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.

Check your Processor Fan. It might be too much dirty or loose.



Hope this helps.

SOURCE: Fan Malfunction??

Sounds like a heat issue, pop the side of your case open and turn on the PC, are there fans not moving? Take a close look at your processor fan if there is one.

SOURCE: Dell Dimension C521 power shuts off spontaneously

It sounds like your power supply fan may be overheating. The easiest way to determine this is to open the case and look at the fan while it is spinning- if it is indeed spinning at all. I find the best way to get an idea of the functionality of the fan is to shine a flashlight on it at an angle. If you can detect fluctuations in the rpm visually, you know where the problem is. Then it's a matter of changing out the power supply. If, however, the fan seems to keep the same rotation speed constantly, we'll need to look further. Let me know what you find out before we go deeper into the system.

SOURCE: Dell Dimension 9200 keeps shutting down and won't start up

the key issue on the uncommanded shutdown is the POWER LED. If upon shutdown, the power LED Flashes AMBER, then the power supply is suspect.

If no flashing amber indication, then the next think I check is the heatsink (Processor overheating) remove, clean and apply arctic Silver heat transfer paste, see if the issuje goes away

Last but not least if the system is failing to boot, and displays a 3 4 diag LED code, then you may have a RAM module that is bad or may just need reseating. Running diags off of the Rersoujrce CD is something to look at too

Thermal event won't ever allow computer to boot at all


"Computer unplugged from power, press the Power On button in, and hold it in. Hold it in for a count of 10 seconds. let go. Do this procedure two more times. (If the Power On LED lights up, do it again) What you are doing is clearing CMOS Error Codes. Check the Processor fan, check the Thermal Paste. Cheap as Thermal Paste is, and what it does for a job, best advice is to simply replace it. Need guidance post back in a Comment. Before beginning make sure the computer is unplugged from power, and you are FOLLOWING Anti-Static Precautions. Regards, joecoolvette"

Brian Packard;
"I cleared CMOS a few times (has jumper on board too) and even put new thermal grese on it....what finally did it was taking out the CMOS battery. As long as it's outl it works just fine, putting it back in causes an error again. Thank you all for your time however and I hope this post can help somebody else too."

My Maytag double stack gas dryer does not work, the screen is blank(not lighted)


Most clothes dryers have a thermal limiter or fuse, which is a heat-sensitive safety mechanism that shuts off heat to the drum or the power supply to the dryer if it overheats. Unfortunately, you can't replace a thermal limiter once it activates. The only choice you have is to replace it; your dryer won't operate properly until you do.
Although you can't reset a thermal limiter that has been blown, you can reset the dryer's two circuit breakers and restore heat to the drum and power to the dryer. However, after the breakers are reset, you'll still only have partial function of your dryer. For example, it might spin but not heat or it might initially turn on just to shut down after a few minutes. You must replace the defective thermal limiter to reinstate your dryer's full function.

Thermal Event


This is likely one of the following:

1) the thermal paste under the fan is dried up and needs to be redone
2) The case needs to be blown out of accumulated dust
3) the motherboard has an electrical problem (old capacitors failing etc.)

It could be all 3 issues.

If you are somewhat skilled the first 2 are easy.

The last one can be fixed in many cases
