So my other computer (PC-A in sig) was on, it was playing music and suddenly the monitor lost detection. Then I could hear looping music (that was playing) between a short interval (where the interval was under 1 second) from my speakers. Computer would not shut down so I had to force turn off. When I turned it on, the monitor could not detect the system and three beeps were sounded, all of the beeps were quick but the first one was slightly longer. I referred to my manual and it was a Base 64K memory failure (RAM?). I tried so far is swapping RAM which doesn't seem to work.
