Recently my computer has started shutting down while I'm playing a game or trying to do something that uses a lot of memory. I've dusted off my fans and cleaned out the inside of my computer as best i could but it didn't help. I downloaded SpeedFan to see what my temperatures are like and the GPU and CPU were 75 and 71 respectively. That's just idling which i figure is too high. I realized my dual screens was adding to the issue so i removed one of them and the temperature went from 75 and 71 to around 50 and 45. I thought that would sort it out so i tried updating/optimizing Diablo III which originally lasted 5 minutes before my pc shut off but it still didn't work. My pc still shut itself off. But my temperatures only reached 54 and 50 before it did.

I'm not sure exactly what it is since the temps didn't raise when it turned off but I figure it's still to do with overheating or power supply. My pc is around 4 years old but here are the specs.



*The RAM has been upgraded to 8GB since then.

Any help would be appreciated.

Try running your PC with the sides off for a while - - if it doesn't shut down like that you'll know for sure it's an overheating issue.

I bought a new power supply today and installed it but my computer still shuts off like it did before. If it's not power supply or overheating what could it be?

It turned out to be malfunctioning memory slots. Moved my memory into the other two slots and all is well now.
