If that was not helpful then maybe take out the CMOS for about 15 min let it sit. Then pop it back and try again, also make sure everything inside the computer is pushed in.
other then that I didn't find anything close to the beeping you have. sorry I cant be more help I will do a little more looking around, see if I can't find anything else.
