Care of Computer Hardware-
Your hardware can last for the life of your computer if
you keep your computer ventilated (by having a
sufficient amount of fans) and by cleaning your system
every 4 or 5 weeks. Cleaning the dust out of your
computer is pretty easy. Just get a can of pressurized
gas to clean the dust off your internal hardware.
This quick overview should help you plan for hardware
and software obsolescence. Being proactive, can help
you avoid 75% of the hardware failures before they
occur. As to your software, you will need to be the
judge of what you need and want. But as to security
software - that is needed whether you are a consumer or an online marketer. Protection online is always a top
priority in my books.
