Is this a laptop or a desktop?
What video card do U have?
Not even bios? Does it write anything on the screen? Any weird noises, lights?
If it's a laptop, remove the battery and only run on cable, or remove battery , hold power button for a few seconds, then try again.
If U manage to get into the bios eventually, U can do a few things with the xp cd.
(maybe change bios defaults ,and with cd : scans, renames, etc)
Write back and we'll see. (Hopefully no screw driver is needed
,just kidding! )
