Details:

When first building the computer everything was going well, the out of case test was successful, it booted to bios and everything was detected, after test conclusion I put it in the case, attached a couple extra fans, after everything was set up the red CPU indicator light is now on (previously it was not, no OS has been assigned or used for the computer, brand new parts) I have tried reseating CPU, I analysed the pins, none of which are bent, there is an even spread of the correct amount of thermal paste on the CPU itself, none has touched any of the pins. I have removed three of the ram sticks and have kept one at the farthest edge away from the CPU itself, the PSU works fine, the fans are all working as they should, I don't know what to do.
