My r7 shut down for no reason while gaming and won’t start no up. No lights or anything left on, not even the alien face power button. I thought it might be my psu so I changed it but still won’t start up. I’ve change outlets, power cords, and like I mentioned even the psu. Anybody have this problem and no how to fix it?
Before your changed your PSU, did you try to reset the CMOS?
Were you overclocked?
A shutdown without subsequent attempt to startup via Windows is bad juju. Usually indicative of a hardware failure. The fact that you already replaced your PSU (correctly, I hope) and the computer still fails to power on, generally means the MB voltage IC or CPU VRM decided to say F this, packed its bags and went to Canada.
I got nothing else except to say good luck and I hope you figure it out. Personally if I were in your shoes, I'd start by looking for a new motherboard.
