PC Preventive Maintenace and how to do it.

By performing the Preventive Maintenance Inspection (PMI) is to preserve the reliability of the equipment we use. Through careful inspection, cleaning, and maintenance, our computer workstations will perform better and last longer than those that are neglected. The PMI also allows us to detect serious problems before they occur and perhaps prevent system crashes and reduce equipment down time. Preventive maintenance is also periodic in nature. In fact, PMI sometimes stands for Periodic Maintenance Inspection. The period between PMI’s from site to site. It mostly depends on how dirty things get. 

The PC PMI Overview :

It required tools and materials in addition to your computer workstation you will need the following: Soft bristle brush, compressed air, spray and wipe cleaner, cotton swabs, cloth or paper towels, diskette cleaning kit, a digital multimeter, and diagnostic diskettes.

Inspection - Before you start, do a rattle test. Gently rock the CPU back and forth while listening for loose and traveling parts. If the CPU fails the rattle test locate the problem and report your findings to your supervisor. You’ll have to remove the cover of the CPU chassis. If you're not sure which screws to remove ask you supervisor.
