Is your Windows laptop restarting repeatedly without any reason? If yes, then you are not alone. This problem is quite common, and I want to tell you that it is not difficult to fix it – you just need a little patience and follow the right steps.
Let’s see step-by-step how you can get your laptop back in control, in simple language.
Why Is Your Laptop Restarting Repeatedly?
First it is important to understand where the problem is coming from. Just like a car shuts down repeatedly, similarly a laptop can also restart due to different reasons.
- Hardware issues – This is the most common reason. It could be that the laptop is overheating (fan is blocked due to dust), or RAM is getting damaged. Sometimes the power cable is not connected properly and the system gets confused.
- Software problems – System files can get corrupted, drivers can be outdated, or a recent Windows update may have messed something up. Antivirus also sometimes overreacts and the system starts crashing.
- Power settings – Some features of Windows (like “Fast Startup”) seem helpful, but actually create problems.
What Should You Try First?
Turn Off Automatic Restart
Windows by default restarts the laptop immediately whenever it gets an error. This does not help in finding the real problem.
To disable it:
- Press Windows key + R and type sysdm.cpl
- Go to the “Advanced” tab
- Click on Settings in the “Startup and Recovery” section
- Remove the tick on “Automatically restart”
- Leave “Write an event to the system log” ticked
- Press OK and save
Now if any error occurs, it will not restart, but will show on the screen what the problem is.
Disable Fast Startup
This feature theoretically turns on the laptop quickly, but practically many times the system becomes unstable.
Steps to turn it off:
- Search for “Control Panel” in the Start menu
- Go to Hardware and Sound > Power Options
- Click on “Choose what the power buttons do”
- Click on “Change settings that are currently unavailable”
- Remove the checkbox of “Turn on fast startup”
- Save changes
This change alone solves the problem of many people.
How to Fix Hardware Problems?
Is Your Laptop Overheating?
If the laptop is getting hot, the system restarts to protect itself.
- Clean the dust – Dust gets stuck inside the fan and vents. Clean gently with compressed air.
- Check where the laptop is being used – Do not use the laptop on the bed or couch, the airflow gets blocked. Buy a cooling pad if you use it on a soft surface.
- Monitor the temperature – You can see how hot the CPU is getting with a free tool like HWMonitor. If it goes above 80°C, there is a problem.
Test the RAM
Faulty RAM is also a reason for random restarts.
Steps:
- Search for “Windows Memory Diagnostic” in the Start menu
- Select “Restart now and check for problems” (save your work!)
- Let the test be done (it may take 20-30 minutes)
- After restart, check the result in Event Viewer
If an error is found, then RAM will have to be replaced.
Software Fixes That Work
Update Drivers (Especially Graphics)
Old drivers create restart issues. To update:
- Right-click on Start and open Device Manager
- Expand “Display adapters”
- Right-click on your graphics card and open “Properties”
- Check the “Driver” tab and update if needed
- Keep checking Windows Update as well.
Run System File Checker
Corrupt files make the system unstable.
- Search for “Command Prompt”, right-click and choose “Run as administrator”
- Type sfc /scannow and press Enter
- Let the process complete (10-30 minutes)
- Restart
If this doesn’t work, try the DISM command:
- DISM /Online /Cleanup-Image /RestoreHealth
Do a Malware Scan
Sometimes a virus or malware is also the reason for a random restart. Do a full system scan using Windows Defender or whatever antivirus you are using.
If the Problem Persists…
Use System Restore
If the restart issue is recent, you can bring the laptop to its previous working state through System Restore.
- Settings > System > Recovery > Open System Restore
Check Power Settings
Go to Control Panel > Power Options and select “Balanced” power plan. Go to Advanced settings and set “Minimum processor state” to 5%.
Boot in Safe Mode
If the laptop is restarting in normal mode, but is running fine in Safe Mode — then the problem is with the software. Go to Safe Mode and uninstall recent apps or update drivers.
When Should You Seek Professional Help?
If you see these signs, consult an expert:
- The laptop remains warm even after being idle
- Noises are coming from the hard drive (clicking, grinding sounds)
- The power cord or battery seems to be damaged
- RAM tests are repeatedly failing
- Nothing in this guide is working
Expert tools or part replacement may be needed.
How to Prevent Auto-Restart Problem on Windows Laptop in the Future?
- ✅ Keep Windows and drivers updated
- ✅ Clean the dust of the laptop every 2-3 months
- ✅ Use a good antivirus
- ✅ If the laptop behaves unusually (heat, sound), do not ignore it
- ✅ Always keep a backup of important files ready
Final Thoughts
Random restarts are irritating, but in 90% of the cases you can fix it yourself. Start with simple fixes like automatic restart and turning off Fast Startup. If the problem is not solved there, then check the hardware – like overheating or RAM issues.
Pay attention, the laptop is protecting itself when it restarts. It is important to find the root cause. Follow each step with patience — most likely your laptop will start working perfectly again.
And yes, if you don’t understand something or it doesn’t get fixed, it is absolutely normal to seek help. Sometimes a fresh pair of expert eyes solves everything.
