I have toshiba sattelite, it was runnig fast when open games but now it runs slowly.

1 - What are the games recommended spec? 2 - What are your specs Or do u already meet them for sure?

First check updates for your windows and then for the drivers install them clear cookies and junk files. Open task manager after running the game and check is there any program running on higher processing that may be the last reason for your game to run slow. If still problem occurs you need to check is the copy of game faulty In general if the specifications are up to the mark the games will hang due to temporary, junk and cookies.

You could check with Can You RUN It if your hardware is compatible with the game you are trying to play. Although, if you say you could run the games before, it’s probably do to another problem. The most commmon reason for bad performance on laptop is overheating (besides bad specs). You could try to run some tests as described here and find out.
