Good morning and thank you for the reply.

If you have not done so already, could you try doing a clean-boot? This will prevent any programs from starting up when the starting when the computer first boots up. This can end up having adverse effects on the game when these programs are running in the background.
Open the task manager (CTRL+SHIFT+ESC) and select the 'Start up' Tab. Disable everything here and restart the PC.
