With the message you are getting on your screen,there are couple things you need to do.First thing you need to do is make sure your cooling fans are all working if they are your next step is to go out and get a can of compressed air to clean the heat sink on the processor and any other cooling fan that needs to be cleaned before doing this unplug your computer to be on the safe side.If the heat sink looks clean you may need to remount the heat sink using thermal paste.Remember after cleaning your computer try to clean it often this is one thing that most computer user's overlook.

Overheating cpu


Problem could be you need to repaste heat sink on processor.
Over time the thermal paste becomes brittle and no longer takes heat away.

Repaste processor and heat sink using thermal paste.
Also adjust fans to high speed always in bios.

Last shutdown due to thermal event


When the CPU overheats then it will shutdown (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 this 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 withdust the remove the dust and make sure the vents are clear and dust free. Use acan of compressed air to do this.

Automatic shutdown due to thermal event?is this the CPU fan?


Could be. It's just getting TOO hot in there. Listen and see if you can hear the fan working. Vacuuming out the CPU and all openings, case fan, power supply fan (vent) - as much as you can will ALWAYS improve heat related problems. Obviously, if you can not hear or see the fan working, you will know where the problem lies. If it the power supply fan, you will need a new power supply. Good luck. :)

The computer will just randomly do a windows shutdown and then restart. Cleaned, changed the power supply and still does it.


Computers may not be smarter than people, but if they’re designed properly, they will shut themselves down before overheating to the extent that they do themselves damage. If the smart person keeps turning the computer back on and figures out a way to foil the protection, the unit is probably doomed. Once a unit shuts down for thermal event protection, it may refuse to power back up for a fixed period of time, five or ten minutes, or it may begin to boot and shut down immediately as soon as it boots to the point that it can figure out that its too hot. The over-temperature protection is generally a BIOS rather than an operating system function, so one sign of an overheated unit is one that shuts itself down while you’re using it and then refuses to boot as far as the operating system unless you leave it alone for an hour or so to cool down. Unless you’ve been working in a very unfriendly environment, high temperatures, direct sunlight, etc, you should take even a single overheating shutdown as a warning to back up your data at the first opportunity and to give the cooling system a serious cleaning. Check the CPU fan if it is spinning and also the CPU itself put thermal paste. So that the heat from CPU will absorbed by the heat sink.

Auto shutdown


Usually this problem is caused by a thermal [overheating] condition. Best solution is to open the case and see if the cpu fan is working. If not replace with a new heatsink fan combo and make sure you use a quality thermal grease between the cpu & heatsink. Hope this helps & please rate this solution as fixya. Thanks.

Computer is switching of frequently


Try changing the cmos battery on the motherboard.
OR your PC could be overheating,check your bios to see if the thermal shutdown temperature is set too low.(assuming you can get into the bios)
Recommend new thermal paste on cpu,ensure fan/s are working.
