Windows 7: BSOD + black screen white cursor + can't go to system repair

So I think I'm screwed.

I've searched the forum, I've googled and tried lotsa stuff.

Ok, first I was facing BSOD. So I tried going in by every type of safe mode,
But it doesn't work, I just go to a black screen with moving cursor and I can't
Open the Task Manager.



So I tried system restore, failed with the CD. Then I tried the Grub4dos thing
It failed as well. It just brings me to the black screen with white cursor.

Also when I start in safe mode, it stucks at classpnp.sys and after awhile
It goes to BSOD and reboots.

By the way this all started when I installed a game, Dishonored.

Thanks, please help me! I got this prob on two laptops. And one is my dad's!!

Edited: the BSOD is 0x00000ED
Both are toshiba.

BUMP
