Hardware Tips

Optical Mice

Over the past few weeks, it seems that a large share of my clients were still using older, mechanical mice (the one’s with the ball underneath). I say older because almost all new mice are optical mice…either infrared or laser. These mice replaced the ball rolling against rollers in the mouse housing (that could quickly become dirty and cause erratic behavior of your pointer) with a light source that tracked your movements more accurately than the mechanical mouse ever could.

In addition to tracking better, never getting dirty, and having the ability to work on any surface (except glass), optical mice also allowed smaller chassis and helped propel a new plethora of cordless mice.

Lots of RAM upgrades lately

The past six months or so, I have performed at least 4 RAM upgrades per week. RAM is the temporary memory that gives  our computers the best chance to perform at optimum speeds. I am doing more of them because folks are electing to hold on to their older computers instead of buying a new one. With the RAM upgrade and some other optimization, most folks can get another 2 or more years out of an existing computer.

When I get a call from a computer user telling me that their computer is slow, it usually needs one or all of these three adjustments:

  1. RAM upgrade
  2. Startup optimization (other articles on this topic)
  3. Less problematic (and free) antivirus/security software like AVG or Microsoft Security Essentials

Adding RAM to increase computer speed – Video Tip

RAM is the temporary memory that the computer uses to give us the feeling of programs opening and running with some pep. It’s like giving your computer a larger desk to work from so it can spread out and find things more efficiently. RAM also allows us to open multiple computer programs at the same time with less impact on the speed of the computer.

256 megabytes used to be a lot of RAM. Today, I’m recommending users have at least

Modems and Routers need air too

I talk and write a lot about making sure that your computer has plenty of ventilation around it so it won’t over heat. Computers suffer greatly when exposed to too much heat. That same principle, however, also applies to high speed cable and DSL modems and routers we use to share those high speed connections. If you examine one of… Read More »Modems and Routers need air too

When you replace an old computer, you need to take steps to protect the data that was on that computer prior to donating it, selling it or even throwing it out or recycling it.
