My pc crashed on tuesday night. It went to the Bios screen, then seemed to be alright. I was able to log on to my account and to a standard shutdown and left it for the night.

The next day it wouldn't turn on. I let it sit for a few hours then tried a new outlet. It turned on, but I get no signal from it. My moniter registers no signal, my usb keyboard stays dead. And while its on I cannot turn it off by holding down the power button. I have to use the switch on the back of the power supply.

Please help, I have no idea what could be wrong or what to look for. Any help would be greatly appreciated. I just put a new graphics card in for Fallout 4, and not being able to use it is killing me.
