Spontaneous shutdown due to component failure occurs relatively rarely. This usually ends with the equipment completely failing to respond to any actions and not being unable to start it.
This component is responsible for all graphics on the computer, that is, displaying pictures, movies, games on the monitor. Very often, users are interested in the question: why the computer turns off during the game. The reason may be a power supply that cannot withstand the load and a graphics card that does not take graphics.
Components in the system unit may also overheat. If you hear a strange noise while working at your computer, it is better to think about buying a new hard drive. Bad sectors appear over time, and when the read head hits them, the computer may shut down spontaneously.
Sometimes it is difficult to clearly indicate the reason for the computer shutting down. However, a visit to a specialist involves a considerable expense and a long lead time. Before you get your device serviced, try these methods.
It is very likely that you will cope with the problem without an expensive visit to a specialist. When your machine is protected by a real-time program, you can be sure that no threat will be left out. When choosing an antivirus program, also make sure that it does not burden your device too much. A bad antivirus will slow down your computer and in extreme cases will turn it off. Take advantage of suggestions from industry leaders like Bitdefender Antivirus Using professional programs, not only will you not experience the extra load, and you will even notice an increase in performance thanks to the pc optimization feature.
Antivirus organizes the contents of your drive and Windows registry, manages the installed software, and changes many system settings to make your PC run faster and more efficiently. To cope with contaminants, reach for a container with compressed air. Unplug the computer, open the case, and take it to a well-ventilated area, such as a balcony. Then, remove the residual dust with compressed air.
Be careful not to bring the nozzle tip too close to the components — this can damage them! Keep at least a few centimeters of distance. For a laptop, compressed air is also useful for you. When the fan is running louder than usual, check the outflow and airflow and clean these ducts if necessary. Some laptop manufacturers, such as Lenovo, offer a very interesting option to clean the fan from dust.
When you launch a special application, the fan spins to high speed for about 3 minutes, so that a large part of the debris is blown out. Be waithed to suggestions to use a regular vacuum cleaner to clean your computer of dust.
Plastic brushes in vacuum cleaners instantly electrify and can cause damage from micro-surges. A weak or well-used fan usually does not do its job.
First, replace the fans in the housing. In some cases, when you remove or stop some components of your system, your computer crashes and shuts down itself. If this is the case for your computer, install the operating system again.
The problem should disappear. Don't try to run your system with the case off. It not only does not improve cooling, it actually hurts it because modern cases are designed to direct airflow where it is needed.
What Should I Do?. It's important that the computer have an unobstructed flow of cool air. Computer desks that hide the case inside a drawer or elsewhere need lots of ventilation to keep that all-important air flow. It's also a good idea to keep the case out of direct sunlight and away from other heat sources. Generally speaking, your computer is comfortable at the temperatures you are comfortable at. If necessary, you can install additional fans in your computer, or even a liquid cooling unit for the CPU, to bring down the temperature of the critical components.
And remember, you also can buy special sensors that can display your computer's internal temperature either on your screen on a chassis-mounted display. Some motherboard manufacturers, such as MSI, include a utility that displays the system and CPU temperatures without rebooting the system. Finally, if you are overclocking your system running the CPU at higher than its rated speed you are putting a serious additional heat load on your computer.
Try backing off to the system's rated speed. Remember, heat is the number one killer of computer components. With decades of experience, our Tech Pros are passionate about making technology work for you.
We love feedback! Make sure the PC is powered up properly by checking the electrical connections. Make sure you are using a working electrical outlet. You can test another electric device, such as a lamp, with the same outlet.
Bypass any power strips for troubleshooting purposes. Make sure the power connections to and from the PC are proper. Choose the type of PC you have below. Laptop PC A laptop PC has an external power supply and connects like below: One connector 1 plugs into the computer The other connector 2 plugs into an electrical outlet And sometimes, a third 3 connector plugs into the power supply itself Examine all cables and connectors for visible damage.
If they are damaged, they may need to be replaced. Make sure all connectors are firmly plugged in. The power cable looks like below. Examine the cable and connectors for visible damage. If you find any damage, the cable may need to be replaced. Make sure one end of the cable is firmly plugged into an electrical outlet.
Make sure the other end is firmly plugged into the power socket on the rear side of the PC case. Ensure this is set to the on position. If the I 1 is pressed in, it means the power supply is turned on. If the O 2 is pressed in, the power supply is turned off. All-In-One PC An All-In-One PC has an external power supply just like a laptop PC has: One connector 1 plugs into the computer The other connector 2 plugs into an electrical outlet And sometimes, a third 3 connector plugs into the power supply itself Examine all cables and connectors for visible damage.
To check whether your computer still has working fans, try the following: Look for any vents your computer may have: in the back, on the side or bottom. With the computer turned on, place your hand in front of the vents and feel if there is any air blowing. Depending on your results, you will have three options: There is no air blowing — This could mean the fans are not working and the computer has no cooling.
The air flow feels weak — The computer's fans may have dirt built up on and inside them which is causing them to slow down and not blow enough air to properly cool down the internal components. This can be fixed by cleaning up the outside and inside of the computer, and oiling up the fans. The air flow feels normal — This could mean the issue the computer is having is software related. There are a few different software fixes that may be attempted to resolve the issue.
For a desktop computer Turn the computer off and unplug its power cable. Open the computer case and remove the side panel. Blow compressed air to clean up the inside of the computer. Pay special attention to the fans. Also remove any wires or objects that may be touching the fan blades.
Blow some air through the vents as well, from the inside and the outside. Locate any fans and peel back their sticker partially to see the bearing. If there is a protective cap underneath, remove that as well. Add one or two drops at most of oil.
