Unfortunately, upon booting up Guild Wars it says that there is a hardware malfunction, so I can't even get past the sign-up screen.
I don't have memory issues and have a Radeon 9800XT.
I've played Vanguard, Warhammer Mark of Chaos, GRAW 2 and many other PC games in the last couple of years and not had a problem.

Does anyone know how I can fix this, rather than putting the game on ebay?
Thanks
