I bought my Dell Inspiron 545 desktop about 5 or 6 years ago and never really did any maintenance to it.
What can I easily do to make it last as long as possible?
In the next few days I want to open it up for the first time to try to get all the dust out, ... but what else would be advisable to do?
I've heard somewhere that the most common reason for a desktop computer to die is a faulty or broken fan. Is this true? If yes, should I replace all the fans with new ones?
I've also read somewhere that some computers/chips use 'Thermal Paste' which needs to be replaced every few years. I'm not even sure if my mainboard uses thermal paste?
Is there anything else I can do to extend the life of my desktop?
Many thanks in advance,
