|All the signs your hard drive died or you lost your mbr.|
Can you go into the bios and do a hard drive detect? Does the bios see it?
If it does then perhaps its just the drive is missing the master boot record. Usual sign for this is a flashing cursor in the upper left corner of a black screen.
You would need to get a xp cd and boot into recovery console to run fixmbr and fixboot.
Answers are only as good as the information you provide.
