No Signal To Monitor

I tired puttin on my pc the other day and information was not sent to my monitor. Also, I do not the the start up sound when my pc starts up nor the beep. Could this be a memory problem? My memory is only a year old.

Help needed asap because I have alot of work to do on it.

Thank

I do not the the start up sound when my pc starts up nor the beep.

I don't quite get you here. Do you mean you do not hear the beep or is there a special beeping sound?

there is no beep when the computer starts up. the monitor is also blank like if it isnt receivin any signal.
