I'm having a problem with my ubuntu 12.04 right after installation, I've restarted it several times and it went just fine. After that I'm getting these continuous beeps right after post that I haven't experience in my previous OS.
Sometimes it doesn't come, sometimes it does. When I boot or restart with a bootable flash drive connected, the beeping doesn't occur but when I start my laptop alone without any bootable flash connected, the beeping goes on.
How do I resolve this problem?
