Having problems with your PC Desktops ?

Computer when turned on will not boot and makes a long beep continuously and then makes like a siren sound

Answers :

The long beeps probably mean a problem with RAM. So try replacing it.\015\012Check whether the CPU Cooler (the fan on top of the processor) is working. If the fan is not working, the processor gets hot, and a siren sound is emitted. Also check whether power unit fan (at the back) is working.\015\012If RAMs are replaced and you still get the beeps, the problem may be with the VGA. (The beep sounds help to identify the problem, but the sounds differ with different BIOS models).
Power supply, system board, or keyboard problem more than likely psu problem
