If I had to guess the PC worked fine before so your next step is to put it back the way it worked.
I got a NZXT kraken x42 for my birthday. My pc was working for around 20 minutes, then a blue error screen popped up then restarted my my pc, that happened 4 times, then everything got really hot and wouldn't turn on.
Now when I turn it on my computer starts up but my keyboard, mouse and monitor do not connect.
MY pc has.
A gtx 1070
Cpu is an i5
32 gigs of DDR4 ram
NZXT kraken x42
4tb of memory
Power supply is a Corsair CX550M
Does anyone have any idea what happened and how to fix it?
