Today, upon waking up, I started my computer as usual. Unfortunately, it had a black screen with white letters, blah blah blah, a problem occurred and your computer shut down to save files. It gave me a few options like if the power went out, etc. click proceed as usual, or something like that. Anyway, once I got to my desktop, I hear this "BEEP" maybe more of a click. Anyway I figured that I was holding down to many keys at once, because that makes a specific sound. Nope. So I continue doing my routine, login to AIM, start Firefox, load iTunes. Then I hear it again. I don't notice it much until it happens the third time. Thats when I decide to count intervals between beeps. Roughly 35-36 seconds between beeps. Every. Time. O_o I figure, since my speakers are on, I'll turn them off. Nope. Nothing. Still the dreaded beep. I've found that its coming from my computer tower.. Sooooo, I'm asking the community for some help, anything I can do to stop this beep? Its a really aggressive sounding thing. Almost angry..
