Windows 8 Black Screen Of Death?

Well, the other day I found a game that I used to love from 2001 and I put it in my computer, and it starts up fine. But while it was loading I tried to alt+tab out of it to do other things while waiting. But instead it gives me one of those half game half main screen things. Where the task bar is show while the game is still on screen, but doesn't work to open the windows etc. so I tried to use task manager and it wouldn't work because of the glitches screen.

So I thought maybe if I restarted my computer it would go back to normal. But no, instead I get a (different) version of the "windows 8 black screen of death" thing. Instead of the blinking screen and stuff, the computer would turn on normally and show the hp logo (hp pavillion g6 btw) but after that, nothing. No cursor, no blinking, just nothing. Except when I press escape when it boots up, I can get into bios and stuff fine. So I tried to put my restore cd in there to try and "boot up" from it as most sites called it, and nothing. Or is it just my computer dying ( which it shouldn't be because I got it April of 2013 )

Also, sometimes when I boot it up it will go straight to the "windows automatic repair" screen with the logo, but it will sit there for maybe a minute or two and go back to a black screen
