Low FPS/Stuttering on a cold boot - After a Reboot all works fine?

Hello,

- My first ever post on a forum, so I apologise if I've posted in completely the wrong place.

I'm currently experiencing a really strange issue with my FPS on all games after a cold boot. After a reboot this issue goes away and my FPS goes back to how it should be until I perform a cold boot again...

So for example on Killing Floor 2...On a cold boot I get around 80 FPS with Stuttering, but immediately after restarting my PC (warm boot) I'll get 100+ FPS without stuttering at all - Which is obviously what my card should be performing at.

I have tried all sorts so far:-

- Various Benchmarks (CPU, RAM & GPU) - RAM and CPU benchmarks don't change at all regardless of a cold/warm boot whereas the GPU's load on a cold boot is around 35% and on a warm boot it goes up to 80+% - Not too sure why this happens/
- Messed around with various settings in the BIOS - Use a Gigabyte motherboard. Changed PCI-E Gen 1 - Gen 2 - Gen 3 and none of them make any difference at all.
- Re-mounted my GPU in another PCI slot.
- Re-flashed/updated BIOS
- Re-installed graphics drivers.
- Re-installed chipset and other motherboard drivers.
- Tried re-formatting/re-installing OS
- Tried a different PSU slot which resolved the issue strangely for two cold boots but then reverted back to the same issue.

My Spec:

CPU - Intel Core i7-6700 3.4GHz Quad Core
RAM - HyperX Savage 16GB (2x 8GB) 2400MHz DDR4 RAM
MoBo - Gigabyte B150M-D3H Intel Socket 1151
GPU - Gigabyte NVIDIA GeForce GTX 980 Ti 6GB Card
OS - Windows 10 Pro 64-Bit

Please can anyone help me?? - This is driving me crazy!

Thanks!
