Re: pc sht down stating thermal error. suppose processr...
Most of the time you'll never hear the CPU fan. If you don't hear the normal fan sounds coming from your computer, it is most likely the power supply cooling fan. Hold you hand at the back of the computer where the power chord plugs in, while the computer is running, and test if you feel air blowing on your hand. If you don't, then replace your power supply. Make sure, when checking for a new PS that you get the correct pin count. Best to order from Dell since proprietary systems usually use proprietary parts and a generic PS won't fit in the opening at the back of the computer (alignment of the plug and the fan with the opening, etc.)

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.
"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.
When the CPU overheats then it will shut down (i.e. thermaloverload) and won't boot up again until it has cooled down. If this is theproblem is not fixed then the CPU will eventually fail. A faulty fan causes the problem or the fan and heat sink assembly are cloggedwith 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 surethe vents are clear and dust free. Use a can of compressed air to do this.
A computer that shuts off unexpectedly is most of the time caused by heat. Check if the fan in the power supply is working fine by checking the back of the computer. You can take out the CPU too, clean it properly before adding a new layer of thermal paste. In this way, the heating issue will be eliminated.
Yes, it probably is the processor over heating, the bios then shuts the system down to save the processor from damage. The only way to cure this is by taking the heat sink and fan off the processor, wiping all the old coolent solution of the processor and fan then reapply new coolent, this should solve the shuting down issue.
This is typical of a overheating (thermal shut down) CPU problem. When the CPU overheats and shuts down, it won't bootup again until the CPU cools down. If this is not fixed then the CPU will fail. This problem is caused by either a faulty fan or the fan and heat assembly is clogged with dust. Check the fan to see if it spins freely, replace if faulty and clean the dust off the fan and heatsink assembly. Also apply fresh thermal paste to the heatsink/CPU.
