Trap 00000006 Exception - Compaq

HI! My uncle gave me his old Compaq for my kids.. good computer for what they need it for. It was working good, had a lot of junk on it.. cleaned that off and was trying to reload Windows XP to help with a few little bugs.

Tried to reinstall.. all was going great and it rebooted and suddenly came up with the Trap error.. I tried the Compaq recovery disk.. it says "Call Compaq Support" it won't let me do anything..

HELP! How can I get around this "Trap" screen?

Any help is appreciated! Thanks! Jen
