Uninstall Windows, then format your HD, and reinstall Windows. Your PC should be quick for an hour or so before you need to repeat.

We say - An hour? You must visit some very dodgy websites, Mr Me! Although this tip was probably submitted as a joke, there is some truth in what this anonymous contributor said. If you don't look after your PC, by keeping out viruses, spyware and other malicious software, it may reach a point where reinstalling your operating system may be the quickest route to a healthy PC. Of course, there is no need to uninstall Windows if you plan on reformatting your hard disk and starting from fresh, as formatting will remove all programs and data on your computers hard drive anyway.

Some Windows users recommend that you reinstall Windows about once a year, but we only recommend doing so if you have severe problems with your computer that cannot be solved any other way. If you do decide to reformat, make sure you backup all your valuable data first!
