Lenovo laptop crashes after I moved steam games onto D: hard drive?

About a month ago I ran out of space on my regular C: hard drive, so I decided to move my steam games to the D: drive. Ever since then, it has been crashing at random points whenever I'm playing games. I get a blue screen informing me it needs to shut itself down and an error saying WATCHDOG_VIOLATION. I have done everything including, uninstalling and reinstalling Steam (several times) and trying to fix the drive using cmd. I own Windows 10, in case you are wondering.

Have you "repaired" the games from within Steam?
Right-click a game in the library, go to properties, local files and then "verify integrity of game files".

Steam will check for any missing or corrupt files and download replacements if needed.
