PC Black Screen When Gaming But I Can Hear Everything

[BarbieButt]

As the title says, recently, I have had the problem where my PC will black screen, but all my games will continue playing in the background, I can hear game sounds and chat with my friends, but the screen will be black. The GPU fans will go to maximum and stay like that until I hard reset the PC. I have looked through other threads and nothing has worked.

I have tried many things, including MSI Afterburner and lowering the GPU settings to the minimum, but it still crashes. I have monitored my temps and they are fine, never really much above 65-70C while gaming. I tried running a GPU stress test, FurMark, but it instantly caused the PC to crash. I unplugged one of my monitors, still crashes, unplug a second, still crash. I looked in Windows Event Viewer and all it gives me is "Critical - Kernel Power - The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly."

My PC specs:
Motherboard: Asus H97I-PLUS Mini ITX LGA1150 Motherboard
CPU: Intel Core i5-4690K 3.5GHz Quad-Core Processor
Memory: 16GB total, Kingston HyperX Fury Blue 8GB (1 x 8GB) DDR3-1600 Memory
GPU: Asus GeForce GTX 1070 8GB Video Card Strix
Power Supply: Corsair Builder 600W 80+ Bronze Certified ATX Power Supply

I have narrowed down my options to two things, need a bigger power supply, but I haven't had this problem until last week, or a better CPU cooling system, but I have never had a problem with high temps at all. I can try adding more thermal paste but I don't thing it will help much. Please, any suggestions are greatly appreciated, Dark Souls 3 DLC needs me.

So, you either have a power supply problem or your havent shut down your computer properly and messed up your motherboard.

If you turn off your computer by holding down the power button it can cause all sort of ruptures in save files, motherboard destruction and ESD rupturing throughout your case. If this is the case, your going to need a whole new motherboard.

Yoru specs compatiblity are all fine except for the power. It can barely keep up with the specs, maybe when it was new it could run at higher capacity for longer, but I recommend a new power supply at least 800 W, unless you've done what I explained above.

I thought I would need a new power supply also, but I shut down my computer every night, never holding the power button. I haven't had this problem before, so I was not sure what could have happened to cause it so suddenly. The power supply came from an older build, but worked when I first built this one fine until recently. Guess it's time to finally let her go. Thanks.
