Hi,
"beep" codes normally indicate a Hardware problem / failure.
Go to your Computer Manufacturer's website and look up your PC's specs to see what BIOS you have
Then read this about the "beep" error codes to try and see what has failed:

If you are unable to ascertain the Hardware problem yourself, contact the Manufacturer if under Warranty.
If not under Warranty, find a good, local Repair Shop to take it to.
Cheers.
