That beep sounds like the system can't find any usable memory. either the ram (memory) is bad or you can try and reseat it, it could have come lose.
Caution before touching anything inside the case ground yourself by touching the case to discharge static electricity that is harmfull to computer parts.
With the computer off and unpluged Open the case side, find the ram at the ends of each stick will be 2 white clips push down on these to releasr the ram. Then with the white clips in the open position line up the ram and push down untill the clips go back into the locked position. try and boot.
If no go then repeat the procedure only install the ram in the slot (same color) next to it.
If this all fails then I would try new ram
