours playing, but it seems a bit random, i mean one day it shut off after 1 hour of using it and today it just shut off after 2 hours and i really dont know what could it be

could you people please mention some of the reasons this could be?
i mean maybe the fans are failing but they dont seem like it, they are just spinning...

When you cleaned the innards did you use compressed air?

If so did you give the psu a few shots of air from both directions?

If this is a desktop have you tested with the side panel off?

Get some compressed air and give the psu a few shots from both directions.

Look close at the cpu heatsink it can get clogged up with dust.
