I found out the beeps are not from the motherboard- they were coming from the HDD and DVDR. My motherboard and case didn't come with a speaker, which is pretty annoying. The DVDR made the two short beeps, which the guy in tech support said it means connection problems or something not working and the long beep came from the hdd. I think the hdd might be defective, because the DVDR detects the os cd when I put it in, but I ordered a 99c internal speaker just so I can precisely diagnose it. It should be here in a few days and I'll let you know what the beep codes are. Thanks!
