Personal Computers, most commonly referred to as PCs, are like people; they have health issues, which when ignored can lead to malfunctions, and in rare cases, failure. The most common issue for PC or a Laptop is the dreaded Blue Screen of Death, which can be abbreviated to BSoD!
Failing health of a computer can be noticed in a number of ways; such as processes slowing down, programs or applications hanging or freezing and crashing. Computer users that regularly perform time consuming tasks know the feeling of terrible loss if the program they are using suddenly crashes on them before they were even able to save their work for the very first time.
To avoid catastrophic failures; a computer must have a regular check-up in order to avoid costly repairs / recovery costs.
