The first thing is to check the cables. If there are any loose cables then you fix them tightly. If you have connected the power cables to an extension with other equipment which uses high electricity such as Refrigerator, heater are connected then better change the extension.
- Check the Fan:-
Make sure that the Fan is working. You can hear the sound of the Fan spinning or not. Or else you open panel of the Desktop CPU or you open the bottom of your laptop to check whether the Fan is working or not. It should spin at the full speed.

When you open the Desktop CPU or Laptop bottom, remove the dust which has accumulated. Use a brush to clean the dust. If the dust accumulates on the fan then the Fan may not work properly.
- Update the Display Driver:
Always update the display adapter. You should have the updated and the correct driver for your display adapter. If in case you installed the incorrect driver then your laptop may restarts or show no display. In that case you can start your computer in Safe mode and then remove the incorrect driver. In fact you should always update all of your driver.
- Regularly Update Windows:-
Always update your windows regularly. Every month windows releases security updates. Update it regularly for better performance.

May be the last installed software conflicts with windows due to which your system shows error and restarts randomly. So you need to remove the last installed program. You should run the computer in Safe mode. Press “F8” or any other button according to the motherboard installed and remove the program.
- Check the hardware requirement:-
Whenever you are installing any program always check the hardware requirement. How much of RAM, CPU speed and hard disk space is needed? Check the requirement before installing or else your system may have to bear the heavy load.
- Reset the power plan options:-
May be you have messed up with your power plan so reset it.
Go to “control-panel” and then “power options.”
If you have selected “Balanced (recommended)” then on the right hand side there is “change plan settings”. Click on it.
Click on “Restore default settings for this plan”.
- Check the RAM for errors
Open the search box from the start button.
Type “memory” and you will find “Diagnose your computer’s memory”. Click on it.
Select “Restart now and check for problems (Recommended)”
Your computer will restarts and it will take 8-10 minutes to complete the process.
Now once the test is finished then you need to open the event viewer to see the result.
Go to “Control Panel” – “Administrative tools” – “Event Viewer”.
Click on “Windows Log” and then on “system”.
Look for “Memory Diagnostic” on the right and then open it to see the result.
My result shows that I have no problem with the memory. If there is a problem then you might considering changing the memory.
- Disable Restart on system failure:
If your software conflicts with windows then due to system error then your windows may restart unintentionally. So, you disable the system restart of system failure.
Go to “Control Panel” – ‘System” – “System protection” – “Advanced Tab”.
Click on “Settings” under “Startup and Recovery”.
Remove the tick mark from “Automatic restarts” under “System Failure”.
Now the computer won’t restarts if there is a system failure.
- Change the SMPS unit:
If nothing works then you might want to check the System Man power supply unit. Sometime your SMPS may not provide enough power for the motherboard. So, go to a service center and check and replace it if there is a problem.
