Last year I bought a whole new rig, save for some fans, my 1000 watt power supply, and my hard drives. I took part in the Battlefield 1 open beta last year, and while I was playing it crashed on me. BF4 used to crash on my old rig all the time so I thought nothing of it and moved on with life. Then Overwatch, which never crashed on me, suddenly started to after a few hours of playing. More and more games started to crash after that, including Middle Earth, Shadow of Mordor and ASTRONEER. Some games like the Left 4 Dead games stutter or freeze for a split second, appearing as if it's about to crash, but it's a crap shoot whether or not they do.
One of my friends who put my PC together for me suggested furmark to stress test it, but overheating didn't seem to be the issue. The weirdest part of all this is that he sent me a program that deletes all of your graphics drivers and when I reinstalled the current ones, the problem appeared to have gone away for a short while, but resurfaced out of the blue.
What happens when I crash:
My screen freezes, the lights on my keyboard + mouse turn off, and the light on the front of my case stops flashing. Reset attempts do nothing, my fans keep spinning, only way to stop it is to cut the power.
I saw a topic earlier that mentioned speccy, so I went ahead and ran it:
Also, since there really isn't anything I NEED on my PC, I've contemplated moving all the word files I want to keep on a USB, totally wiping my bigger hard drive and just starting over with windows 10. I'm probably gonna do that anyway, but I still want to know what the real issue is here so I don't lose my mind when it crashes again. I'm pretty basic when it comes to PC knowledge, so if you guys need any more info I'll do my best to dig it up thanks in advance for your help!
