I recently put together a new computer, some new parts some old parts. The ram, gpu, cpu, and mb are new, hd and dvd drive are not. They were working before being moved to the current build. The computer was working fine after it was put together, then for some reason, it stopped booting up, and only gave me a black screen. There were no beep codes at first. I started taking it apart piece by piece to see if something wasn't working right and trying to boot it after each piece, then after I took the ram out I did the the 3 long beeps that shows there is a problem with the ram. I put the ram back in and it goes back to the original problem. Everything seems to be getting power, as all the fans are spinning, and the hdd seems to be spinning also. The gpu fan is erratically speeding up and slowing down though. There is no on board graphics on the mb. I've tried all the "fixes" that I have found on here already.
Thank You
