So this problem started yesterday out of nowhere. I went to play a game and noticed it was lagging really bad. I opened up CCleaner and saw that my machine is using my integrated graphics instead (Intel HD Graphics 4000). My dedicated GPU (Nvidia GeForce GT 640m) shows up in Device Manager and GPU-Z
. Every other issue similar to mine I've found online, their GPU doesn't show up in Device Manager or anything. So it seems like this is a software issue for me. I've tried reinstalling all of the drivers for my Nvidia card through GeForce Experience.
Both the integrated graphics and my Nvidia card show up in GPU-Z. Here's a screenshot: https://i.imgur.com/LaE6Csn.gif
Here's the steps I've taken to try and fix this:
- Reinstalled the drivers for my Nvidia card
- Tried disabling the integrated graphics in Device Manager
- Tried changing the 3D settings in the GeForce Control Panel to run everything using the Nvidia card
None of the above steps helped. My machine is just refusing to use my Nvidia card. Anyone have any ideas? Let me know if I need to post any other information.
TL;DR: I have an Nvidia GeForce GT 640M card installed in my laptop. My Windows is refusing to use it and instead uses the integrated graphics. Help?
