Computer freezes when Geforce driver is installed.

[powerprogoose]

Hi guys,

I need help. I bought a 4k version of Lenovo y50 with the 512 SSD. It has a dual GTX 960m and an intel integrated video. It has Windows 8.1 preinstalled on it but I hated it and decided I would install Windows 7 on it. By doing that I ended up deleting the partition that has the recovery and stuff. I was able to install Windows 7 but I didn't realize how difficult it was to find drivers for this laptop. I had to install the driver for the integrated graphics before I could install the geforce driver. Once the geforce driver gets installed all hell breaks loose. If I right click on the desktop the busy icon/cursor appears and won't go away. If I try to do anything that has to do with the display at all then the computer freezes. I tried installing the driver with geforce experience but same thing happens and geforce experience freezes as well. My guess is that it may be confused whether to use the integrated card or the GTX card. I really don't know, I'm not a tech genius or anything and I know I should have just stuck with the Windows 8.1 but It's too late now and I can't go back since that partition that allows me to go back was deleted. Is there anyone out there that can help me? please...
