sounds like a bad PSU unit. But I would try reconnecting all cables, reseating all ram and PCIe cards and see if that makes a difference. what type of power supply unit you have?
Would that make sense considering it only crashed when gaming?
yes actually it would. gaming stresses the power supply differently the say watching a video or web browsing....and depending on the game it may stress your PSU different then your other games. Could well be an early warning sign. But could be nothing to. As far as your PSU when i asked type i should have been more specific. make and model....
If it's not in the first two tiers of this list....get a new one. or if its a second tier one you had for 3+ years, get a new one. Not on the list? Find out what tier it is on googling..
