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
