Overheating When the CPU overheats then it will shut down (i.e. thermal overload) and won't boot up again until it has cooled down. If this is the problem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are clogged with dust.
Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged with dust the remove the dust and make sure the vents are clear and dust free. Use a small brush and can of compressed air to do this.

The cpu fan is running to fast but every thing are ok even boot to windows it's ok. only the cpu fan is running to fast and making a noise sound like a exaust of an amplifier.

The heat sink may be clogged with dust and ifthe BIOS temperature sensor controls the fan speed then it may be compensatingfor the reduced cooling by the dust build-up.
If you are not using your laptop on a flat surface, it may beobstructing the cooling vents on the bottom of the laptop. Your laptop fanmay be faulty and not spinning freely, in this case replace the fan.
Check the fan and heat sink assembly and remove the dust, loosen the dust anduse a can of compressed air to clear away the dust. A laptop fanassisted cooling pad may solve your problem

Hi My laptop speakers are suddenly got silent. First there was some crackling but after 2 or 3 day..speakers are completely out of order.

try cleaning your computer of dust using a fine air blower from a compressor making VERY sure that there is no MOISTURE in the air line specifically around the CPU central processing unit and your sound card dust causes static to build up in a computer causing it to overheat any many other problems
hope this helps

I'm using desktop computer, then my problem is my CPU has automatically shout down if i used in 2 minutes. please help me... thank you

As a saftey feature on newer pcs manufactures have equiped desktops and laptops with heat sensors. It sounds to me that the cpu is overheating. If this is a desktop, remove the side cover and clean all the fans, and check for dust build up on the cpu heat sink. If this is a laptop inspect the vents on the rear and bottom for dust or obstruction. Hope this helps ;)

Same thing, A900 overheating

The most common overheating problems that occur with laptops is usually due to a build up of dust in the ventilation grills. This is usually determined because the fan is running constantly.
All you have to do is make sure all the air vents, grills and CPU fan blades are completely free of dust.
Also make sure that the heatsink is sat level on the processor itself as an unbalanced heatsink will certainly cause the laptop to overheat.

Melting plastic smell/ computer slow and shuts down after about 15mins

Hi there.
The reason you can smell burning plastic and why its shutting down after a short time is because its overheating. This can be caused by a build up of dust on the CPU fan, overtime with dust build up computers struggle to keep themselves cool and tend to shut down unexpectedly, chances are this is the problem with your machine, my advice would be to remove the power cord, open the side panel of the computer and clean all the dust away from inside the tower, do this with a soft, clean paintbrush making sure you remove the dust carefully and gently, also make sure the CPU fan and the heat sync behind it is completely free of dust or any other foreign objects.
Once you are happy that its clear of dust, close or return the side panel, plug in the power cord and turn the PC on, you may find that the PC will stay on for longer with the smell dramatically reduced.

Please post back with the results and thanks for using FixYa!!

Clean the insides of your Desktop case.

1. make sure all the fans(CASE FANS, POWER SUPPLY FANS AND CPU FANS) are working dust and lint free.
2.remove dust and dirt build up in CPU heat sinks.
3. remove dust and dirt build up in the motherboard, RAM and
expansion slots.
4. remove dust and dirt build up on CD-ROM's, Hard Disk Drives and expansion bays.
5.apply new thermal paste on your CPU.

EMmachine Tower 600is power shut down after being on for 1 minute

The CPU is probably overheating because of dust build up between the fan and the heatsink

Just unplug the computer and open the case then very carefully unscrew the fan from the heatsink but do NOT remove the heatsink if you do not have to especially if it has an AMD cpu since AMD cpu’s burn up quickly if the heatsink is not perfectly installed or if the heat transfer grease comes off when removing heatsink so it is best to just leave the heatsink clamped down and just unscrew the fan

Once fan is removed you will notice a thick layer of dust build up that you could not see with the fan on and so just carefully remove the dust with an old tooth brush or something like that (it does not have to be spotless or perfect just as long as the main thick parts that were preventing the air from the fan from hitting the metal heatsink are gone then carefully put the fan back on the heatsink and now that the barrier of dust is removed the air will hit the metal like it is supposed to and no more overheat

You want to do this as soon as possible since it doesn’t take very many times with AMD CPU'S for them to overheat permanently and never work again (ive seen them burn up in just a few times).

p4 CPU same thing dust needs to be removed but be very careful when removing and replacing the fan and heatsink so that you do not accidentally break off one of the 4 plastic clips that hold it on because there will be no way to hold it on properly if even just one clip breaks and you will then need to go out and probably buy a different type of heatsink for it that screws on from the bottom of the motherboard and that can be quite a hassle to install since board would have to come completely out of the case to do so.

Once you are completely finished and power up the computer go into the system bios and check the hardware monitor to see the temp of your CPU if it says 70c or higher after just barley turning it on then maybe there is still dirt to clean off or the fan might not be spinning.
any temp lower than that is fine (temps vary from different motherboards if it is down in the 40's then your good to go with no worries but being in the 50's is ok too .. if its in the 80's then just pull the power cord because that’s way to high..
temps referred to here are all in Celsius by the way

My Fujitsu Siemens Pa 1510 laptop is constantly freezing randomly, with white/blue/black vertical lines.I have taken it to repairers who replaced inverter cables to no avail. How can I fix this problem...

My first thought would be to immediately check the processor fan for dust build up on the heats ink since a pretty common issue with allot of laptops is that a small layer of dust builds up on the heatsink sort of like a thin blanket that prevents the air from cooling the heatsink like it is supposed to and that of course causes the cpu to overheat at first and one of the first signs of overheating is the whole thing freezing up.. And at first it may just happen when doing something extensive that requires allot of cpu power but after a while as the dust layer gets a little thicker it will happen more frequently and could result in a dead cpu after a while. (I have seen this situation countless times)

only problem is that if there is not an access door (removable piece of plastic) on the bottom that allows direct access to cpu fan and heatsink then you will probably have to take apart the laptop somewhat to be able to see if that is the problem (if you do not feel comfortable taking apart the laptop then I would suggest mentioning it to them the next time you take it in) since there is really no way to shine a flash light into the vents and see the dust because the layer of dust builds up on the other side of the fan and is usually impossible to see through the vent.

NOTE: if you’re going to be attempting to do the repair yourself try to make note or which screws you remove from where since some of them are different lengths for a reason And be extra careful of ribbon wire connections when separating panels and so on

System shutdown

Systems that shut down after being powered on can point to an over heating of the CPU. Other factors come into play with overheating. Too much dust build-up on & under the CPU fan blades. Dust builds up in-between the heatsink fins (Thus the CPU fan can not cool the CPU chip.)
The CPU fan may be running too slow. When the PC system shuts down it’s saving you from hurting the system. You did not list the model number of you're system. Check you're system & clean the mentioned parts. Use canned air & a dry clean small paint brush to help remove possible dust buildup blow the dust away with the canned air.

Trouble shooting of motherboard

Hi thayal, systems shut down because of over heating. This is normal so nothing burns up. Try opening the case & clean the CPU fan. Remove any & all dust from the fan blades. Use a clean non used paint brush to help loosen any dust build up. Than blow the entire system out with canned air. Blow out the power supply as well. When finished put the case back together & see if the system shuts down.
