Windows 7 major fps drops that dident occur previously

I originally had to send in my laptop to get the hard drive replaced as it was failing
when it came back i had to re-install windows.
after re-installing I restored from my back up,
the back up was the entire c drive
any way when i try to play any game i can hits as low as 2 fps
this does not happen if im using and external monitor

steps done to try to fix it
1 chance resolutions (one of microsoft suggestions )
2 re-install graphics driver
3 re-install sound driver(a suggestion that was on another forum)

don't post responses that are just saying you have the same problem, only potential fixes please. there are far 2 many forum posts where its just spamming the same problem with different computers
