My computer seems to be working fine. I have noticed however, that when I eject a cd from my dvd drive, I get a faint beep coming from the motherboard speaker. I don't think it is the same beep that I get when I boot my computer. The boot beep is a quick somewhat high pitch single beep. The beep I get when I open the optical drive is somewhat lower pitched and possible a fraction of a second longer but I'm not certain. Any suggestions?

Sorry, left out some basic stuff. Running WXP-SP2. AMD 64X2 3800+. 600W PSU. Samsung Combo CD/DVD drive. 1GB RAM. This probably is going to make things less clear, but my computer just beeped at me for no apparent reason. I was not opening the drive or doing anything special, just surfing to the dal website from google.

What is the make and model of the motherboard?
