System boots in to XP just fine but occasionally getting a random beeping from PC speaker. I opened up the case and checked to make sure everything is seated properly but found no obvious problems. CPU fan was running fine. Also checked health status in the bios and didn't see anything out of the norm.

What does the ! mean?

Gigabyte GA-8IEXP rev 2.0
Award Bios 6.0

p.s. already checked pdf manual (crap!) and at bioscentral.com with no luck
