Acer Aspire 4752g Lags After Updating Nvidia Geforce driver

Hi peeps, I am a new guy here, hopeyou guys take care of me... Smiley Happy Btw, I have something bugging my mind... My laptop became laggy after updating Nvidia Geforce driver... My gpu is NGF610m 1gb intergrated graphic intel hd 3000... before the update my games run pretty smooth(320.79) but after the update it became more and more laggy... I am not sure whats wrong with my gpu?? i check the temp, it is pretty low (around 40+ during idle and 60+ to 70+ when gaming). I tried everything that suggested in many forums but it still got me no where... can someone here help me with this problem?? I could really use your help... Thanks in advance... cheers...

Roll back the driver installation and return to the previous driver.

Thanks... I will try by using the driver software acquired by acer... maybe it will runs more smoothly... btw, actually my device has been switched it's OS from Windows 7 Home Premium acquired by Acer to Windows 7 Ultimate where i got it from a computer store due to a problem happened (I guess it was a blue-screen of Death). Do you guys think by changing the OS causes my laptop running slow?? plus when I sleeps my laptop and once I turn it on, the sound is mute?? what is wrong?? is windows 7 ultimate causing this problem?? btw sorry for asking too many questions to you guys...
