So Yesterday I was browsing the Internet on my newly build pc, when suddenly I was taken to the windows installing updates screen. So I waited and then rebooted, but my screen had a small A2 at the bottom of it. So I reboot a couple of times to see if it would eventually start up but to no avail. After a while I try again but I notice the pc doesn't start up at all, so I check my mobo connections and the power button on the board is still lit. But after a day it still won't boot up and I am getting frustrated. My only thought is a dead psu. Please help!!
