Computer keeps re-booting

Hi,

Thank you for your interest in Windows 10.

I suggest you to follow the methods below and check if it helps.

Method 1

Disconnect all the external devices (printers, scanner, USB (universal serial bus) drives, etc...) Except mouse and the keyboard and then check.

Method 2

I suggest you to run in-built Power troubleshooter and check. Follow the steps:

• Press Windows Key + X.
• Click on Control Panel.
• Select Troubleshooting on the left pane, click on
  View All.
• Click on Power to run the troubleshooter.

Method 3

If the above method doesn’t help, I suggest you to reset and restore all of the default Power Plans back to their default settings. Follow the steps:

• Press Windows Key + X.
• Select Command Prompt (Admin).
• At the command prompt, type powercfg -restoredefaultschemes, and then press
  ENTER.
• At the command prompt, type exit to exit the Command Prompt window.
• Restart the computer and check with the issue.

Method 4: Clean boot

Putting your system in Clean Boot state helps in identifying if any third party applications or startup items are causing the issue. You need to follow the steps from the article mentioned below to perform a Clean Boot:

laptop doesnt boot automatically

This is what happened.

1. Did a repair install and later disabled hibertnate in CMD.
2. Enabled legacy option ROM in BIOS.
3. After a few times startup ( i used the system in such mode for 5 days), changed boot option back to default.
4. Vola!! It boots automatically to win10 without any keypress. Tested it with many starts to confirm the same.
5. Re-enabled hibernate option using CMD and later selected Fast Startup.
6. System booted normally, without the need for any keypress.

I do not know exactly whether such steps resolved the problem or what else happened, hence cannot suggest above steps.

Many thanks to all members who helped to troubleshoot problems.
