A computer will alert you to trouble through beeps and other sounds.
If you have a problem with the operating system, the computer gives you different beeps when you start up the computer.
You hear the beeps in different scenarios, such as three long beeps or one long and one short beep.
These beeps can mean different things depending on what computer model you have.
A siren sound on a computer means the central processing unit is overheating.
This is true for any computer.
When the CPU gets hot, it makes a siren sound warning you that your computer is overheating.
At that point, the computer should be turned off to prevent damage.
Open the computer and clean it if you notice a lot of dust inside.
You can purchase canned air at most stores.
Follow the instructions on the can.
Check the instructions in the manual that came with your computer on how to clean the inside of it.
If there is a lot of dust, that alone can cause the heat sink to overheat.
Verify the CPU heat sink is properly installed and the power is connected.
Consult the manufacturer's instructions on how to open your computer and find the heat sink. It should give you instructions on how to check that it is properly installed and connected.
You should find it in the middle of the motherboard.
Make sure the fan is working.
Your CPU will overheat if the fan is not working properly.
Refer to the manufacturer's instructions for your computer for instructions to check the fan. Replace it if it is malfunctioning.
WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL.
make sure that your RAM modules and Cmos battery are securely seated
on some motherboards Cmos batteries are soldered in
Test all power and data leads that attach from motherboard to your hard drive IDE SATA

restart your computer the found new hardware wizard should activate
a computer needs power and data to travel through every working device and to its continue its cycle and to have and end to function
make sure all leads that are attached to your drives dvd\cd and floppy drive have secure make sure the connections and are not faulty or just replace them they could be faulty
a computer needs all electric current and computer data to travel to and through every working device and have an end to work properly so any faulty leads will end up with a computer error
also check the keyboard for secure dust free connection ps2 and or usb
Check you CPU central processing unit make sure its securely seated and has thermal paste it might be getting to hot the thermal paste will help disperse the heat
Thermal compound is a sticky paste that is placed directly onto the CPU.
Allowing for a more direct heat transfer between the CPU and HEAT SINK and preventing air gaps from forming between the CPU and heat sink.
Hope this helps.
