so when i press it on the screen stays black we move he mouse and it beeps over and over you leave the mouse and it stops bleeping but at the same time the screen stays black please help me??

Is this a new problem?

Any new hardware?

Does the monitor get power? Does the little light go to Green or is it Amber or is it Off. Do you get any screen such as "No Signal Input"?

What is the make and model of the computer?

Are you familiar with working inside it?

Yes the screen stays amber and it doesnt say anthing on the screen its a continus beep

the make and model im affraid i cant tell you i think its an old 1 its my friends hes had it for a while he hasnt used it in a really long time no new hardware

First thing to try is open it up and reseat the RAM.

If there is more than one stick then just try one and leave the other(s) out.

well the beeps dont come from the screen its from inside the pc so all i gotta try is remove my RAM and re seart then and try it again?

Yes. Continuous beep is most likely a RAM fault.

yes but only when i move the mouse when i stop the beeping stops

Well you have to start somewhere. If this computer has not be used in a long time check all the connections inside and out.

If there is a graphics card reseat that as well.

You can also reset the CMOS while you are in there.

Verify that all the fans are working etc.

There is a basic hardware failure somewhere.

If the monitor gets no power check those connections and perhaps try a different monitor. It should at least start up to tell you that it is getting No Signal.

Try a different mouse and keyboard. Make sure they are PS/2 and not USB.
