Black screen problem

[porkster619]

I have a 64MB graphics card which is low but works for now.

The other day I plugged in a 128Mb graphics card into the appropriate slot but when I booted PC up it goes from a backlit black screen to a off black screen?

Im confused

We really need some more details about your computer and the cards and what/when exactly happened if we are going to help you.

Yeah, we'll need the model names of the cards, motherboard, and power supply.

64Mb: Nvidia Geforce MX440, Motherboard: P4M800P7MB-RS2H and the 3rd card was unknown to me, Just that it was 128Mb AGP

What about the Power supply?
Is it possible that the 128mb card just doesn't work?
