I prolly should have mentioned this earlier, but if you don't own the hardware you're mining on, you should not be doing it. You're literally asking for help setting up a system where you can mine for maybe a dozen hours a week, on hardware owned and maintained by your school? Ya, you're asking for all sorts of issues with that, both technical and legal.
No, no. That's not my intention. I'm no idiot. I just want to "borrow" the GPU while I am doing work and when I am not using it, I plug out the USB and the computer goes back to normal. Anyway, I only have access to it for about 3 hours per week, and most of the time, I'm doing school work that the teacher intends for us to do.
If that's illegal, then what about playing WoW and earning virtual currency on the school's computers? Or using the Internet (which the school paid money for) when you aren't supposed to?
Anyway, everyone has the right to answer or not. This is a question and I'm not threatening you with some computer virus if you don't answer. FYI, I know nothing of those. I'm only 16.
