PC Shut off randomly while gaming, now doesn't get past post beep, cannot get to bios.

SOLUTION:
I finally found out that it was my H100i pump not being detected by Corsair Link. When the computer was under load it didn't tell the fans or pump to go faster so it just overheated and shut off. This apparently happened when I changed motherboards and the H100i v1 does not support my newer MB. So I put in a stock cooler and it works perfectly fine now. And I will be getting a better one shortly.


OS Windows 10 Home
CPU AMD FX 8350 Black
CPU Cooler Corsair H100i
Motherboard Asus M5A97 r2.0
Memory Ripjaws Z 2X8GB 1866
GPU PNY GTX 780
PSU EVGA 1000G2 Supernova (I know this is overkill)

Problem

I could play games just fine for a long time. Suddenly the computer shuts down without warning or error messages when playing any game. It does not do this for normal tasks (i.e. internet browsing, video streaming, etc.) Was playing GTAv, mirrors edge, witcher 3, etc without problem since it has been out on PC, now it shuts the computer off 5 minutes into the game.

Things I've tried or looked at

Event vierwer shows Critical Error - Kernel Power - Event 41 (63)
Tried running prime95 and windows memory test, but it shuts the computer off the same. Tried reseating the memory and making sure everything is plugged in correctly. Tried swapping with different memory sticks. Not sure if PSU related but that's the best I can come up with, I just don't know how to test this. Tried moving the main power cable from a surge protector to a main outlet. Temps look pretty normal in HWMonitor. Tried reseating all cables and switched CPUs, same problem persists. The computer runs fine when not playing a game or stress testing.

NOW after all that:
PC shuts off after post beep. Can't get it to go into bios as it shuts off too quickly

Not sure if my PSU is dying, only 2 years old
 
Solution


first of all you can't always trust HWMonitor to read the temperatures correctly.

If it restarts when you're stress testing or playing a graphic intensive game then it makes me want to believe that it is temperature related. Your computer restarts like a safety function so it doesn't overheat.
If it doesn't let you boot, then you let it rest, then it lets you boot - then it's likely she was too hot.

hate to state the obvious...

hate to state the obvious, but make sure your fans and the heat sync on your CPU and graphic card are completely dust free, would never hurt to invest into an additional fan.

Thanks for your advice, it was temp related. I entirely forgot to update this.
