There are some things that just need to be done. Basic maintenance on a computer is one of them. Running a disk check, defragmenting the hard drive, updating software, updating anti-virus software and running scans all fall into this category. The one that everyone seems to forget is dusting (cleaning out) the insides. This isn’t really that difficult, a couple of screws take off the side cover (depending on the design of the case, pull a lever and the side comes off, no screwing around needed).
As an example, this last week I received a call from a client “My computer screen keeps going blank! I turn on the computer and it works fine for about 15 minutes and then the screen goes blank. I can turn the computer off and start it back up, but the screen just keeps going blank after a few minutes.”
