I was playing a game and it crashed and couldn't move anything on the screen so I restarted my PC. When I did this, the screen looked messed up with some lines and missing text when the PC is starting.
Now I can see pink/purple vertical lines; small in length but there's different rows of them.
I tried a different monitor and I get the same thing. Normal windows mode wont start as the screen just goes to standby after the Windows Welcome screen.
