i have good pc can i mine on it, if i don't have to pay for electricity? i have gtx 970 g1 gpu and intel i7 4790k cpu. i dont have to pay for my electricity costs. i used to play games but now i don't play them any-more. i was hopping someone will tell me if i can make a profit and how much i can make in a week by bitcion mining.
i dont have a clue how to mine if i will profit from mining can someone list in steps the things i need to start mining.

Main reason i got idea for mining is because i don't have to pay for electric costs. any advice will be helpfull
No, you can't. The days of GPU mining Bitcoins are long past.
