If the fan stops working the computer will **** down to protect the CPU from over heating. You might have something coming in contact with fan, if not you will probably need a new fan. Don't run computer without a working fan. mysleuth

It is possible to burn out a processor in a matter of seconds without cooling. Please do not attempt to restart the unit, until you replace the colling fan on the processor. If it's not the processor fan/heatsink, you may have lucked out, but don't restart it till you replace the fans.The fan that sits on your cpu is the main concern, if it's one of the others the board should shut down automatically in order to stop this scenario from occuring.

Keeps shutting down


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 power keeps shutting off


see the details and fix it. God bless you
All microwaves have some sort of a cooling fan to help keep the magnetron and controls at a tolerable level. Most OTR models will usually use the vent motor for the cooling fan also. Countertop units have a small fan behind the control panel somewhere. Either way, if the cooling fan is not working and heat builds up, it is going to open a thermostat. On some makes, this thermostat might re-set itself as soon as the temperature cools down. Other makes, you will have to replace the thermostat or fuse.
If this is your microwave oven repair problem, you will need to check the operation of the fan. Below in the component testing chart, you will see how to test the fan. Also, if possible, make sure the fan is not obstructed somehow and not turning. Also check your fan relay at your control board for voltage, if no voltage, replace control board. This fan should come on at the same time any cooking starts.

Fan continually runs at a high speed


There are a couple of things here. I am assuming you mean the cpu fan. Not sure if there is a vga fan. And the power supply, well, you have no choice here. Anyway, make sure the inside of the computer is lint free. If the heat sink is dirty (under the fan), then dissipating heat is a problem. Heat triggers the fan based on the tolerance temperatures set in the bios of the box...normally accessed via F2 or F12 on bootup. Yes you can increase those temps but this is risky...as overheating can cause instability and hardware failure.

Gateway 500XL .. sounds like the Power Supply was making a scratching grinding noise.. off/on... I first thought it was the CPU fan and changed it .. not solved... the PC just shut down... maybe...


Very easy to replace power supply as this is most likely the reason for the shut down due to heat. Make sure when ordering new power supply or buying from a computer parts store that you do not relay on them to give you the right one, you have to do your homework, after you get it do not unplug everything from the mother board, take your time and make sure that when you unplug you know where to plug back and wear anti static bracelet.

Acer Travel mate 7730 os xp laptop shuts down


make sure processor fan is working fine. you may hear the sound of fan on the left side of the laptop. and make sure its not getting heat soon. If the fan is not working you need to replace the fan. If if gets heat soon that means you have to put processor cooling paste.IF the fan is working fine and the processor heat is normal, then you need to re-fix the RAM. Then it will work fine..ok

After running for a long period of time, my computer starts making a clicking sound. Then it goes to "blue" screen. I was told to make sure my fan was running when the computer is started. I have noticed...


First thing replace your fan. if your computer shuts of, then the mother board has a fail safe when your cpu gets too hot. if that doesnt stop the clicking noise then its your hard drive, get a new one pretty soon or back up all your data.

Fans a very important in a pc, heat will destroy a computer this is why servers are placed in a controlled environment.

Computer does not fire up. I do have steady green light on power supply. All motherboard connections appear to be tight.I have come home before to a beeping noise in the past. After resetting the machine...


That beeping noise may be due to over heating.
Most machines today have a temperature setting that will turn the machine off once the temperature reaches a certain point.
Safety feature to avoid damaging your cpu and components.
The shut down and restarting allows the CPU to cool down briefly.
Thus allowing you to start the machine again. Usually it will shut down again once the temperature threshold is again reached.
Good test is let the machine sit for 30 min. If it immediately starts up and shuts down a few minutes later. Heat build is usually the problem.

Typically this is due to heat sink or Fan on the computer CPU.
Check to be sure both are connected to the CPU and functioning.
If you have a fan on top of the heat sink above the CPU. Make sure it is working correctly. Dust build up over time will eventually kill the fan bearings or reduce airflow. Heat sink can and will become clogged with dust also. Replacement fans are easy to find. Heat sinks are even easier to clean.
Depending on your machine and CPU position replacing the fan can be a challenge. But can be done in a few minutes with minimum tools.

Each bios has different post codes and it is difficult to tell what is happening with out knowing the bios of your particular machine. Listen for the beeps and check your computer manual.
You can also google for this. Here is a web site that lists a few bios P.O.S.T codes.
http://www.computerhope.com/beep.htm
Once you know the beep sequence you can look it up. Usually points to the problem and you can go from there.

Good luck!

Computer shuts down problem


When you take the cover off and start up, are all of the fans spinning? If the CPU fan doesn't spin, the system will shut down soon after starting to prevent over heating the CPU

New Computer Wont Boot!


when you say "the fan makes a noise like its getting ready to spin", which fan...power supply's or cpu? if you answer power supply, then the POWER OK signal is not returning to power supply and it then quickly shuts down to prevent further damage. double check a firm connection to mother board. If you answer CPU, then it becomes far more complicated. Try re-seating the memory chips.
