I THINK this is a motherboard issue. I have a Gigabyte GA-F2A88XM-D3H mobo with an Athlon x4 860k and an EVGA GTX 950 SC GPU, running off a 580W PSU with Windows 10 64-bit. This computer has a history, so bear with me.

` 2 Years Ago `
I built a computer using this mobo a07nd an AMD A6-5400K APU. No issues.

` April 2016 `
My PC was okay, but I wanted to start a YouTube channel and really do game development, so I needed a PC upgrade. So I purchased an AMD Athlon x4 860K, and used an old Radeon Sapphire 4870 HD card I had hanging around. No problems until...

` Early July `
Playing Minecraft, recording a video. Out of the blue, the display shuts off, and the fans in the case start spinning on all cylinders. So I shut it off through the switch on the PSU, wait a few minutes, and turn it back on. No problems, until I try to boot two days later... nothing. The mobo doesn't beep like it does when it successfully boots, and the twin fans on the GPU are spinning erratically. So I switched back to the APU.

` Early August `
I ordered my current graphics card, the EVGA GTX 950 SC, thinking it was just the old card's fault... right? Put the Athlon back in, installed the EVGA, worked like a dream, but you can probably guess what's going to happen next...

` Last Week `
Playing Epic Game's new MOBA Paragon... and the display shuts off. I swear loudly, and manually power off the PC. Thinking that the PCI-e slot's dead, I switch it from the x16 to the x4, after some frankenstien-esque inner component reconfiguring. It works like a dream until...

' Yesterday '
Playing Paragon again. PC shuts off. I swear twice. So I switch back to the APU, remove the GPU, and boot. Nothing happens. The fans are all spinning, the lights are all on, but the speaker doesn't beep and the monitor doesn't turn on.

WTF is going on?
 


Eww. It's not definite that it's the PSU -- you can never be positive about these things -- but it's really hard to diagnose things when you have chunk of junk powering the whol thing. Replacing the PSU with a dependable one would be the first thing I would do, then re-evaluate the situation.
 


PSU swapped. Poweded on with the GPU in the x16 slot, and... nothing.

Now what?
 
i have a similar problem on my system, no problems with an APU on games, etc but with a dedicated GPU all games simply freezes the system (black screen, pc keeps turned on, need to do a hard restart). solution, i grounded the house wall sockets and no more problems
 
Solved! Turns out my PSU was super crappy (thanks, Greens) and when I replaced it, the one I swapped in was even more crap. So I bought one, plugged it in, and my PC's running fine again. Thanks, everyone! Anyone using a PSU like mine - be warned that one plug can't give enough power to run the GPU.
