I was playing a game today and I began to smell a electrical burning smell and shortly after my computer started lagging and forced a system shutdown. It tried restarting itself but I stopped it and turned the power switch off on the back of the PSU to make sure there was nothing being powered in my system. About 10 minutes later I turned the switch back on and my motherboard and CPU cooler lights turned on (these always remain on while my system is turned off but the AC power is still connected). I then turned my computer on and my LED strip (Hue+ flicked on and off once and I heard a single click noise from my PSU and then it seemed to turn immediately back off (Though my motherboard and CPU cooler lights remained on so there was still some power coming through).
Any idea what it might be? I figured that it is my PSU causing the issue, but I can't test it since my computer won't turn on and I don't have a spare PSU around. I ordered a new Corsair RMi 750 80+ Gold which should get here by Monday, but that is a gamble since I'm not 100% it is my PSU or not.
Any thoughts/suggestions? Thanks
