I built a rig back in August and am an experienced builder, (For other people), who has used this forum many times. Since building my rig, I have been having a multitude of problems, which after 200+ hours of my won troubleshooting, have gone unsolved. I am a 15 year old boy who owns his own business in the PC market and I am quite concerned with my failure to deduce these issues. After much internal debate, I have resolved to sell the PC in the next week if possible. It's heartbreaking to see the PC go but Its more painful on my desk, as a reminder that I have failed. Then I thought back to all the times this forum has helped me and have decided to give it 2 weeks. Any and all help is greatly appreciated :) My Issues, Components, and Attempted Troubleshooting are the following:

Components:
