Pionex – award bios – amd 756 chipset “cmos ram failed”

Upgraded to Win XP and will get endless beebs during RESTART of system and sometimes during software instillation “will shut down on its own, but hang and beep”. If I do not completely cut the power for more than 15 seconds the system will continue to beeb. Ran a pc troubleshooting boot disk … “failed cmos ram” “clock ticking failed” and “alarm failed” Bad cmos battery ????? Or RAM ?????
