Changed Mobo, now GPU is giving me 15 FPS, used to get 80+ FPS

I recently did a PC transplant where the only thing added to the system was a new MOBO and some case fans. Everything is working except that when I go to start a game from steam (h1z1) my FPS is horrid. Used to be 80-120 depending on settings, now I am lucky to be pulling 14-20 FPS. I can't quite figure what is causing the issue. What I have done so far was update all my drivers and updated BIOS as well. Removed and re-seated the GPU and I am still getting issues. Here is a list of my Hardware:

CPU - I7 6700
GPU - EVGA GTX 760
MOBO - Gigabyte z270 k7
Ram - 24 GB of OEM (HP) DDR4 2133
PSU - EVGA SuperNOVA 750 B1, 80+ BRONZE 750W, Semi Modular

My next step will probably be a clean GPU driver wipe and reinstall

Any other ideas? Literally just changed the mobo, so I have a suspicion it is driver related.

  1. Is the monitor plugged in to the graphics card or the motherboard?

  2. Into the graphics card. I went ahead and went into the BIOS to see if there were any settings GPU side I could change, I didn't really find anything helpful but I did go ahead and disable the onboard graphics just in case

  5. What if ram frequency has changed in new bios settings or can your new mobo support 2133 mhz? As far as I know ram is most important factor in fps.

    I would uninstall all Nvidia drivers, then shut down and remove the videocard. Fire up the computer using integrated graphics. Make sure Windows is updated, the motherboard chipset drivers are installed or updated, the latest bios is installed. In short, get the computer in working order. Test it with a couple of programs if you need to. Then download the Nvidia drivers if you don't still have the ones you already used.

    Now reboot into the motherboard bios. It's a UEFI bios, so if you are in UEFI mode try switching to 'legacy' mode. Also, temporarily disable secure boot if it's enabled. Once you do that, save your changes and shut down. Then install the card and drivers.
