To ensure if this is the case, you can try changing the power cables and power supply unit and then see if your computer still keeps restarting randomly. If yes, then you can try the next step.

Methods to Fix Computer Randomly Restarts to BIOS and Not Windows

The above steps will surely fix the issues with your computer if it is restarting randomly, but sometimes this can also happen that your computer boots into BIOS automatically instead of getting to the Windows load screen every time you turn it on. 

If you have tried rebooting your computer after exiting BIOS and it again goes to BIOS, this issue needs further troubleshooting. This issue has happened with most of the operating system versions such as Windows 7, 8, or 10. 

This can happen due to various reasons such as incorrect hardware connections, hardware damage, recently changed hardware, and so on. 

Tip- You can also try resetting the BIOS settings.

Here are some methods you can try if your computer keeps restarting to BIOS:

Method-1 Inspect Hardware Connections

If you have changed your hardware recently or have shifted your PC to a new position, the chances are the hardware of your PC is not inserted properly and that’s why your PC boots to BIOS when you load your Windows system. 

If that is the case,

  1. Remove all the peripherals such as external hard drivers, keyboards, and mouse and then reboot your computer to check if this helped.
  2. Shut down your computer and then remove all the cords. Press the power button for a minute and then plug in the cords, reboot your PC and see if it boots to BIOS or blue Windows screen.

Method-2 Select Right Boot Device

If your computer is still restarting to BIOS, it can happen due to incorrect boot order. You need to check if there is an appropriate boot device present in BIOS; if you find one, you can set it as the primary boot option. 

If you are not able to find your hard drive in BIOS; ensure that the disk is plugged in correctly and it is working on the other computer. If it is working fine on another computer, then the issue could be with your motherboard.

Method-3 Perform Windows Repair

You can also perform Windows Repair if your computer boots into BIOS automatically; 

You will need a bootable USB stick or CD/DVD disc; you can also create a bootable device from ISO file in Windows 10 and then boot your PC from this device.

  • Click on ‘Repair your computer’ to enter WinRE and then click on Troubleshoot > Advanced options > Startup Repair. Follow the instructions that you see on the screen to finish the Windows repair process.

Method-4 Check the CMOS Battery

The last tip is to take out the CMOS battery for a while and then put it back. After that, reboot your PC and see if it boots into Windows directly instead of BIOS. You can also remove the password for BIOS if you have set any and if that doesn’t help, change the battery.
