Ok, I tried removing some RAM, cleaning it and placing it back, and now the pc tower light is green (no longer in orange hibernate color), the monitor is still no signal and the Mobo (I think) keeps beeping at me when I turn the pc on...

This computer is a Dell, and it only has 512 RAM...yet I have 2 256 sticks in there, but there are also 2 sticks of something in there from Dell (that are not labeled) that fill up the last 2 of my four memory slots. Anyone know what these are?

thanks Kathleen and n Purist
