Started alittle under 4 weeks ago. My PC which has been fine suddenly now restarts itself without a error message or blue screen. It just randomly turns off and then turns back on.
I have
Intel Core i7
Gtx970
2 8gb corsair vengeance ram.
Crucial ssd
WD blue Hard drive.
Asrock motherboard
Coolermaster V650 power supply
Ive already tested the ram by trying each seperately.
The one thing I've noticed is the fact that if I have my ssd (which is what my windows boots from) plugged in, I can no longer access the bios.
Ive run malewearbytes already and havent found anything. Im at my wits end and really don't want to buy a new ssd and windows( as I don't have the disk or code or anything)
Please help
 
Could be Ultra-Fast boot preventing UEFI access with SSD attached. If you can enter your UEFI without it, I'd see if you can disable that feature. Could be in the CSM or Boot section of your UEFI. I'm not sure why this would start now all of the sudden. Another thing to remember is that a bad PSU can damage components, so I'd be looking to replace yours ASAP.
