Hello, I recently built a computer and when booting up, it doesn't give me a post beep or message. Fans are spinning etc. but no sign of successful boot. I took it apart until only the motherboard and CPU and I get 3 long beeps then reboot, and this happens over and over. When I put in the RAM, I have no beep but still no boot. Any ideas?
