The author needs to clearly state “Windows computers” - since those of us who run Linux or OS/X don’t tend to have these kinds of problems.
I agree. The problem isn't necessarily the hardware but rather the bloated Windows OS.
I switched to Linux Mint years ago and decided to upgrade my hardware by buying a refurbished HP with the flat form factor rather than the upright desktop style and it has been running constantly since. I leave it running all the time. I did buy a blower from Amazon to blow out the dust every couple of weeks because I live in a dusty area and have 4 dogs that adds to that issue.
I even bought a spare power supply to go with it because I've had many power supply's go bad over the years but so far this one is still going strong (knock on wood).
Electronic circuitry doesn't like dust which can cause shorts across solders spots on boards so I think using the electric blower is better than the canned air which also blows very cold air which can cause a quick thermal variance on the warm board causing damage. I also don't have to keep buying canned air. I pull the cover off the top and blow it out while the system is still running. With canned air I'd need to let it cool for at least 10-15 minutes before blowing it out.
