|I believe Toshiba has a restore partition on the hard drive. Look at the link below to see if they are of any help.|
Or possibly try Alt + F10 at start up.
Watch the screens when the computer is first started to see if there are instructions on what keystroke/s to use for a factory restore.
Keep in mind that this will delete everything you have saved or installed since you have owned the laptop. So backup those items first.
After performing a factory restore you may need to download any missing service packs and/or updates. This process may also allow you to make a set of disks to perform the factory restore if the hard drive were to fail.
It appears that laptop came out in 2004. The restore procedure for Toshiba may have changed in 2007. So, there may or may not be a restore partition available.
