Yup my graphics card seems to have stopped working. Started off with running games causing flickering and slight screen corruption before freezing the computer up. After a few rebooting the screen just looks all corrupted and nasty with "graphics card information missing" errors and the card itself lasting as stopped and not starting up. Tried everything to fix it, updating drivers, installing and reinstalling, reconnecting the card, trying to reset the BIOS but no dice.
Orginally rebooting a few times would restore things but now it seems the corruption/errors are perminant.
Good thing is I have a laptop on hand so I'll still be around at least, through a new desktop is going to be a pain to save towards what with circumstances etc.
