My Windows 10 machine keeps restarting when I'm not around, what could be causing this? Just started happening recently, last week or so to my knowledge.

MBR keeps corrupting after restart

I have a machine that when restarted or allowed to go into hibernation, I receive a missing/corrupted master boot record message and Windows doesn't boot. I am able to successfully repair the MBR each time using Windows recovery console, but I'm unable to determine what keeps making it happen.

Dell Latitude E6420
Windows 7 64bit

Steps performed so far: -besides fixing the MBR after each restart or hibernation
-ran system file checker sfc /scannow
-ran chkdsk
-verified that ACHI was enabled in the bios

If I can't figure this out I will end up just reinstalling the operating system, but I worried that the issue with just reoccur later down the line. Any advice/recommendations would be much appreciated.

 

Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK

Windows 10 fails to update


When you finish testing the Avast suggestion, make sure that you restart your machine.

Then if the issue persists, please return to the trouble shooting list in post# 89

I think there are three steps that remain; the WU troubleshooter, reset WU components, and manual WU reset.
