My PC turned off and wouldn't turn back on, I changed the motherboard and power supply and it came back on but then kept rebooting a few minutes after I booted it, after a few reboots a blue screen came on and it said 'critical process died' and then it wouldn't let me start my pc up again, just kept taking me to the repair screen. after a while, I decided to just restore my PC which I didn't want to do but it worked, it came back on BUT THEN, it started rebooting again! I tried updating drivers but PC kept restarting before I could, I tried restarting the CMOS battery, didn't work, I tried disabling all the Microsoft apps to see if that was the problem but that didn't work. So I booted in safe mode to see if my PC would restart and it doesn't it stayed on. If anyone can help me I'd be forever grateful!
