i'd suggest a clean install, and see what that does.
Don't know if it's something bad I've done in life, but it took me a THIRD clean ddu install of my graphics drivers (I unchecked all 3d stuff, and the Nvidia audio driver) and it's ok now it works as intended
One thing, I just hope that mouse issue goes away by itself.
Thanks for your help and rapid replies regardless. Much appreciated!
im gonna mark it solved for now might reopen it if it happens again.
Also, I tried booting into my main os on my other SSD (windows 10 1809 fast boot and hibernation fully disabled) and then back into my windows 7 install it's all good
Let's hope it sticks, thanks again
Edit : It also made os more responsive and fixed some pretty jammy issues with GeForce experience
