Well I finally took the old noisy broken graphics card back to the shop I bought it from, it was in its years guarentee, so all fine, they took it from me with no replacement and said they would contact me when they had cleaned it up (suspecting it was just dust). I thought thats ok a few days, i wont bother asking for a replacement of their just going to give it a clean.
I had to call them over a week later because they hadnt got back to me, and I was told, "hang on i'll go see what they did with it" and he says the fan is completely worn out, so i started whining about not having a pc and coursework to be handed in thats on it (they dont know i have a spare graphics card in there at the mo) and he said to get a replacement from them in the meantime.
I went in today and got a piece of
rubbish, half as good as the one i bought, that not only the cable wasn't screwing in right, when we put it the the pc for some reason the power wouldnt come on at all

, but when we swapped them back it worked. There was mass panic for a few minutes though!
Could the crappy graphic card have caused the power not to come on?
Should i annoy these people everyday to get my graphics card back? I was a bit miffed when they didnt call me for a week the first time, i dont want to wait a month for it. He said it would take 2 weeks the first time i went in, for the replacement to arrive.
