Hi i've been trying to istall windows xp on a pc. The setup was going well until the part where the XP beggin to copy their files on the disk. There i got a blue screen with a PFN_LIST_ERROR. I searched the web and i found that it might be the memory so i changed it but now i got another blue screen with DRIVER_IRQL_NOT_LESS_OR_EQUAL USBPORT.SYS. Could it be the motherboard or something else?
