Dirty Computer

Heat Makes Computer Freeze

I hear that lament almost daily My computer freezes. Computer freeze is often caused by exactly the opposite.

Try to guess for a moment what is the most common threat to your computer? Believe it or not heat ranks high among threats to your computer. Running computers generate heat. They are cooled by heat sinks and fans that work in concert to cool your processor from harmful heat. These cooling systems are marvels of tiny handiwork that bring in cool air across a heat sink much like your cars radiator. It then blows the air out to keep things running cool. Several things get in the way of this process.

#1. Broken Fan. Many computers will simply not run if there is a faulty fan. They will even alert you that a fan is not working at start up. Other systems will allow the computer to run but will automatically and abruptly shut down when it reaches a predetermined temperature that the computer considers unsafe. Some will just keep running until the failure messes up the boot up and your computer shows a file corruption and it just won’t start.

#2. Covered Intake. This is caused by placing a computer in a location where it is not allowed to take in fresh air or little fresh air is available like a closed cabinet. All too often a laptop overheats while using it on your lap because a knee or thigh plugs the intake and the computer overheats. (Seems ironic they call it a laptop since your lap can actually ruin it. Some manufacturers call them notebooks for this very reason) Running laptops have been known to start fires while left on a bed while being unable to take in fresh air from underneath.

#3. Dirty. This is easily the most common reason a computer overheats. The cooling system continuously pulls in fresh air with its airborne dust. Eventually tens of thousands of cubic feet of air blows into the computer. Overtime this sucks in enough dust to clog the system. Computers must be cleaned regularly to keep them from overheating. Twice per year on average is about right. Blowing out your computer thoroughly is critical.

There are clues that will tell us our computer needs cleaning. Much like a vacuum whines when you cover the intake so will a computer. But the change is subtle and gradual. Many computers have various fan speeds that ramp up when over heated. If you notice fans running louder or faster than they used to it may be the last warning sign before disaster. When a computer freezes up or is unresponsive it is often caused by excessive heat.

If your computer has run everyday for a year I guarantee it needs a physical cleaning.

Few things kill a PC faster that heat.
