hi guys, i just brought a new system that i put together myself.. the parts are: motherboard: gigabyte ga-k8nxp-sli cpu: amd athlon 64 3500+ graphics card: gigabyte rx300-se 128mb ram: geil value 1 gig kit - 2 x 512mb hard drive: western digital 160 gig sata drive with 8 mb cache got cd rom and floppy drive now this is my problem, when i install windows xp it completes and everything seems fine until it reboots, after the gui windows xp pro loading screen it goes to a blue error screen and it says registry error, something about not being able to load a system file from the hive (file) it's racking my brain, plz does anyone know why it does this?????
