Troubleshooting tools
Be ready with any eventuality. Keep a set of tools that you can use anytime your PC bogs down. These tools should be placed strategically where you can reach for them in times of need.
You may invest on basic items such as screwdrivers for use in attaching or removing components; needle-nose pliers; tweezers for getting jumpers and hard to reach items; lint free cloth for cleaning and wiping parts; compressed air clears gummed up fans and vents to be used in reviving blinded optical drives and for data connections; electrical contact cleaner solution to improve electrical conductivity and a hand-held vacuum for sucking dirt, hair and other embedded particles.
