An alarm keeps going off?

I'm not sure of this, because really you need to give more information, what kind of alarm? But, are you sure the CPU fan is turning? It sounds to me like the cooling might not be working, causing the processor to overheat and trigger some kind of alarm?

Normally there is an indicator somewhere that tells you the fan RPM, maybe if you look in the bios?
