Do you have another PSU or a friend with one you can borrow?
9 times out of 10 a reboot while gaming is either a result of overheating (either processor or VRM's) or the power supply is not capable of outputting the required power or outputting it stably.
No, sorry
I apologize for derailing the thread.
As for whether or not it's definitely the problem... Even if it isn't the problem, it will cause problems in the future.
Do you have a device that can measure voltages? (like a multimeter)
