My PC has been randomly shutting down for 5+ months, usually doing somehting intensive like playing a game. Tried to track it but nothing pointed to any issue. Temps were fine while gaming.

I was just playing Black Ops 4 and it shut off. I decided to go to bed at this time. Next night I try and turn my computer on, wakes up from being in sleep mode when I press a keyboard key but monitors stay black. I look into the computer and my motherboard has a Red CPU LED lit up.

I've removed sticks of RAM and tried booting nothing. Removed video card and tried booting, I've tried all the configurations. Removed motherboard battery and still no boot up. The second I hit the power on button I have a RED CPU LED.

CPU:AMD FX 8350. 4.0 GHz

GPU: ASUS R9 280 (980 MHz)

RAM: 16GB

Motherboard: ASUS M5 A99X evo

Powersupply: Rosewill bronze 750W

No idea where to go next. Just recently cleaned it but PC was working fine after that.
