Dear LEWISB1903B,I understand that even after the procedures the problem still persists;
What exactly is the model and manufacturer of your graphics card?
Initially I recommend that you try the following:
Download and install Visual C ++:https://aka.ms/vs/16/release/vc_redist.x64.exe
Check for new updates on Windows Update:
1: Open the Windows 10 "Start" menu and select the "Settings" item.
2: then select the "Update and Security" option.
3: in the "Windows Update" section, click "Check for updates".
4: If there are no updates, the message "You are up to date" will be displayed.
5: if there is any pending system update, the message "Features update for Windows 10 ..." will be displayed, then click on the "Download and install" item to start the system update.
6: wait for the update download to finish and restart the PC, or schedule a restart to be able to finish the procedure.
If the problem still persists, try uninstalling the Steam app and installing it again;
I hope I helped, see you soon!
