Question Cant play games that are stored on HDD

May 31, 2020
To start off, I know very little about diagnosing computer issues, so bear with me LOL. So I have recently ran out of room on my SSD for any more games, so I uninstalled all games from SSD and just finished installing Modern Warfare to the hard drive and the game wont even open, also I had GTA installed on the hard drive before uninstalling everything, and I could not run that either.

My build specs are here:

I don't even know where to start to try and fix the issue, maybe I should just invest in another bigger SSD for storing games? Thanks in advance for any help, and for bearing with me as I know little to nothing about computers:ROFLMAO:
