PC not accepting or recognising its IGPU

Specs: Windows 10
A few days ago, my PC started but was not posting. After a lot of hassle I managed to get it to start, however my second monitor was not being recognised. Usually, I run my main monitor from my GPU and my second from my IGPU, this may seem like an odd setup, and not really very practical, and I agree, however for reasons this is how I have set it up. (Please don't just tell me to plug my second monitor into my GPU because I cannot). Anyway, I have gone into the BIOS and checked multi monitors is enabled, I have tried changing the primary monitor to the IGPU and back to PCI-E, still no luck. If I disconnect the GPU it will start using the IGPU but after re-connecting it, it just ignores it again, and overrides the settings in the BIOS.

Anyone got any clue what is going on here?

I am not sure why you were able to do that in the past. Inserting a dedicated PCIe card usually disables the integrated GPU. There are some motherboards that do allow you to use SOME low level dedicated cards AND the integrated GPU at the same time. Maybe that is what you have. If so, check your motherboard manual for how to do that.

You may have or Windows may have updated your graphics driver and that may be interfering OR a Windows update itself is interfering with the set up you have.

You have to be a little bit crazy to keep you from going insane.

Do you normally shut down your PC every night? or was the restart due to something else? Explain what the "hassle" was you went through. The issue is probably either a BIOS setting or graphics driver/software setting. It's difficult to offer much help when no specs are provided.

Well, I tried simple things like removing the power cable, and then re-connecting it and booting which sort of worked, as my PC booted into recovery mode. Next. I tried taking out, and then putting in the CMOS battery, as this fixes a lot of problems.. Again, no luck. I can't remember exactly how I got it to boot correctly in the end.. I think I just messed around with removing the GPU until it finally booted.

You still haven't posted the system specs. We have no idea what you're working with.

"I tried taking out, and then putting in the CMOS battery"

That resets the BIOS settings to the defaults. Which means you should have immediately entered the BIOS & correct ALL the settings, not just the date/time. Every single setting should be reviewed, adjusted as needed, & then saved. Once again, without knowing the make/model of your computer or motherboard, it's impossible to offer much help.

Post your system specs!
