You have a Dell Optiplex 9020 SFF with an existing RAM setup. Initially, the 16 GB DDR3 worked well. After installing the CPU, a Core i7 4790 caused issues. Now you're seeing a black screen and loud fan noise. Inside, bent pins were discovered. You attempted to fix them but may have made things worse. Consider checking the motherboard connections, ensuring proper installation of the CPU, and verifying power supply stability. If problems persist, professional repair might be necessary.
