Do you know the answer to how can i speed up my computer? There are some powerful tips here:

Apply Windows UpdatesIf you run Windows and you use the Internet, you simply MUST stay up to date with the system patches that come out in response to the privacy and security exploits that are discovered every week. Failure to do so is an open invitation to hackers and crackers to invade your privacy and enslave your computer in a spam spewing network. To get the latest fixes and configure your system for automatic updates, open Internet Explorer, click on Tools, then Windows Update.
