|Dunno what bios update has to do with sp3, Dunno what ram has to do with it either.|
I guess I'd download the sp3. I'd reload xp to whatever you have to make it like it came from the factory. OEM restore with disks or partitions. Then use the usb file of the sp3 to update directly.
1/3 of highway deaths are caused by drunks. The rest are by people who can't drive any better than a drunk.
