Intel D975XBX mobo
Intel Core 2 Duo E6400
Transcend 1 Gig (2x512)
Powercolor Radeon x1950xt 512 pci-e
Western D. 250 gig. SATA HD

Everything is brand new from the box.
When i try to boot a fresh copy of XP Pro,
it'll load all the setup files,
but when the actual installation starts,
(when it says "Starting windows setup")
it'll just go to a blue screen error message saying

Stop:oxoooooo7e (oxf78e8208,oxf749cobf,oxf78e8208,oxf78e7408)
followed by "pci.sys - address.........blah blah"

or a black screen with "media error" and something about cables.
though i've gone over connecting cables and wires
in the right place over and over again to no avail
can someone please help,
p.s. i've also tried 2 XP cds, no change either
