I received the thermal shut down message on a computer that is rarely used. I have kept it very clean and only added 2 gigs of memory. The fan has always run since purchase, never shutting down if the system was powered on. I assumed I needed another fan, put one in the expansion slots and the same thing happened. Now I have three running fans, and a computer that stays on for 5-10 minutes. Will the hard drive be destroyed, and is this system salvageable?

"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,
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."
Three causes of ovheating: 1) Dust. Dust inside the computer, Dust around the vents, fans, cpu and heat sink. Take a can of compressed air and clean the dust out of the computer.
2) A Fan not working. Make sure the fan inside the Power Supply where you plug the power cord in works. Also there is a fan that sits on top of the CPU and Heat Sink. Make sure it works. Normally the system will give you an error message if the fan is not working.
3) Thermal Paste - The Thermal Paste around the cpu and heat sink has dried up or is too thin to keep the unit cool. Apply a fresh coat of Thermal Paste on the CPU and Heat Sink.
I would take the unit outside and give it a thorough cleaning, lots of dust accumulates on the cpu fan and heatsink ;)
Afterwards if its working stable I would update the bios firmware, just make sure it doesn't overheat during the upgrade, it's critical!
You might have a cooling problem due to a fan malfunction. It is not clear whether it's the power supply fan or the CPU fan; in the latter case you might also have a thermal coupling problem. The symptoms you describe certainly seem to point to such.
My advice would be to replace the fan (or the whole power supply; you might also want to purchase a "Silent Power" unit for quieter computing). If it's the CPU fan and you are comfortable with, or know anyone comfortable with a bit of PC servicing, you might want to also unmount the heat sink from the CPU and replace the thermal paste between CPU and heatsink. Clean the heat dissipator (the black metal grille over the heatsink) with hot water and a bit of soap and dry thoroughly, or wipe it energically with a dust brush, before mounting the new fan on it.
Thermal event are serious, (too hot) make certain of your fan/fans are working. Clean out the dust that has accumulated. Use you computer in a cool environment if possible. If the error continues, purchase some Arctic 5 ceramic paste take off your heat sync apply a very thin coat to the bottom of the heat sync (after you clean it of course) replace the heat sync. Also pull out the ram (memory) and reseat it. This should take care of it. If not please ask again. Please leave a rating...
if your computer is randomly keeps on shutting down this is a thermal issue which you need to address. check airvents, use compressed air to clean all possible obstructions between heatsink fan and processor. try avoiding blocking the airvent of your notebook. try also updating your bios
Firstly you need to get into the bios by pressing f2 or Del on start up and when in the bios look in the advanced menu for ACPI and meke sure that it is enabled, this allows the motherboard to recognise the auto shutdown through windows, then save settings and exit for a re boot.
Next click start>control panel>power options and check in the power schemes and other tabs, to make sure that the settings are correct for shutting the system down.
