Sorry if this has been answered, but I couldn't find a solution in the forums/google.

Ok, I bought a new laptop and upgraded from win8 to win7. When it came to downloading the GPU drivers, before the program could even get started installing, it said "cannot install driver need intel(r) drivers first"

Fine, so I download intels integrated graphics drivers, and then successfully install the nvidia drivers for my 840m.

Problem is, under device manager, when my integrated intel graphics are enabled, my 840m drivers throws the most ambiguous error code known to man (code 43 "something's not working right". Thanks Windows) and automatically disables the hardware.

If I disable the integrated drivers and disable/enable the 840m drivers it says it's working fine, but I have my doubts that it's actually utilizing the 840m drivers.

I downloaded GPU-Z, and it can detect that I have an 840M, and it detects the drivers, but there doesn't seem to be a lot of 'clarity' on my screen, for a lack of a better word. I would think it would be a sharper image is what I mean, and i'm just not getting that.

Can anybody help?

here's my device manager

The laptop manufacturer has to provide the software to allow switchable graphics. If you moved to a OS that isn't intended for that laptop, you are out of luck. To get your graphics card back on, you will need to switch back to Windows 8.

Nvidia provides the basic drivers. The manufacturer has to provide the drivers that are able to switch them back and forth to allow optimus to work.
