keysnottorestore crash

Hey! Dell Inspiron 6000 fully updated BIOS and drivers, WinXP SP3 and all updated here too. Here is my issue: Been experiencing blue screens for a while. Last time there was a bad key in my registry and I deleted it and no more problems (maybe find my earlier post). I started with the same diagnostics that I detailed in my postings on the last issue. This time I find that when I click on the keysnottorestore key in my registry I get the BSOD. filesnottorestore is fine. I can read and touch all entries there. As soon as I click on the entry for keysnottorestore I get the BSOD. I don't have time for all the diagnostic logs and might get to that later. Can I delete this key somehow? Will Windows rebuild this on reboot? any help appreciated.
Cheers
