Tore down short of MB removal. Didn't see any gross damage on connectors. Hard drive seems to be fully seated. Reassembled, tried all the same install DVD/CD as before. No joy with 7 or Vista. XP got through to the licensing agreement and then hung up.
Tried install with Windows XP genuine disc and got this after the STOP message:
pci sys Address F748EOBF base at F7487OOO Date Stamp 3b7d855c
Will next call priest to perform exorcism on this demon machine! LOL
