CPU Fan Speed problem

There's an problem with my machine. the fan accelerates, then slows, accelerates, slows, etc, it also occurs even if the computer is idle.

:thumbup1: Please Help!

What machine do use? Desktop or laptop..?'

It is a desktop as the following Specification.....:

Motherboard: INTEL BOXDG43NB
CPU: INTEL|PDC E5200

Is anything else to be known by your side???

Some motherboards have a varible speed fan control option. You can find it in the bios settings. I normally keep it off (which is the default setting). Could be yours, if you have this, get enabled somehow.

I've tried enableing/disableing the fan features in the BIOS already--nothing. The machine is less than a month old so there is absolutely no dust, etc. Any other ideas?

wat fan u use?? in CPU or a fan case. Is it connected to the motherboard, which fan connection on the motherboard, you might try a different one, you could connect the fan to the power supply. Some case fans have cables to conncet to three pin or four pin connections on the MB and most have a conncetion to match up with the connection to the hds or cds,

Free up PC resources and its memory

The first and most usual reason your PC is slow is because there are plenty of processes, services and applications are running in the background that are not required and some of them you are not aware of, thus taking up much resources and memory that you even don’t have! In this case when your PC do not have enough RAM to store the data Hard disk is used as a memory place to store the data thus greatly slowing up your PC.

1. Verify how much of RAM your computer uses:
This can be done by hitting Ctrl, Alt and Delete simultaneously. When the Task Manager window pops up, bring up the Performance tab and take a look at the Physical Memory section. You will see the total available as well as currently available values. Below on the screen shot you can see the current memory in use (503 MB) and total memory about 981 MB.

If the current availability is less than 30%, usually a memory upgrade would be recommended. But generally speaking if you are running Windows XP your PC can run with 512 Mg of RAM, but minimum recommended to have 1G (1000Mg) of RAM. You also can see the total available memory by clicking right hand button on My Computer and then going to Properties and looking in “General” tab.
Now you know how much RAM you have and whether or not you need to add more. You can add it later on. (we will talk about it later on)
The next thing we need to free up PCs resources and give it some air to breathe so that we can work with it much faster and do some cleaning processes.

2. While you are in the Task Manager, you can as well bring up the Processes Tab then click once or twice on the User Name tab to group all processes that are currently running. You can end any processes associated with unused applications. This will end unused applets and free up system RAM.

Also see if there is any process that uses much of the CPU by looking under the CPU tab and end it. However, be sure that you do not end any System processes as these are mostly essential for Windows to run correctly. It is a temporary solution to free up the RAM and also when you want to forcefully end any process or application that just won’t go away when you want it to so you just turn it off this way through the Task Manager. However when you restart you PC most of these processes will be turned on again.

So how do you turn them off permanently?
Simply bring it up by typing MSCONFIG in the Run tab of the Start menu. You can then easily manage the services and applications that automatically start on boot up. This is found in the Startup tab.

Simply deselect any applications you don’t use on startup, click Apply and go to Services tab.

Select “Hide all Microsoft Services” and unselect all services that are shown now. Leave only those services that you recognize and really need. Click OK and restart your computer (it will ask you to do so).
After rebooting your PC you will feel that the speed is greatly increased! But we didn’t finish yet! There are few more steps to eradicate the slowness of your PC.

Thanks it worked a lot !
This is very much Helpfull for Everyone
