HELP! Windows 7 freezes

[streetball]

Well...here is my results...
I've installed the driver as you said... no problems....I restarted the pc.... the intel graphic card had error... therefore the resolution was not proper... I uninstalled the intel and restarted again.... it installed it properly,but then the nvidia had error... I tried to install your driver once more but it stops the card cause it reports an error....

What do I do now?
