Hi, Abit AT7 board beeps twice every 3 minutes when it is on. I am using windows xp but I am sure it's not a software problem. It beeps every 3 minutes even the computer is idle. I boot up with a linux boot disk to see if the problem is xp. but it still beeps twice every 3 minutes. CPU is about 55 degrees System is about 35 degrees. All voltages seem fine in the bios. Does anyone have any idea? My system is : Abit at7 amd athlon xp 2000+ 512mb ddr 333 3x maxtor hdd on raid ati radeon 9000 video card 40x lg cd burner floppy Thanks.
