If your computer is experiencing problems when starting up and you need to recover your important files then one viable option is to boot and run Windows XP (albeit trimmed down) off a USB memory stick. This process involves using a host PC to install Windows XP onto a memory stick of up to 2GB and will work on most modern PC’s and laptops that support USB booting in the BIOS. This method is particularly useful if you have a netbook or a device with no optical drive or testing a computer with no hard disk.

Good PC maintenance involves a number of different jobs, from keeping your keyboard and mouse clean, to cleaning up your hard drive by removing temporary files. The frequency of the maintenance will depend on how often the computer is used. Basic maintenance, such as wiping over the keyboard and the screen should be done as often as possible, at least once a week for computers that are used daily.
