So my brother has been slowly upgrading his old HP desktop. Basically the only thing left of the original HP is the motherboard, ram, and the m.2. Recently the pc would not post and begin to give a series of beeps. Now normally I know pattern of beeps and can tell what it is, but this is apparently multiple issues and multiple beeps because there are a total of i think 12 beeps in different sequences and then it repeats. I have a short video to share to see if anyone can tell me what it is. Just for information he has installed a new hdd, an rtx 2060, and a new corsair 650 psu. The pc has also been transplanted to a new case with fans.
