Game in earphone. Problem sorted.
I do use earphones but my wife can’t hear the TV, lol.
I have been looking at the gear I bought to build the pc and it was built 5 years ago (wow, how time fly’s) and the gfx card was recycled from my last machine so that is probably 6 years old. I will do everything suggested above but I think a new gfx card is called for and I am going to look into water cooling both the GPU and CPU.
