Pretty much ever since I built my PC, it's been shutting down randomly. It shuts down, and it won't turn back on unless I turn the PSU switch off, and then on again. It starts up fine, and I get the Windows recovery error, because it didn't shut down properly. Once in a while when I switch it off and on it starts up and then shuts down right away before POST. I suspect it's the power supply, which is a Rosewill Hive 650. I'm running Windows 7. I know it's not the CPU because the temps are fine and it doesn't always happen when I'm gaming or doing anything intensive. I've also tried switching the RAM, didn't work.
Here are the rest of my specs:
AMD FX 8320
GA 990FXA UD3
Corsair Vengeance 2x4gb
Evo is redone, also did some dusting to my GPU and Evo radiator. CPU is idling at ~18-27°, compared to ~32° before, so there's a difference. I'll get back to you if it happens again, again, thank you for your assistance! I appreciate it.
EDIT: It just happened again, reset the PSU, and turned on fine. Also, I know it's not my OS because I have re-installed it and the problem persisted.
ok. now we gotta check for something OTHER then the cpu overheating.
pop the side of the case off and stick a room fan in the opening blasting on full blast. then do what you normally do and see if the problem goes away. if it does then we are 100% sure it's a temp issue.
Did the fan, it happened again, once I rebooted, it happened again within 5 seconds. I installed speedfan and checked the temp logs and they weren't high at or before the shut down. In that case, do you think it's the PSU?
1) check your motherboard... make sure you have spacers propperly placed, none that were placed incorrectly
2) check your wires... make sure the wiring is all "tight" what i mean is wires should twist and turn in your figers if you pinch them by the molex or 3 pin plug and twist. make sure they're all firmly attached to their plugs.
3) check the cpu fan manually. flick it with your finger to get it to spin. it should spin soundlessly and freely. watch it for when it reaches the end of the spin. make sure it does a small "bounce" backwards in the oposite direction in the end. if the fan doesn't do both of those things then the fan is dying.
4) check the gpu fans for the same thing
5) breadboard the system
6) try another psu.
