GPU and intergrated graphics card wont work together

[OscardB]

Hi,
I've had my computer for quite som time and the problem between my GPU and intergrated Graphics card (IGC) has been going on all this time. I've tried everything I can find on the internet but the only thing that worked was deactivating the IGC through the device manager. Now, the problem is, as soon as I update windows or any display drivers, the damn computer activates the IGC and I get a black screen. The way to solve this has been to run the computer in safe mode, and deactivate it again. I wonder if there is a way to permanently deactivate the IGC, so it wont be detected anymore by my computer? Some of you may think it's a stupid idea since maybe I need it for future problems. The thing is, IT DOESN'T EVEN WORK. I have tried to disconnect my GPU and update the computer using only the IGC but all I get is a black screen saying "No signal".
I've even tried to remove the drivers but windows automatically downloads it upon restart.

GPU: Nvidia GeForce GTX 770
CPU: Intel Core i7-3770K CPU @ 3.50GHz / IGC: Intel(R) HD Graphics 4000

in BIOS, select the dedicated GPU as the primary.
Note, that monitor cable should be connected to the GPU, NOT to the iGPU MB outputs.

There is an option in BIOS called IGPU multi-monitor.
Set it to disabled and iGPU will be disabled, when discrete GPU is present in the system.

Depending on your motherboard the setting would look similar to this:
