Computer shuts off while gaming

[JorgenValdia]

Everytime i play a game that is graphic intensive my computer will just shut off, but the fans will continue to run. I have cleaned everything out so im pretty sure its not an over heating issue. Im wondering if my power supply is going out, or if its not enough for what i have in it right now.

You could try to HWMonitor or Speedfan to check your temperatures after gaming. Or even better, use Everest Ultimate Edition and turn on the temperature logging feature (go to Preferences - Logging) and play until the computer shuts off. Then turn it on and check the log for high temperatures. I´m not sure if you have to register Everest to be able to use the logging feature.

I had a similar problem with my laptop, the GPU reached 100ºC after 30 minutes of graphic intensive programs, and it shut itself off to avoid damage. It turned out the fan was covered with dust, so after cleaning the problem disappeared.

I checked it and the GPU temp never went over 63C and the cpu never went over 31C.

I recently changed out the power supply, but the problem is still occuring, Anyone know how to check if the motherboard is the problem? Any help will be much appreciated.
