So today I was on my computer, when suddenly an orange screen comes up. Nothing got rid of it, so I had to simply restart the computer. But after I did that, all that showed after boot was a black screen. So I used a repair disc to try to restore it to a previous point, which did almost nothing - except now the black screen has a few lines of random pixels for a minute before just going completely blank. I really don't want to have to refresh windows, so does anyone have any idea how else I could fix this?
