Hello,

This is my first post here, so sorry in advance for any formatting mistakes.

My first build was working flawlessly for the last month, but I was playing games this morning and all of a sudden the comp shut off and now will not boot up - no post nothing.

The red CPU light is solid on my mother board as well. See spec below:
CPU: Intel i5 Kaby Lake 3.8ghz
CPU Cooler: CRYORIG M9i 48.4 CFM CPU Cooler
MOBO: MSI B150 Gaming M3 ATX LGA1151 Motherboard
GPU: PowerColor RED DEVIL Radeon RX 480 DirectX 12 AXRX 480 8GBD
RAM: Team Vulcan 16GB (2 x 8GB) DDR4-3000 Memory
SSD: Samsung 850 EVO-Series 250GB 2.5" Solid State Drive
HDD: Western Digital Caviar Blue 1TB 3.5" 7200RPM Internal Hard Drive
PSU: EVGA - 80 PLUS 600W ATX 12V/EPS

The CPU heatsink fan is not spinning when I power on the computer as well.
I have taken off the heatsink and fan and resinstalled with new thermal paste. nothing.
I have reinstalled the CPU as well - did not see any bent pins.

I did have the heat sink fan plugged into the sys_fan header. Would this mess up my mobo or kill my fan? Does my fan need to be running for CPU to start up properly?
I have plugged the fan into the cpu_fan header and cpu_fan 2 header. nothing.


Any suggestions? I am at a loss and I'm worried I fried my CPU :(

Yeah, it has been working fine for over a month now.

Turned it on this morning and was playing overwatch for about 10 minutes, then shut down out of nowhere.
