I thought this article at Entrepreneur.com was really useful, especially for someone like me, who’s terrible when it comes to the health issues pertaining to anything and anyone.
1. Delete your deleted items. If you use Microsoft Outlook or Outlook Express as your e-mail program, you have two folders called “Sent Items” and “Deleted Items.” You should go through these files every week, save the ones you absolutely need, and delete the rest.
2. Toss your cookies. Your PC keeps copies of every Web page you’ve ever viewed in a “Temporary Internet Files” folder, while a separate “Cookies” folder contains programs that help marketers track you down. You don’t need these files, and they can take up an awful lot of space. Delete them weekly.
3. Delete your “Temp” files. These are files that end in “.tmp” that Gerstein says can easily be found by searching your computer for “*.tmp.” Also delete them weekly.
4. Reboot your computer frequently. Most people start their PCs in the morning and keep them on all day (and sometimes all night). Rebooting your PC at the beginning and in the middle of the day will recover system resources so the computer will work more efficiently.
5. Defrag, defrag, defrag. When your PC puts stuff onto the hard drive, it does it in random sequence. As a result, you often end up with little bits and pieces of programs scattered throughout your computer’s hard drive. While usually harmless, these bits and pieces can be trouble. Your PC has a “defrag” program that organizes all these pieces of data.
6. Run Scandisk. You should run Windows’ “ScanDisk” program at least once a month.
7. Dust. Finally, you should eliminate as much dust as possible from your computer. At least twice a year, you should:
dust and vacuum your computer keyboard and monitor;
remove the trackball from your mouse and blow out any dust; and
open the computer case and lightly vacuum out the dirt and dust that’s accumulated in the innards.
Dirt and dust tend to make the computer’s temperature rise, which can damage the processor. Dirt can also create short circuits, especially in the power supply.
