Tip & How-To about Computers & Internet

Keep your PC cool

A common reason for a PC or MAC to run hot is the buildup of dust around the power supply fan. Cleaning this typically required opening the case and carefully brushing away the accumulated dust.

Simplify the cleanup using old pantyhose. If you're not the panty hose wearing type ask your wife, GF or that slightly different neighbor.

Cut a piece of the nylon and slip it over the fan guard (which can usually be removed without opening the case. Periodically check the nylon and clean as necessary.

Acer Radiator fan will not shut off PC Desktops


LOL, some fans will not shut off, this is normal in some case. But, to be sure your system is not running real hot to keep the fan running try this:
Remove the Power Cord, Remove the Case and take a can of compressed air and blow out dust from the computer's vents and all inside the computer. Also blow out dust from around the power supply and fans.

If it still runs all the time you can remove the fan that sits on top of the cpu and heatsink and clean the dust and apply a fresh coat of Thermal Paste to the CPu and HeatSink.

hard drive is very hot and sounds stranges


Hard drives typically run pretty hot and have a cooling fan to make sure they don't overheat. The fan vent are easily clogged with dust that can build up to make the fan almost useless. Power off the computer and let it sit idle for about an hour and unplug power cord then open the case. Carefully brush away dust that has accumulated inside the case, making sure to clear the vents around the harddrive and the power supply. If the harddrive continues to make strange noises, I would strongly recommend making a full backup and get a new harddrive ready. When it comes to harddrive crashes it's not 'if' but 'when'. It will eventually crash, and true to 'Murphys' Law' it will crash when you most need it.

Complete PC shut down whilst playing CD-ROM games


For sure this is an overheating problem.

It's possible it's a fan. First check and see if the fan is in fact running. To do this just put your hand in front of the fan and see if you feel any air. Also there is a fan on the power supply. This fan is usually at the top left of the case when looking at the back of the case. You should also feel air coming out of this fan.

Another possibility is that a filter is clogged or the computer has dust inside of it. To fix this unplug the computer from power and remove all connections on the back panel. Then open the case and clean out any dust. This can be best done by using some portable air. You can find this at Radio Shack, Office Depot, Office Max or almost any computer store. Just ask for a can of air to remove dust from a computer. When the computer looks dust free reassemble everything and try again.

A third possibility is that the power supply is going bad. This would require a replacement power supply. This would need to be done by a computer repair facility. Often compaq uses custom parts so you probably have to buy a power supply from compaq. Power supplies get very hot and can fail.

Hope this helps.
