G'day, I recently upgraded my p6-2155a so i could play some better games on it. I bought a sst-st50f-es silverstone PSU and a Nvidia geforce gtx 560 second hand. my PC started crashing at random points in some games so i thought it was an over heating issue and upgraded again. So i bought a thermaltake urban T-31 and installed two more fans overhead, as well as installing a samsung evo 880 120 GB ssd and seagate 3TB hardrive. The computer still crashes as well as the USB 3 ports on the new case don't work. I'm not sure if the issue is software related or my PSU isn't large enough or something else all together.

From what i can tell, all drivers are up to date (although device manager doesn't recognise the USB 3's at all) and its crashed before with the highest temp being the CPU at 50 deg. Celsius. If it helps, some games like Warthunder and Far Cry 3 crash at random times, but i've managed to play Crysis 3 with high graphics for long periods of time.

If someone could please help it would make me a very happy man, cheers!
