GeForce GT 740m problem

[Hossein salamat]

hello everyone. i have a Lenovo z510 laptop. i have big problem with its nvidia GT 740m graphic. some times when i open a game (no matter how Big or small) it lags or game crushes and i have to close and open the game several times until it gets right. but the intel graphic works fine with games all the time. i've updated the driver and set all of the settings on high performance. but the problem still remains.
sorry for my poor english. it's my 3rd language.

I would uninstall all graphics related drivers from Nvidia. Reboot the PC and then re-install the newest driver.
This will fix most driver/software related problems.

If this has been going on since you bought the laptop, you may want to look into returning, it could just be defective...

yes the problem was since the beginning but i didn't paid so much attention to it and now, 8 months later, it's kind of too late. i have to check to see if i have the warranty card or not. but i was hoping if anyone had the same problem and knows how to fix it. thanks for your answer.
