By chance is the old P4 machine a pre-imaged machine?
Would you happen to have to use restore cd's on it to reinstall?
This could be that there is a CRC on the disc, thinking that it should be in the other PC.. the numbers dont check and BSOD...
Try completely wiping the disk, get a low level formating utility like Data Destroyer or similar, and then attempt to reinstall and see if you have better luck,,
