How long should I run intelburntest for?

Now that I think of it my card does make a buzzing sound which started around the time I started having the black screen.Although it happens only on start up.

Thats the sound of a dying cap, time to RMA

Thanks I did decide to RMA the card.

No, not always... OP could also have been unaware of the perfectly fine coil whine present in some components, and only realised it was there when he went looking for problems
OP - did you run furmark at all? Did you run anything we said you should?

Ran furmark and memtest,furmark caused the same problem while memtest didn't(no errors detected).

Well I couldn't think of anything else to blame

I had a card with a bulgy cap, a sapphire X1600pro and it made buzz after 3min of 3Dmark2001 benchie...so yeah.
