So, your computer's getting old.

Its once-sleek exterior is ridden with nicks and scratches, downloading one song takes a half hour and the B keeps popping off your keyboard. Maybe it's simply time to let it go. But, then again, maybe not.

Buying a new computer is an expensive investment, so it's important to consider some of the factors beforehand: the age of the computer, your personal computer needs (note: a lime green computer is fun, but not a need) and of course, money.

If your computer is more than eight years old, chances are, it's time to move on. An upgrade may be a possibility, but a lot of new programs aren't compatible with outdated systems. In addition, if it's a hardware issue, older parts will likely be more expensive, because they'll be harder to find.

Also, start to assess your own needs. What do you use the computer for? If you use it extensively for work and could benefit from some of the latest software such as video editing, it could be time to consider investing in a new computer. But if you mainly use your computer to check your email, follow Kim Kardashian on Twitter and type up the occasional poem, you might benefit more from a simple quick fix, like virus removal, a memory upgrade or a power supply upgrade.

Another important factor is the cost of repair. If the cost of repairing your computer is nearing the cost of buying a new one, it's probably best to say your goodbyes.

Either way, be sure to take it in to your local Maryland virus removal center for a diagnostic, and take it from there.
