Being the family IT guy, the question I get most is about how to fix a slow computer. There are lots of reasons that cause a Windows machine to grinds to a halt, but typically the owner has never taken steps to maintain the machine. Over time, old programs may leave unnecessary files and registry entries that gets in Windows' way when trying to complete normal tasks. In some circumstances, malware, spyware, our even viruses will significantly slow you down. The tips below should get you back to a speedy operating system.
1. Uninstall Unnecessary Software. Go through the entire list of installed applications and windows Add-Ons and remove any that you never use.
2. Review Startup Programs. Some programs are designed to open when you start your computer. Unfortunately, if too many open up at once, things will slow down. Review the programs listed under the "Startup"folder in your programs listing. You can right-click and delete the ones you want to prevent from automatically opening. If you are feeling adventurous, Google 'msconfig' and read up on some advanced methods to gain more control of which programs and Windows services are executed during the boot.
3. Run Windows Update. Be sure to keep your system updated with the latest security patches and optimizations from Microsoft.
4. Check for Viruses and Other Malware. Run a full system scan using an up-to-date virus/malware scanner. Check out Microsoft's Security Essentials for a great, free option. If you find something bad during your scan, I recommend reinstalling Windows (see below). Is this a pain? Yes. But, it is the only way to guarantee that you have gotten rid of your problem since removing these things may cause your system to become more unstable than before.
5. Defragment your Hard Drive. Over time, the data on your hard drive will become fragmented and spaced illogically across the disk. This us especially the case if you delete our move lots of data like pictures, movies, our music. Use the built in Windows defrag program...it is simple and gets the job done. If you want more options when defragmenting, Google 'My Defrag' and take it for a spin. Note that defragmenting does not work on solid state hard drives.
6. Reinstall Windows. This isn't the easiest option, but it is the one thing that will definitely get your computer back to the days when it was really fast. I typically do this once a year to keep my machines in tip-top shape. I'll post my how-to on this soon...in the mean time, gather up all of those installation CDs that came with your computer (you still have them, right?). Be sure to back up all important files before doing this...your hard drive will be wiped clean!
Remember: Backup all important data before making any major changes to your computer!
