Slow running games

Hi All

Just hoping someone can help me with an issue I am having. All of a sudden every single game I run (apart from online) is running so slow that it is impossible to play them. It first appeared whilst running Bigfish games. I have uninstalled and reinstalled
the game manager 3 times, uninstalled the game and reinstalled twice still so slow I can't play, some other games are also running very very slow.

Thanks in advance

Playing games is very slow

I have recently installed windows 10 and have tried to play some of my old favorite computer games,(Diciples, age of empires, stronghold) and they run so slow I can't even play them. Any suggestions?
