unexpected shutdown computer.

[magnobot99]

My computer has been shutting down unexpectedly. I dont know if its from overheating . I dont think it is. I brought it to best buy a while back and they said I needed a new ram card so I bought it. It worked for a while but now its doing it again. It passed all the other tests. What should I do? What could it be from? I cant even play minecraft for 10mins without it doing it anymore. Please help. I have a AMD 8 core processor.

Highest suspects then are overheating or your PSU.

Start with overheating. Use a program like realtemp to monitor your cpu temperatures while gaming. After gaming for 10mins or so, hopefully before you crash, go back to realtemp and see what it is reporting your max temperature at.
