Please Try this :-
:- Perform each of the following tasks, in order, until the beeping stops.
Before starting each task, unplug the power cord and remove the side panel.
After completing a task, replace the side panel, connect the power cord, turn on the computer, and ()listen for a beep code.
NOTE:
If removing or disconnecting a hardware component prevents the beep code, that component is
probably causing the problem. However, a failed motherboard might produce beep codes associated with a component other than the motherboard.
Clean cooling components that have become clogged with dust. If beeping continues, continue to the next step.
Remove a memory module.
If the computer stops beeping, the memory module might be bad, is the wrong type of memory for the motherboard, or was not fully seated or connected. Reinsert the memory into the socket to see if a connection was the problem; otherwise replace the module.
Remove each memory module, replacing the one that was previously removed. If beeping continues after checking all the memory modules, continue to the next step.
If the computer has a graphics adapter, remove it.
If the beep code changes or continues with the same beep pattern after removing the graphics adapter, the adapter might still be good. Reseat the graphics adapter into its socket and continue to the next step.
If the beep code goes away, the graphics adapter might be bad. Try reseating the graphics adapter, making sure it is fully locked into the connector on the motherboard. If problems continue, replace the adapter.
Remove a PCI card.
If the beep code goes away, the card might be bad. Try reseating the card into its connector on the motherboard. If problems continue, replace the card.
Remove each PCI card, replacing the one that was previously removed. After checking all cards, if beeping continues, continue to the next step.
Disconnect hard drives and CD or DVD drive cables (IDE and ATA) from the motherboard socket.
If the beep code goes away, the cable or socket is probably bad. Look for bent pins inside the IDE socket on the motherboard and straighten any bent pins. Try reseating the cables into the connectors. If problems continue, the drive itself might be bad and might need replacing.
Disconnect each drive cable, replacing the one that was previously disconnected, until all have been checked. After checking all connections, if beeping continues, continue to the next step.
At this point, the problem is probably the motherboard or processor. Make sure any jumpers on the motherboard have not fallen off their pins and into the case.
