To repair a Toshiba laptop that is running slowly, try deleting unused programs and defragmenting the disk. If neither of those methods work, expand the laptop's physical memory or, as a last resort, wipe the hard drive completely.
To delete unused programs, click the Add/Remove Programs button in the Control Panel to display a list of all software installed on the laptop. Determine the programs that are used infrequently or not at all and delete them from the system.
Defragmenting the Toshiba's disk moves files closer together. Over time, saved files tend to scatter to different locations on the hard drive. The space between the files causes the laptop to run slowly. By moving them closer together, more free space is accessed and loading times shorten. To perform this task, access the Accessories section of the Start menu and find the System Tools menu and follow its instructions.
Expanding the physical memory of a Toshiba laptop involves installing new Toshiba-compatible RAM cards. RAM, or random access memory, has control over the number of programs that can run efficiently at the same time. To install a new RAM card, open the panel on the underside of the laptop. Remove the old card and put the new one in its place before replacing the panel.
Wiping a hard drive involves deleting all information and returning the laptop to its factory settings. All important information should be backed up, as a hard drive wipe leaves nothing behind. To wipe the hard drive, turn off the laptop and, while turning it back on, press the "0" key to access a menu that allows the deletion of the old Windows installation; reinstall it with the recovery DVDs that came with the laptop.
