We just had a power outage and I didn’t have my PC on a UPS (it's in the mail now). So it went under and has not come back up yet. It will turn on and off with the power button but shows nothing but a black screen. It will not boot into bios. All of the fans spin and the hard drive that’s in there (I have an SSD and a HDD) makes noise so I can tell most everything is getting power. Everything else connected to the motherboard seemed to be working - All fans, gpu, HDD. So I swapped out my CPU with the old one (just upgraded from i5 to i7) and still no luck. The last thing I tried was swapping the ram around in their slots and replacing the ram sticks with different ram but that didn’t do anything either. I also completely removed the gpu to see if that was causing an issue. I'm now under the influence that it's either the mobo or the psu. Any ideas what it could be? Should I take it to someone?
