When problems occur, first reboot your computer.  This solves many problems.  It is also wise to reboot once per day.  This helps Windows manage computer memory.  Turning off your computer once per day helps minimize internal dust accumulation and saves electricity.  Also, turn off and then turn on your Internet modem and/or router if your Internet connection is disrupted.

Do a full data backup at least once per month, and more often for critical data such as photographs and financial information.  Keep the back up media in safe places, such as fireproof safes, safe deposit boxes, or at a bare minimum, off-site from the location of the computer.

Do perform a weekly or monthly tune-up of your computer’s hardware and software, including a disk cleanup, scan, and defragmentation; and updates and scans for viruses and spyware.

Do not smoke, drink, or eat near your computer.  At least once per year, open the computer case and either vacuum or use compressed air to remove dust from the inside.

Do keep nearby copies of all CD’s, serial numbers, and registration numbers for all software and hardware that came with the machine and that was purchased at the store or downloaded.  Also keep all installation instructions and manuals for using these materials.

Do not delete files or folders from your computer that you did not create.  It is safe to delete shortcuts to programs from your desktop that you do not use.  These are indicated with a small curved arrow in the lower left corner of the icon.

Do keep a copy of your current Internet Service Provider (ISP) information.  This includes telephone numbers for customer service, technical support, and dial-up access; user names, addresses, and passwords; and mail server names. 

Use the System Works and Internet Security programs from Norton and McAfee sparingly.  These programs often cause more problems than they solve.  Instead, be sure your Windows Firewall is turned on or obtain a free firewall program such as Zone Alarm at www.zonealarm.com.  Also, obtain Norton or McAfee Antivirus (usually free or next to nothing with rebates if purchased between October and December of each year), or obtain the free AVG Antivirus from free.grisoft.com.

Do your utmost to keep you computer free from Internet intruders.  Do not open unsolicited email.  Do not open attachments from people that you do not know.  Do not go to web pages offering free and fantastic deals.  

Do not purchase floor models at retail stores. Do not buy refurbished equipment unless the price is much less than the new equipment.  The price of computer equipment decreases so rapidly that it is likely that new equipment with the same capabilities will be available at a lower price within a year.  Lastly, you are usually better off without the extended warrantee.  Be sure the equipment comes with a one year manufacturer warrantee.
