My pc just froze about 30 mins ago and I shut it down by holding the power button. When I tried my 1st attempt to boot it the pc shut itself down when it got to windows. I tried another time to start it up and I got a black screen and I held the power button again to shut it down. This time I unplugged my psu and left it for a few mins afterwords I replugged the psu and turned it on. This time managed to get on but it took way longer than usual about 10 mins. I built this pc a little over a year ago. The only problem I ever had with it was a software bug that made the colors act weird (This was about a year ago).
