Long continuous Beep when playing WoW Retail

[CatH56]

I just bought this computer this past Saturday.  I started loading up my games.  When I start playing one of my games (WoW Retail), after several minutes or more, my computer starts with one long loud continuous beep.  Nothing seems to crash, the game is still on and functioning and I am able to open my browser, no crash of the OS.  I have no clue what is going on.  I am not super techy, but if any of you can just guide me a little here to troubleshoot, it would be much appreciated.  I know some things about computers but I am not in the biz, just fyi

Thanks!

PS.  When I close out my wow game.  The beep goes away.  It doesn't seem to happen with WoW classic, or when I am just doing normal activities on my computer, such as browsing the internet or using word, excel, etc.

I updated the BIOS just now, went back in to play Wow retail, and for about 15 minutes all was good.  Then I exited retail, went into classic, and immediately the long beep started again.  I videotaped it.  Nothing crashed, and when I opened my Chrome browser (while still in the game) the beeping stopped.  I am just perplexed.

It seemed that my old speakers were the problem.  When I unplugged them from the computer the long beep from the computer stopped.  I went and bought new speakers and now I am having no issues.  Weird....
