my compaq presario 2500 wont boot up

Did you have a two factor authentication or .......... Ran something else.  The issue might be in the registry that removed that dll from the bootup/auth line.

You would need to boot system and have a registry editor to correct this.

You should request attention, as the database topic is incorrect.

after i follow instuctions on the website about pressing f8 and select restore to last working configuration a new message pops up saying this application has failed to start because SHELL32.dll was not found.

What OS? It looks like a very old laptop running XP? Remember that XP has been dead for over an year now, and it shouldn't be used anymore because of the increasing security holes that don't get patched by m$ updates.

Besides, with a laptop as old as that you are likely to start having hardware problems, like the HD failing, etc.

Boot the PC from the UBCD and run the HD manufacturer's diagnostic utililty that is included on that CD. If it tells you the disk is bad, you'll either have to replace the disk, then restore your OS and data from your backups, or scrap the laptop as it really is too old to repair or keep on going. Also test the RAM using memtest86+ which is also included on that CD:
