Windows 10: How to switch GPU.

So I have two GPU, GPU 0 is intel and GPU 1 is geforce GTX. I mostly use geforce GTX, but for some reason. I think Windows automatically switched it to GPU 0, because my computer has been lagging lately. How do I fix/switch it? For context, in most game I get 60 fps, now I get 20 fps.

Airplane mode switch not working

Since the troubleshooting steps that were provided did not resolve the issue, we suggest switching on the Radio Management Service. To do that, please follow the steps below:

• Press Windows key + R.
• Type services.msc, then hit Enter.
• Search for Radio Management Service.
  
• Right-click, then choose Start.

Note: Never ever set this service to "Disabled".

Get back to us if the steps won't work.

 

Is there a way to force a program to use a secondary GPU?

I have 2 GPU's (Nvidia GTX 970 and 1080) and I want to force a program to use the 1080 for certain programs/games. Going to Settings>System>Display>Graphics Settings should give me the option to switch GPU's. Unfortunately it does not list both of my GPU's
nor does it allow me to change to another one, only the default GPU is chosen (the 970). This is a desktop computer and I have tried the Nvidia control panel and UEFI settings without much luck. If I tried selecting a program to run on my 1080 (through the
Nvidia control panel), it would still run it on the 970. I have tried switching the GPU's around with not much luck there either. If I can suggest to Microsoft the option in the Graphics Settings to list both GPU's for selection, that would be great. Otherwise
I don't know what to do. Does anyone have any suggestions? Thank you for your time.

 

B(lack)SOD after closing GPU demanding applications and games

I would like to suggest 2 more things if you don't mind,
1. Seat the GPU in another slot, if possible, and see if that helps anything
2. Use the GPU in another system, if possible, this is a step to determine that it is really the GPU and not multiple defective slots or something else from the system.
