Nvidia GPU problems

[pointlessjames]

So I started having issues with my Lenovo laptop just after Christmas and I wanted to try and clear them up. Firstly often when I boot up Windows and sometimes when I'm starting programs i get the message:

WerFault.exe - application
The instruction at 0x01cd00b2 referenced memory at 0x01cd00b2. The memory could not be written.
Click on Ok to terminate the program
Click on CANCEL to debug the program

Clicking cancel appears to do nothing.

I don't know if my next problem is linked but my laptop doesn't seem to be using my Nvidia 635M GPU anymore. When I try to open the Nvidia control panel I get the message:

Nvidia display settings are not available. You are currently not using a display attached to a Nvidia GPU

The Laptop then starts not responding and is accompanied by the first error I described.

Thanks in advance for the help!
