As the title states, my PC blacks out without warning (all fans and LEDs turn off, etc. etc.) and turns back on as if it were a regular boot. This has only happened while I am gaming so far, but a few minutes ago when I turned my PC on while the fans are running, it turned off like I described and turned back on (this all happened before the motherboard splash screen). This is one of the only events where it did something like that without me gaming. My part list is as follows:
i5-4460, 3.2 GHz
ASRock H97 Pro4
8 (4x2) GB of memory
SeaGate Barracuda 1 TB HDD
Sapphire R9 280
Corsair CSM 550w
Windows 8.1
I tried stress testing the power supply to see if it was faulty (with 10 minutes of FurMark), but it held. I have also tried to update all of my drivers and it was going smoothly for a couple of days, but it started to do it again recently. I have also monitored my temperatures and they all were perfectly stable. GPU never goes above 65 C, CPU as well as motherboard never above 50 C.
It is also worth mentioning that a few months ago the PC would half turn on (chassis fans and their respective LEDs would turn on, but none of the fans belonging to the CPU, GPU, etc. would turn on.) until I reconnected the 24 pin motherboard connector. It hasn't done it since. I have tried to check my connections, but it doesn't seem like it is at fault here.
Does anyone have any suggestions? Any help would be much appreciated.
