I've been dealing with a strange issue recently. Under load (while gaming, and once during furmark) my screen will go black, sound shuts off, and I'm forced to reboot. All my fans and case lights remain on but my monitor reports no signal. I'm running audio through the mobo, not through the GPU HDMI port. I initially thought CPU overheat and attached a Hyper 212 EVO and dusted everything out, but it didn't help. GPU temps seem to cap out at about 66C during furmark and 100% load. Memtest86 came back clean after 8 passes. Reliability history reports TDP errors before the black screening. Issue persists across 4 different GPU drivers.
I also noticed that under load my room lights start to rapidly flicker. Plugging in a lamp to a nearby outlit and turning off the ceiling lights results in the lamp flickering. House is ~4 years old and I'm the first resident so I don't think it's bad wiring.
At this point I'm thinking it's a faulty PSU but wanted to get another opinion before dumping money on a new one. For what it's worth it's about 6 and a half years old.
Specs:
Asrock B75 Pro3
I5-3450
Sapphire 390x Nitro (no OC except for the factory)
PC Power and Cooling Silencer MK.2 750W.
8-GB (2x4GB) Gskill Ripjaw DDR3 ram
Win-7 64 bit
