Why Does My Laptop Keep Restarting By Itself?
The main reason your laptop keeps restarting is because of corrupted drives, malware infection, dirty fans or a faulty motherboard.
- Not enough RAM
- Faulty power supply
- Overheated processor
- Corrupted hardware
- Malware infection
- Dust and dirt
Not Enough RAM
All apps that run on your laptop require some memory. If you encounter the problem of constant rebooting, you should check your RAM and get a new one if needed.
Faulty Power Supply
If your laptop is always dependent on an external power source, you should check whether the power supply unit is a cause of the constant reboots.
Multiple applications and heavy programs cause your motherboard to heat up. The overheated processor causes big problems for users. Check your computer’s fans to see if they are working fine.
Corrupted hardware drivers are a big nuisance. It is better to get your hardware component checked for any malware that can be detrimental to its performance.
Viruses can easily seep into your system. Malware infection usually stops the laptop from working smoothly. Constant restarts are a sign that something is not right with your PC. Run a thorough virus scan and check for any corrupted files or malware.
Dust And Dirt
Dust in the CPU often causes your laptop to force restart. To resolve the issue, get your internal hardware cleaned and free from any debris buildup.
