PC Overheating

Why does the PC keep shutting down whilst in operation?
If you PC keeps shutting down then it means that it is overheating and the shutting down is to prevent it from damaging itself. The optimal operating temperature of all electronics as somewhere around 21 degrees Celcius or 69.8 degrees Fahrenheit ambient air temperature.

4 Things you can do to prevent overheating.

Dust Removal - The first thing you can do to prevent overheating is to make sure your case fans as well as system fans are clear of dust as dust clogs up the flow of air therefore less cool air can reach the hot component. To do this you can use a vacuum cleaner. With a dust free PC you can expect around 10 degrees cooler in some cases, it all depends really on the operating conditions.

Invest in some case fans - Another way to prevent overheating is to invest in some good quality case fans, the sizes vary between 80mm to around 140mm, some can be even larger.

Replace thermal paste - You should always replace the thermal paste under the heatsink of your CPU every 4 to 5 years as over time it gets crusty and becomes less effective at dispersing heat. Thermal paste should be placed in a line about the size of a rice grain on top of the CPU in the centre.

Invest in a good CPU cooler - Most stock CPU coolers are able to keep temperatures at a reasonable level, but better CPU coolers can be purchased if you really want a cool CPU. These can range from Cooler Masters V-Series Air Coolers (V6, V8, V12) to liquid cooling systems by various manufactures such as DeepCool and Corsair. Remember - Most after market coolers are better than the stock cooler supplied with the CPU. For clarification it's best to have a one-on-one chat to a sales person at your local PC store.

There is a great FREE program on the Web called Hardware Monitor by CPUID. You can get it here.

Just click on the 1.17 Setup, english, as shown below circled in red, to download the program.

The Hardware monitor software monitors your systems temperatures in the background whilst you work. It shows current, minimum and maximum temps of your components such as:
- North Bridge and South Bridge motherboard temperatures.
- ACPI Power Supply temperature.
- CPU temperature.
- Graphics Card or Display Card temperature.
- Hard Drive temperature.

The diplay of these temperatures depends on the temperature nodes in your system. Newer Motherboards will have CPU, North and South Bridge temperature readings. The Hard drive readings depends on your hard driver, most SATA hard drives should have readings. Again the ACPI reading will depend on the quality of your Power Supply.

Harware Monitor also displays the fan speeds of your CPU as well as any fans directly connected to the motherboard.

With these temperatures on hand you can quickly isolate the overheating components and take action to ensure that they are kept cool.

windows keeps shutting down unexpectedly


Your computer is overheating, it is shutting itself down to prevent damage to the internal components.

Your computer should be serviced by a computer technician. He/she will clean the components and chassis of dust. This will increase airflow over the components, meaning your system will be stable and will not shut down unexpectedly.

Take care!

laptop just keeps shutting down and won't turn on


it may be one of the causes, but the main reason for it is the power supply keeps on fluctuating. You may call Acer for a possible replacement for it..

computer keeps shutting off every five minutes or so


Computer may be shutting od due to following reasons:

Computer Virus
There are higher chances of a computer shutting down due to the interference of a computer virus. The virus gets into the computer and fiddles with crucial sections of the operating system, which may cause the system to shut down automatically. You need to install a good antivirus software and get the computer scanned thoroughly for any malware and viruses. Also see to it that the operating system and all hardware drivers are updated.

Power Supply
The computer power supply unit is an equipment that is installed in the cabinet to provide power to the system for operation. Your computer can shut down, if there is not enough power supplied to it for handling the programs running. If you are using the computer for running intensive software such as PC games, the system would require more power than what is actually available. Another reason can be overheating of the power supply. After the power supply is used for a substantial period of time, there is a possibility of dust getting collected inside it. And this may cause it to overheat, resulting in the shutdown of the desktop computer. If the power supply is at fault, you may need to get a new one installed.

Overheating of the Motherboard and the Processor
As with the case of dust getting collected in the power supply, the computer motherboard and the processor can also collect dust, which may be the reason for their overheating. This may also be one of the reasons why your computer keeps shutting down and restarting. You need to open the computer cabinet and clean the dust off the computer parts. The CPU board and the processor can also overheat because of many applications running. If this is the case, then it is suggested to keep the running of applications as less as possible or increase the size of Random Access Memory (RAM). Bad capacitors on the motherboard is also one of the reasons, why your computer keeps shutting down very often.

The 'Automatically Restart' Setting
If you are using Windows XP operating system, there is a setting that indicates the computer to reboot if it detects an error in the system's operation. In order to check if this is the problem, click on 'Start' and 'Control Panel', then select 'Performance and Maintenance'. Click on 'System', then the 'Advanced' option, and select 'Settings' from the 'Startup and Recovery' section. You will find an 'Automatically restart' option, which you need to uncheck for preventing the system from rebooting. Read more on computer keeps restarting on its own.

These were the possible reasons, why your computer keeps shutting down and rebooting. You also need to check if the power cables are properly connected to the cabinet and to the UPS, as loose connections can also be a reason for system shutdown. The most common cause of the computer getting shut down or restarted is due to overheating of the power supply and other internal computer parts.

My laptop keeps shutting down at random times. I


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 notebook back on and figures out a way to foil the protection, the laptop is probably doomed. Once a laptop 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 laptop 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.
Good luck
