For anybody who's struggling with GPU mining, proceed to download basically any version of ccminer on github and then unzip it (for NVIDIA I'd recommend this one).
Once downloaded, if you're on Windows, press Windows + R and move around directories with the "cd" command (ex: 'cd Desktop' and then 'cd Mining Stuff') until you're in the folder "ccminer(...)" (that you got from extracting the .zip you downloaded at the beginning).
Note that you can press tab and it will autocomplete anything you start writing after cd
This is what it looks like in my case:
C:\Users\m3t30v10\Desktop\Mining\ccminer-x64-2.2.4-cuda9> (this is where you type)
And once it looks like this, type:
And you are good to go
Your first block mined should appear like that "accepted: 1/1 (100.00%), x.x kH/s yay!!!"
Happy mining!
Can I mine this ?
Thanks in advance.
