While the possible causes of system slowdown are endless, this article identifies 10 common troubleshooting areas you should examine before you consider drastic steps such as reformatting and reimaging or buying new computers.Chipmakers have recently been working to make processors more efficient, which means they generate less heat.
That's why all processors require some sort of cooling element, typically a fan of some type.Windows 7 has been out for almost a year, and the PCs you bought right after its release may be slowing down now.User complaints are minimal when new PCs are rolled out.They start up quickly, and programs seem to open in a snap.But over time, users begin to notice that their systems are slower or hang up more and more often.A system's Thermal Design Point (TDP) rating indicates, in watts, how much heat it can safely dissipate without exceeding the maximum temperature for the chip.
When the processor temperature goes over spec, the system can slow down or run erratically (lock up) or may simply reboot.
The processor fan may fail for several reasons: Often, you can tell if there is a fan problem by listening and/or touching the computer.
A fan that has loose bearings starts jiggling and vibrates the case, making a characteristic noise.
As time goes by, the sounds and vibrations will become so prominent that you'll change the fan out just to regain some peace and quiet. If it is covered with dust, you can often spray away the dust with compressed air.
But even though you might get the fan running again, its life span has likely been reduced because of the overwork.
You should keep an extra fan in reserve in case of failure.
