Graphics card died?

[Vanquish]

Ah thankyou all for your help! Tempest I did as you said and the problem is now fixed, thankyou.

Jamz, really you are too kind of a human being. I wouldn't want to impose on you like that, your offer is extremely generous however and I am appreciative. The problem seems to be fixed for now anyway, so it looks like I won't have to buy a new one!

Thanks for your replies! :)
