RANDOM "HALF" SHUTDOWNS. Odd behavior. HELP!!!

[brickson98]

So my system randomly shuts down. My event viewer log is disturbingly full.

Anything that could be causing it. It's only like a half a shutdown. Basically, random peripherals lose power (I can tell because my keyboard, mouse, and headset all have lighting) and my screens won't come back on when I wiggle the mouse or tap on the keyboard. The fans are all running, and graphics card illumination is still on, as if the system is still running. As per event viewer, it created an error event ID 6008. Unexpected shutdown. But then, it creates another critical error ID 41 when I actually flip my PSU switch off (holding down power button or clicking reset button doesn't work when this happens). I can tell when they're logged by the times. For example the most recent shutdown error happened at 3:47am on 5/7/18. The critical happened at 7:34pm on 5/10/18, which is today when I flipped the power off and on again. I'm thinking it's a hardware issue with my PSU or mobo. Any help is appreciated.

Please post your complete system specs. Especially the PSU since it's the most likely suspect. You have to test your system with another "good" and reliable PSU in order to know more about your current PSU's condition. Good luck.

sorry for the late response, haven't been on my computer much recently. Specs are AMD Ryzen 5 1600x, 16GB (2x8) Corsair Vengeance LPX, Asus B-350-F mobo, EVGA 850watt PSU, EVGA GeForce GTX 980Ti

A lot of things can cause this issue. If it's hardware related, it could be the PSU, the motherboard, the GPU or (perhaps) the RAM. It could also be software/BIOS related in which case a simple thing like a BIOS update or a CMOS reset may fix it. Having said that, you should always start your troubleshooting efforts from the PSU especially when you are dealing with power related issues since it's the number one suspect. Try to borrow another PSU and test your system with it. Only then you'll be able to know whether your current PSU is responsible or not. If your PSU is fine then you can begin checking the other suspects in your list. Good luck.
