Ever since I got my sexytime GTX 770, I've experienced random shutdowns for no reason. I don't get a blue screen nor do I get a crash dump. It's like the power goes out. No warning.
I have an 850 watt PSU that is about a year old. It supported the Radeon 7770 just fine. I checked the voltage readings via UEFI and everything is a little bit high, but the main 12V rail is 64 amps on this thing so it's certainly not a power under draw. How much higher than the actual voltages can hardware support? The 12V is actually at 12.4 - the CPU is 1.02 - the 3V ones read at 3.3V or so.
The first time it happened I got a good crash dump which said it was AVG. So I uninstalled AVG and went back to Windows defender.
I've even taken apart the box and reseated everything. Just in case I didn't have something socketed properly.
Is there any way to check the health of a PSU outside of using a multimeter? (I'd electrocute myself, I am sure.)
