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.

How can I fix thermal shutdown of Acer b1-730?


Could be the CPU needs new thermal paste and reseating.this is usually a fail safe designed to protect the computer when the CPU is getting too hot.also check the cooling fan ......blocked vents as this may also cause overheating issues thus not cooling the internals which will activate thermal shutdown.

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.

When turn on my computer after a seconds the system is shutting down.. i don't know what to do, is there a problem with the processor?


A overheating CPU will shutdown and won't start up again until the CPU has cooled down.
The overheating problem (ie. thermal shutdown) is most likely caused by a faulty CPU fan or dust clogging the CPU fan and heatsink.
Check the BIOS CPU fan speed could be set too low, check the fan speed/temperature setting.
If this problem is not fixed, then the CPU will eventually fail.
Check the fan to see if it spins freely, if not then replace the faulty fan.
If the fan and heatsink are cligged with dust, loosen and remove the dust and use a can of compress air to blow away the dust.

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.

OVER HEATING


Hi,

Two possibilities:
  • the CPU is really overheating; and/or
  • the motherboard is falsely sensing high temp.
Corrective measure for an overheating CPU would be:
  • clean, re-lubricate or replace the fan;
  • clean or refit the heatsink. If it is overclocked, you may need a better heatsink.
If the CPU is not really heating up abd the motherboard is sensing erroneous temp readings, then the problem may be with:
  • BIOS version, try to flash and update the BIOS; and/or
  • check the temp probe underneath the CPU, it may need cleaning or slightly bending away from contact.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.
