A single beep when your computer starts is not an error. It's to test PC speaker. If you don't hear a single beep, either your computer's power supply, motherboard, or PC speaker is bad.
It's unlikely that you have a bad keyboard, but a bad keyboard can cause a computer to emit beep codes, and changing out keyboard is cheap and easy.
Open your case of your computer and perform a close inspection of motherboard with a magnifying glass. It's unlikely but possible that something like a staple has been sucked into case and is causing a short.
A common cause of beep codes is a problem with RAM. Make sure memory modules are installed correctly by gently but firmly pushing down on each module. If that doesn't fix it, remove all but one memory module. Usually a single memory module must be installed in first bank. If that doesn't fix it, swap out that module with next one. You may need to identify type of memory your computer uses and try a brand new memory module.
The reason your computer is emitting beep codes may be because video circuitry is bad. If your motherboard has on-board video, try disabling it and installing a video adapter card. If your computer uses a video adapter card, try replacing it or removing it and enabling on-board video.
If that doesn't fix problem, try removing any expansion cards (except video adapter card) and disabling any I/O circuitry such as USB ports. If that doesn't work, try replacing power supply.
If your computer still has a blank screen and is emitting beep codes, only posibility left is a bad component on motherboard. It could be a CPU failure, but replacing CPU is usually expensive - if type your motherboard uses is still available.
Replacing a motherboard involves almost totally isassembling computer and may require reinstalling and/or reactivating operating system, and replacing some drivers. Hopefully, you will find information about meaning of beep codes, and they will indicate a problem easier to fix than replacing motherboard.
