In summary, these are the hard lessons people learn because of the mistakes they made on their computers. It could be out of curiosity; it could be out of pure ignorance; it could be the desire to fix something in a hurry even if the user has no knowledge on how to fix the computer; and sometimes it’s just because of plain and simple stupidity. Whatever the reason, let’s hope these hard mistakes serve as a lesson when handling computers.
Not having an antivirus program
No matter how careful we all are with our computers, if you surf the net, chances are something will want to enter your machine and infect it with god-knows what it is. Always have an updated antivirus program. It’s no good if it’s not updated. You don’t even need an expensive one. In connection to this, even if you are running an antivirus program, don’t ever attempt clicking on links and e-mails that you don’t know about or try to click from the darkest corners of the net. These are where you pick up those nasty viruses.
Lifting a laptop by the screen
Doing this can be lumped into the category of ignorance or stupidity, or both. But logic tells us that the base of a laptop is heavier so always lift it from the base. Lifting by the screen will exert pressure on the hinges and will break the TFT-LCD or the CCFL lamp on the top portion of the LCD.
Not regularly cleaning your PC
Dust builds up inside of your PC’s case over time. This dust clogs up fans, reducing air flow, and increasing the temperature inside your PC. A large amount of dust build-up can result in problems with cooling, which could lead to system crashes as your CPU’s temperature increases. Take time to regularly clean out the dust, not only in your PC, but also from your laptop. Canned compressed air is useful for these cleaning tasks. While it’s understandable that we are all busy working, a damaged PC or laptop will render all your work useless.
Not using a surge protector
If you don’t have your computer plugged into a surge protector, you are putting your computer in great risk. Should there be a power surge or power outage, this can damage your equipment. A good surge protector will absorb the power surges and keep your equipment safe. It will also protect your PC against lightning strikes, but in connection with this, it’s always best to err on the safe side and turn off your laptop and PC during a lightning storm. Don’t ever think that just because your laptop is running on batteries it won’t be damaged by lightning. Ever heard of EMP? That’s what lightning can do if it strikes near enough.
Yanking cables out from a PC
Be sure you gently remove any cable that is attached to your computer. Some cables have screws that hold them in place. Some have plastic tabs. If you just yank the cable out, the cable can break or the computer port can be damaged.
