emachine repair?

I agree with electro but it will run with just one ram card although very slow but will not harm the computer.
obviously if there is only one card then a replacement is neccessary.

If it's a repeating single beep, it normaly means that there is a problem with your RAM (it's your memory).
It can be a bad contact due to dust or corosion, or faulty RAM.

First, make sure that it's properly connected.

Turn the computer off and unplug it. Push down the power button for about a second.

Open the case.

Find the memory location. It's a rahter long strip holding some black chips mounted perpendicular to the motherboard in a long, often black, socket. It's hold by a pair of plastic clips, usualy white, one at each end.
If the sockets are coloured by two, you have dual channel RAM and you must populate the sockets with matching modules going into matching coloured sockets.

Push the 2 clips to make the memory module pop up.
Gently push the module back in until the 2 clips snap back into place. You must push verticaly, straight down.

Repeate this for every memory module if there is more than one.

Removing and reinserting your RAM modules dislodge dust and scrap away traces of corosion that could prevent proper functioning.

Close the cover and power up. If there are still beeps, it means that you have at least one faulty memory module.

Take one module and go to some computer shop. Ask for RAM and show them your module.

Great time to upgrade your RAM. Check how much RAM your computer can have and go for that amount.
