Every once in a while when I reboot or cold boot , I get a double beep. It's one weird toned beep then the normal post beep. It happens very sporadically and I cannot figure out what it is. I check uGuru and everything checks out fine.

Also, yesterday I rebooted out of Ubuntu and I heard about 5-6 short beeps and the comp froze. I don't know if t was an Ubuntu error that caused it or something serious. Hasn't happened again.

Is there some sort of beep history log in the bios? If not, what is the best way to figure out the problem.
