There are several causes for an unexpected shut down or black screen on your computer. With the right troubleshooting it can be easier to determine and fix the issue.
1. Overheating: Overheating of your computer can cause it to shut down unexpectedly. Overheating can be caused by high usage of the CPU, fan problems, too much dust buildup, or a faulty power supply. Your computer can also overheat if you have not updated your operating system or system drivers in a while. In this case, it is best to check your system temperature then to identify and solve the issue.
2. Power Problems: If your computer shuts down suddenly and without warning, it could be due to power related issues. Check if the laptop is getting sufficient power from the adapter, and make sure the connection is secure. Also, look for any loose wires connecting the power supply to the motherboard. If you have an older laptop, try using a different adapter to supply power to your laptop.
3. Software & Driver Problem: Driver issues are also one of the common causes of unexpected machine shutdowns. Outdated drivers or incorrect driver settings can easily cause this type of problem. Similarly, software issues like viruses or malware can corrupt the system and cause it to shut down or show a black screen. Regularly scanning your computer with updated antivirus software can help prevent such issues.
4. Faulty Hardware: A failing or faulty piece of hardware can cause a black screen or sudden shut down. This could mean a defective graphics card, a bad hard drive or a RAM issue. You can check each device separately to determine the source of the problem. If the problem persists, then it’s time to take your machine to a qualified technician.
5. Low Battery: Lastly, low battery can be a cause of a sudden shut down or black screen on your laptop. If the laptop has a removable battery, you can easily replace it with a fully charged one. Alternatively, you can plug-in the power adapter if the battery is built into the laptop.
No matter the cause, unexpected shut down or black screen issues need to be taken seriously as they can be signs of major hardware damage or system corruption. Try the above solutions first and if the problem isn’t solved, contact a repair professional as soon as possible.
