A few months back, I bought a used t3500 motherboard , I decided to wait to test the board until I put the entire computer together, when I turned it on for the first time the screen was black, and the cpu was getting hot, there were no beep codes or post indicators. I tried removing the ram and turning the computer on and the same results. Switching cpus also did no help. The return warranty is gone and im now stuck with a non functioning computer. How can i fix this.
