Windows 10: Windows Keeps Reverting Back After Restart

Since my daughter has installed Origin on my Windows 10 PC I have had nothing but problems. I can uninstall Origin without any errors but when I restart my PC it is back again as if the PC has reverted to the settings before I uninstalled it.I downloaded iobit uninstaller which removed the program fine but when I restart my PC Origin is back and iobit installer isn't installed anymore as if the PC has gone back to a previous date. Even the iobit installer file is no longer on the C drive where I saved it when I downloaded it!Also, shortly after she installed Origin there was a weird fault wher

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.
