ok, I've got a fairly new build that I have been extreemly happy with, but last night I went to sleep and got woken up by a long tone from my system speaker. It was about a 2-3 second tone followed by a pause and then repeat. Still groggy, I hit CtrAltDlt with no response; then I used the case restart button, which worked, but before it got to booting, I got the same tone pattern. This happens every time i start the computer. There is nothing OBVIOUSLY wrong inside and all I can gather is that somehow the motherboard took some kind of hit. Again, the beeping comes before ANYTHING else, no drive reads or anything. Any suggestions?
