Auto shut down occurs due to overheating - Computers & Internet

CPU/ Processor resources and due to the heavy processing the PC heats up. Excessive heat up beyond usual is alarming and PC shuts down by itself when the processor/ CPU temperature exceeds the safe temperature limit. There are mainly two reasons for heat up.
Heating issue generally occurs due to fan failure, which may damage the system, if not checked properly. Another most likely cause of overheating is the dust present inside the PC, which clogs the fan and heat sink.
1. Make sure the fan is running. (if not, it needs replacement)
2. Clean the fan and heat sink (thermal module). Take out the fan and heat sink. clean them with the help of tooth brush and put it back.
3. Also, make sure that the PC is placed in a well ventilated environment and the air flow the the PC is correct.
The procedure is very simple and I believe immediate action is required to prevent any damage to your machine and data.

Hope it helps! Good Luck!

The BSOD (blue screen) is most often caused by a bad driver and sometimes by ram. Your computer can shut down suddenly if it's overheating but generally when it's from overheating it will start stuttering...running jerkily...before it shuts off. The screen will semi lock up, things run slow. Obviously it will also feel hot either to the touch or at least the air coming out will be hot or not moving at all. Heat is caused by a bad fan or fans including a bad cpu fan. Of course heat is a big problem.

Though you can adjust when the machine shuts down as a saftey precaution that you still need to address the overheating problem itself. A fan may need to be replaced or you may need additional air flow ie additional fans.

A major cause of heat is a dirty fan due to dust, pet hair etc. Computers, including laptops, need to be cleaned out periodically.

I would look into these issues before worrying about cmos adjustments unless you have changed the settings and this was the result.

If the Computer shuts down automatically, then the issue might usually be due to the overheating issues.
The overheating issues develop, if the Cooling Fan in the Computer is malfunctioning.
The Processors are designed to shut down automatically, if there are any overheating issues.
For such issues, it would be better to get the Unit examined at the Service Center.
Replacing the Cooling Fan should resolve the issue.

Hope this helps.

The Windows Defender Application is the Antivirus Software which will be pre-installed with the Windows Operating System(Windows Vista, Windows 7).
The Computer will always Shut down after any Windows Updates or any Operating System Updates are downloaded and installed.
If you are connected to the Internet and running Windows Defender, the Computer will automatically download the Updates for the Windows Defender Application.
Once the Updates are downloaded and installed, the Computer will prompt for a shut down.
The count down will be for 10 seconds.
After 10 seconds, the Computer will install the downloaded Updates and shut down.
This might be the reason for the Computer to shut down while using the Windows Defender.

If the Computer still shuts down randomly, the issue might be due to overheating.
All the Processors in Notebooks are designed to shut down automatically, if there is any overheating issues.
The overheating issue mainly occurs due to the malfunction of the Cooling fan.
If the Computer shuts down frequently, the issue might be due to the above factors.
It would be better to get the Unit examined at the Service Center.

If the Computer restarts randomly, then the issue might be due to any damaged Operating System Files.
But, if the Computer shuts down randomly, it is due to the Processor.
All the Processors will be designed in such a way that, if there is any overheating issues, the Computer will shut down randomly.
The overheating might occur due to the malfunction of the Cooling Fan in the Computer.
As this is a overheating issue, it would be better to get the Unit examined at the Service Center.
Replacing the Cooling Fan in the Computer should resolve the issue.

Standby light flashing indicates that a problem is occurring. The exact count of the flashes between pauses will tell a service shop what is happening. This could be the lamp shutting down due to overheating. Dust buildup inside the lamp-based projection TVs is an issue.
Overheating will destroy your $250+ lamp. I suggest you call an authorized service center and tell them the count of the standby light flashes (usually between 1 and 9 flashes)

Listen for fans coming on, as this sounds like overheating issue. If fans kick in and then stay constant or dont work at all.
The link is for Notebook hardware control, this will monitor the temp among other things (only reference as a guide any software can give you an indication but not exact temp) Generally if a laptop hits 90c it will auto cutout to stop major hardware failure normal running temp (40-55c upwards depending on use) http://www.pbus-167.com/
If the machine is overheating it could be due to blocked vents, faulty heatsink, fans not working or incorrect fitting and thermal paste.
In all honesty if this is due to overheat problems, as the machine has been cutting out my strong advice would be to do all the above ESPECIALLY re-apply thermal paste (arctic silver5) to cpu, it takes about 100-200 hours of use to start to work 100%.
hope this helps, let me know if i can be of further help

Does the lamp actually light up and project? If not, it's probably a dead bulb. Are there any flashing lights that might be displaying an error code? How dow you know it's not overheating? Remove the filter and give it a good cleaning. Some projectors measure airflow and, even though the heat hasn't built up, the projector shuts down because it predicts overheating will occur due to insufficient airflow.

Usually this problem occurs due to a thermal[overheating] problem. Make sure all vents are free when running the laptop. You can also fix this by upgrading the fan & buying a laptop cooling pad that sits underneath the computer when in use. Hope this helps & please remember to rate my answer. Thanks.
