I have RMA'd a graphics card and have received an email back saying that the item is fine.
The problem is that the card black screens (no video) after approx 20 mins to an hour and i am not sure if it has been tested for that long. The card does the same thing in three other computers and i have also tried other cards that are exactly the same (as i bought a few) and they work fine which rules out the PCs and pretty much identifies the card being at fault.
Just wondering where i go from here as it looks like i am stuck with a faulty card.
Thanks
