A handful of computer problems represent most of the service we provide in our shop. Virus and spyware problems are most prevalent. Hardware issues such as hard drive failure and the effects of power surges on power supplies and network cards also are common.
Virus problems can be alleviated by installing a good anti-virus program. We recommend AVG over other widely-advertised brands. AVG does a good job staying current on threats, and does not come with extra “baggage.” Norton, probably the most widely used antivirus, has had to distribute software that enables users to fully uninstall their product. Run only one antivirus at a time.
Anti-spyware programs such as Spybot (spybot.com), Adaware (lavasoft.com), and Microsoft’s Windows Defender are all free and effective. Before downloading, be sure you have accessed the original Web site.
Once you have installed anti-virus and anti-spyware software, regular updates collect information on newly discovered viruses and spyware. After updating, scans must be run to detect issues on your computer. If you are not running regular updates and scans, you won’t have the protection you expect.
Hard drive failure is common, and easily detected by its faint clicking or whirring. A failing hard drive might still be working, but will have occasional error messages or issues with processing. If you suspect hard drive problems, take care to back up files, photos, and favorites. Replacement of a hard drive involves reinstallation of your operating system, which will erase any additions or changes you have made over time. The fix will streamline processes on your computer, but programs you have added by disk or download will need to be reinstalled.
Power surges, either internally or from the external power source, cause many issues with hardware. The first component an external power surge will affect is the computer’s power supply. Power supply replacement is quite simple, and does not affect data or the operating system. Some computers require a proprietary powYer supply which must be ordered at a higher cost.
A good first step is to reset the modem and router by shutting off the box most closely wired to the computer, then the second device, if applicable. Wait a few seconds, then power them up again, this time by powering first the device closest to the cable source at the wall. If a problem still exists, a tech may determine that the network card must be replaced.
Surge protectors can prevent some of these issues, but lightning and severe surges may still get through.
Your surge protector’s effectiveness may be diminished over time by the surges it withstands.
Replacing your surge protector every few years may alleviate repair issues in the long run.
