A couple weeks ago I had updated my gt335m's drivers and all was swell. However, when I took the laptop out and switched it to discrete graphics, I found that I was unable to switch back to using the grapics card. I tried going through device manager to roll back the driver, however the card was nowhere to be seen and my computer seems to not be recognizing the card. Without the graphics card, the computer is pretty weak, and can't really run much stuff at all. Does anyone know how to fix this?
I just had the same problem today. I updated my driver and it made it so that i couldn't change it back to increased performance. I fixed it by reverting back to my previous driver by uninstalling the one that caused the problem. My M11x just reinstalled the old one and the problem was fixed.
