Tips & Warnings
If you are unable to access the Start menu, use the recovery CDs that came with the computer or visit Acer's website (see Resources below).
Always make a back-up CD before restoring a computer to factory defaults.
Resources
Acer Website

Take the original "System Restore" set of CDs that were shipped with your computer, and use them.

If you cannot find them, telephone ACER, and order a replacement set of those "System Restore" CDs. Probably $20 plus $20 for overnight-courier delivery.

First, make sure that there aren't any discs in any of the drives. (I don't suppose it comes with a floppy, but if it does, make sure that there is no disc in it.) Acer's usually don't come with restore cds, instead they use a recovery partition, which you can access by holding alt and F-10 immediately after powering on. This process will restore the drive to the factory condition, which will destroy whatever newer data is on it. (Good thing you've been backing up on a regular basis, eh?
