Having problems with your PC Desktops ?

Emachine t2862 fan keep turning on and slows down my computer not sure if its the video card but thats when it usually happens


Answers :

A fan turning on IS protecting something from OVERHEATING, more than likely the pc needs to be cleaned on the inside (blown out) especially the fans..
\015\012If the fan is coming on while the computer is being used, it's trying to cool down a hot component.
\015\012a fan should not strain the system,
\015\012this can be caused by adding a high end video card and not updating the power supply to needed voltages.... but from the factory, the power supply should be more than enough to run the system and fans without getting overused. sooooo........
\015\0121. pull the side off your computer
\015\0122. listen to the fans as they run
\015\0123. inspect them physically for dirt and freeness
\015\0124. check the powersupply, videocard, cpu and case fans..
Hi! there, well test run in every parts, you should have a spare parts or another pc,in your case since you mention that your power supply was good,try to disconnect your hard drive,your cd room and floopy,try to run with your memory and video card only,posibble if you have multiple memory card disconnect other just leave one memory card,switch on your pc,observer if will open your screen,if ok your video card is good,if not change another memory card,isolate checking of memory card w/c is good or bad.if non of the above is good,try to use another part w/c not came to your PC video card and one pc of memory card w/c you assured that are good one,put it on then swtich on if screen open,*********** board abd psu id good,so replace the video card using your video card,if screen open one of your memory is bad.or test you vidoe card and memory card to other pc if good,*********** board or psu has problem,so swtiching of parts is to test is better other tha you just dought.take all necessary precaution doing this to avoid shock,this should be than by qualified pc tech.
