No idea what I'very done!
I was playing Portal 2 through Steam when it glitched, the colours went weird and it froze. Restarted and it was fine for about ten minutes and it did it again. The third time it reacted to a YouTube video, so it can't have been Steam. Now when it starts up there are green stripes behind the Windows logo and it directs me straight to the troubleshooting menu, none of which has helped. I can't use it at all. Any suggestions?
