A neighbor gave me his computer and when I went to try it out I discovered it didn't have any memory cards in it. So, I took a memory card from one of my computers and put it in it. I fired it up and then discovered the hard drive didn't have an OS on it. So, I decided not to mess with it and so I took out the memory card and put it back in my computer. Now my computer won't do anything. When I turn it on all I get is a series of beeps from the BIOS. No video so I can't see what the problem is. I know the monitor is good, I know the memory card is good and I know I put it back in correctly and I know the hard drive is good because I can test all these on another computer I have and they all work.

I seem to remember that the beeps are telling me something what might be the problem. So, my question is does anyone know what these beeps mean?

Here is what I get:

long Beep - short pause - two short beeps - long pause - two short beeps - short pause - one short beep
