What if my PC beeps when I turn it on after installing RAM?
Most PCs will beep once when starting up just to let you know that everything is OK. Beeping more than once, however, usually indicates a problem. Keep in mind that not all PCs use the same BIOS instructions.
The type of BIOS used in your machine will determine the sequence of the beeps (known as beep codes). Deciphering them will clue you in to what the trouble is. If you just installed RAM, and you hear more than one beep or one unusually long beep when you reboot, chances are the beeps are signaling a problem with your newly installed RAM. If that's the case, follow the steps in "What if my PC won't boot?"
