Odd behavior... 1st, check for infection by malware... 2nd, check for PUPs.... 3rd, check for updates (BIOS, drivers, Windows)...4th, make backups (at least 2) of important data files (photos, music, videos, documents, etc).

Now, examine system closely - was it dropped? or hit by static discharge/brownout?

Now, saying no reason for issue, consider trying other software to see if same thing happens. If it does, download storage media test utility from maker and test storage for hardware issue.... test storage with CHKDSK ( https://www.howtogeek.com/howto/windows-vista/guide-to-using-check-disk-in-windows-vista/ ) for file system damage. If problem is only in one specific game, delete it and download and install fresh.

Let us know how it goes.
