You may be running too many programs in the background which can heat up a processor pretty well. You may also have a virus which overtaxes a processor. Also, always make sure that the heat vent in the back of the pc is well vented and not obstructed, and NEVER have the pc placed on something like a bed, blanket, or pillow
OK, Do this;
These are the steps that you need to take, and the instructions on how to do it:
1. Reboot into Safemode
2. Run a virus and spyware scanner while in safemode
3. Defrag
4. Scandisk
5. Registry error repairing while in safemode
6.Reboot into regular mode windows

Here is how to do it:
Reboot yor machine while holding the F8 key right as it boots back up. A menu will apear. Choose -->"start windows in safe mode with networking".
Windows will start in safe mode. Run an AVG virus scan, then run Defrag by exploring your computer, right click on C: drive, click PROPERTIES, then the TOOLS tab, click the "check now" button, and only checkmark the top box 'fix file system errors', then click ok, the computer will then tell you it will scan upon next reboot., Now click the DEFRAG NOW button. the choose defrag. After Defrag runs for about an hour and it is finished, restart the system. If is still won't run normally, go back into Safemode buy pressing F8 on reboot, then run a registry fixing program such as uniblue registrybooster, then reboot again. If it still won't run right, you may want to reinstall Windows and see if that works. If reinstalling windows doesn't fix it, it may be a hardware problem.
Good luck.

Fan runs alot and the laptop over heats and shuts down


keep your notebook well ventilated (there are vent grills at bottom that ned to be kept ditanced from the notebook to the flat hard surface where you place the notebook. Also, try to clean the fan , by removing bottom cover : use air can to blow away dust - clean the fan. If the system has never been cleaned before, i can assure you there is mounds of duct inside , especially on the fins of the heatsink fan that cools your CPU and video card. I would also suggest getting air compressor to blow away the dust , if there is too much of it inside. YOU MAY HAVE TO REPLACE THE FAN unit . You can otherwise , go to teh BIOS set up nad reduce the fan speed.

My HP Pavilion dv6's fan seems to run in overdrive constntly and the computer still overheats. Please help

Hi lukergrt, There are a few things you can try. First, see if your computer and fans are really dusty - dusty computers get hot fast. Clean out the fans with compressed air or a dust buster. If you're comfortable opening up laptops, you can clean even more dust out from inside (disclaimer: ONLY do this if you're experienced with laptops, otherwise a cleaning from the outside is fine). If you're still having issues after that, look into a fan pad for under your laptop. Something like this is fairly effective at keeping your laptop cool. - Good luck! Alex

The fan seems to be running hard and loud. i have cleaned the system and it's running quieter since then. is that normal for the system to do?

I'm assuming that when you say you cleaned the system that you mean you removed programs, old files, viruses, etc.
If your computer is set to change fan speed based on how hot the processor or video card gets, which it probably is, then more programs and stuff running on the computer would cause your hardware to work harder, get hotter, and need more ventilation. Thus faster fan speed.
However, I believe what really happened is that dust collected on the fan(s), causing them to make some new noises and then the dust fell off because it was so heavy or it got sucked through the fan and out of the way finally. Which means it was a coincidence.
Now if you meant that you literally cleaned the computer (opened it up and blew all the "dust bunnys" out) then yeah it makes perfect sense that it would be come quiter.
By the way, if you have not opened the computer case and cleaned out all of the dust, you really really should.
Disconnect the computer from the outlet, open up the case, and using a can of compressed air (about $5) blow out all of the dust, hair, and dirt to make sure your hardware stays in good condition.

My Acer Aspire 5735z constantly runs hot at around 65-70 degrees celcius. It runs very hot even when i'm not doing much. Watching a movie or playing a small online game makes the computer go into overdrive...

Have you replaced the heat sink thermal paste?
Also the fan blades may look clean, but have you removed the fan and checked the outlet grill that the fan blows through, it gets clogged with fluff, dust and hair etc.

The fan is constantly running and part of the laptop gets really hot

Check the vent where the fan should be blowing out hot/warm air for good flow. If you don't have any air flowing, you might find that the fan inlets are plugged with dust, or the fan blades are covered with dust/fuzz. Clean all the air passages, inlets and outlets to make sure the fan can flow enough air to cool the computer.

I recently had a new power supply installed in my compaq presario SR1318NX, now the fans run almost constantly. The air from the fans does not feel hot, nor does the tower. Is this serious?


In a desktop computer the fan is supposed to run constantly otherwise the processor would get that hot the system would repeatedly shut down or even damage the processor or motherboard.

If the fan is noisy then chances are that the fan blades need cleaning of dust.

Other than that you have nothing to worry about.

My fan makes so much noise especially when i play video.Can someone help

The problem with fans is there really isn't much you can do with them. Normally they begin to make noise as the bearing assembly begins to wear, or it might just need to be cleaned. In either case you need to crack open the case on your laptop, then you can inspect the fan. You can try cleaning it at that point, but usually its easier just to replace it. The reason why it makes more noise when you play videos is because video media requires more system resources to run, which also generates more heat. So, while you have your laptop open you may want to check your video card (which should also have a fan) and make sure that its clean. A dirty video card will **** out a lot earlier than it should.

My laptop fan constantly runs help!

First, I recommend cleaning all the dust out of the cooling vents. Use an old toothbrush to brush the dust away from the vent holes and blow air through the vents using one of those compressed air cans made for cleaning keyboards. One time I worked on a Sony laptop that I had to take apart to get all the dust cleaned out of the air vent.

The second thing I recommend is to download a piece of free software called FanSpeed. Here's a link
I'll let you read the description for yourself, but in short it allows you to monitor the temperature inside your computer and to adjust how the fans react to this temperature.

Loud fan, monitor blinks & goes black

The fan can be cleaned. You may want to take it into a computer repair store and get it done as well as inspection of it. Noisy fans are caused by dust in the bearings. In most cases, this can create the noise since the bearing are being grinded down.

Laptop overheats way too fast...

What is the model number of your machine? Some have design flaws that make them run hot. Also dust is a great insulator. I would take the machine into a repair shop or get a can of compressed air and blow out any fan areas. A laptop cooling pad can be a good idea as well especially if you notice that the machine overheats while sitting on a desk. The noise of the fan is probalay due to the dust coating the heatsync. The fan has to run much faster to move more air to cool the system. Blowing out or having the heatsync cleaned is a good idea here!
