I wish Nvidia would figure out why this is happening in the first place.
 
I've never heard of installing a video card causing issues like this.  Is it because with CSM on the bios is seeing the GPU as a bootable device then realizes its not so beeps 4 times then boots normally off of your HDD.
 
There are people online that just ignore it and say their PCs work fine other than the 4 beeps.  I also wonder how many people don't even hear the beeps because they don't hook up a case speaker to their MB.  I haven't used a case speaker in like 5 builds.  I mean with QLEDS and Post LEDs built into MBs whats the point.
 
 
When this first started happening some of the threads I read online people were telling people to switch PSUs and memory.  I mean what a headache for the end user.  I guess Nvidia didn't have one case of this in their testing.  Its happening with a bunch of different brand cards so this is definitely on Nvidia.
 
Well I hope you get your PC working again what a bummer to buy a shiny new toy and have to deal with this nonsense.

It was working. The beeps do not cause a performance issue. They are intentional a warning. The issue is in not disabling CSM. By now this should be disabled on every new motherboard by default and only enabled by the user who needs it for backwards compatibility. I've not used it in probably a decade.

I was able to reinstall windows 10 on csm mode like before. Everything works perfectly but the 4 beeps at the start are still there. Now I have my disks in GPT version so better than before. No way to install with uefi windows

Got the beeps too.
MSI Z170A GAMING PRO. It has a place in BIOS under boot for UEFI or UEFI and Legacy.
I chose UEFI and did a clean OS install but still get dem beeps.
I am going to go AMD next year so hopefully a new MB will not have this problem.

There's likely some CSM options that are turned on. They have to be disabled to not get the beep codes.
 
I've read that the beeps are just the card telling the motherboard that it's UEFI only, and if the motherboard has any CSM options on it will do that beep code.
 
You can (likely) also mute post code beeps to eliminate all beep codes.

It's strange because in my case, if I disable CSM, the video card is unusable, it displays a distorted screen when I load Windows. Very odd. I'll have to live with the beeps as the card works perfectly with CSM enabled. I am using HDMI 2.1 out to an LG C9 TV, maybe its related to that. 

Sounds like your windows install requires CSM. A likely fix, that isn't worth the time IMO, is to set pure UEFI and install windows fresh. Totally blow away the old install.
