Hi again, As it turns out, disabling the integrated card in the BIOS did the trick - you were right. I have restored the GRUB config file to how it was by default, and now everything is as speedy as I had hoped
I suppose this solution is simpler than adding the lines in the file anyway. Maybe I should've tried it first. Hope I didn't waste too much of your time Thank you again, you were a huge help!
