My Dell Pentium (4 years old) is constantly running the fan and putting out hot air.

How long since you dusted it out?
by R. Proffitt Forum moderator / July 29, 2006 1:19 AM PDT

While many were unaware of the need to clean heatsinks and check fans, some machines had failing motherboard capacitors which I had the displeasure of finding in our office desktops. These caused increased power consumption and excessive heating. Link with pictures at http://www.badcaps.net/

After cleaning, there is a non-PC-Hardware issue of spyware and pests. Some will cause a machine to run at full tilt. Today I suggest we scan with EWIDO and HOUSECALL (google.com please) and toss what those scans find.

You're house cleaning may be impeccable but your PC
by VAPCMD / July 29, 2006 1:59 AM PDT

is like a vacumm sucking in unfiltered air and explelling it out the rear. Problem is some of that dirt and dust accumulates on components inside the case making them less efficient at cooling the PC and making it run faster to expel the heat. So, get out your system manual, remove the ac power, open the system case, and perform a little house cleaning. Once it cleaned out, reconnect the AC power and run the PC with the case open to make sure it works and see how it sounds. If OK...close the case and enjoy.

Let us know how it works.

PS...We won't tell anyone about the dust you found

Susan Davis might wanna dust her cpu cooling fan. its probably coz that dust gets acumilated between the heat sink gaps. so heat does not completly get disipated tho the fans are running.The fan also might be running slow.Try dusting the fan and if that does not cool the CPU then try replacing the it.

To test the idle speed of the fan blow on the leafs of the fan and see how long the fan spins freely....if its in a good condition then it shud spin for more than 2sec without any vibration or noise.

How much percentage of the CPU is being used wen its idle?

I shud warn u that static electricity can destroy the components of the system, so be sure to discharge urself wen touching the CPU or other components.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
