but if its system instability or windows/virus issues, then he could be wasting money for nothing. personally i would have a go at resolving a problem rather than ditching it and shelling out money.
Given that his problem is to do with ATIKMDAG.SYS, with which there have been numerous well documented problems going back several years, the chances of it being anything other than the ATI drivers are remote.
He's already stated that it does it with everything at stock, so instability is unlikely. As for Windows/virus issues, a full reinstall of Windows with the bare minimum of drivers/software installed would test that but I presume he's already tried that.
