Just an update for anyone interested...

 

My grandson freed up around 200 gigs of storage on C:.  I then used Partition Magic to shrink the C: partition and create a new one (Z:).  I moved Virtual Memory storage to Z: so that I had a separate partition dedicated to it.

 

The new issue is that a new Steam game - Five Nights at Freddy's: Security Breach - has been installed and regularly crashes.  My grandson uses this as the latest pathway to PC.  Google has been my friend - first suggestion is in Steam Properties for this game set a Launch option to -dx11.  This apparently causes the game to use DirectX11 and the game is now playable.  So we soldier on.  It is to be noted that the PC exceeds CPU minimum (Intel I5-6600K) with an Intel I5-10400F, meets system memory recommended (16GB) and exceeds the recommended graphic card specs (GTX-1060TI) with a RTX-3060).

 

Virtual memory will not cause any issues. 

DX12 has a variety of issues in games, so running a game in DX11 or lower is usually a good fix. 

I remember playing Starwars Battlefront 2 and it was a crashing and long loading mess, with how it ran on DX 12 by default but setting it to DX 11 and no longer had any issues.

I think your grandson will be able to "find" additional PC issues easily enough, might be worth while letting your daughter know there isn't a hardware issue. 

I am not a parent or know the family circumstances, so will not comment.
