Fans: Check the power supply fan for airflow and the
processor fan for movement at least every six months. Take the case
off of the computer and turn the computer on to check the processor
fan. If one of the fans stops while the machine is on, you'll need
to replace it immediately to prevent further damage.
Computer Case: While the computer case is off, use a can
of compressed air (available at most office supply stores) to blow
out the dust. If you want to save some money on compressed gas,
remove the cover(s) from the computer and go to your nearest gas
station. Blow the dust out of the computer case with a blow gun or
tire inflator. We use an automotive-type compressor and blowguns to
clean equipment at our shop. (Only blow dust out of the computer
case, not your PC's innards.)
One caveat: If you are using canned or compressed air, use short
bursts to avoid condensation.
Drives: Clean the floppy drive(s), CD drives, and tape
drive to help prevent errors during use.
Clean with
either Simple Green or 409 spray. Be careful not to get the
insides of the drives wet.
Tape drive: If you have a tape drive, you may be able to
clean it by using a long Q-Tip dampened with rubbing alcohol. Open
the door and clean the rubber pinch roller and head located inside.
If you have a DAT, SLT, or DLT drive this may not be possible since
the pinch roller and heads are too difficult to access.
