Hi :emotion-1:

So you added new ram 2x1GB ram sticks from Corsair.

Is this the memory (  I got this from corsair.com )

Try and download Memtest and check your ram with this test or use Dell diagnostics.

Is the card okay with older ram ?

Try one stick at a time first though :).

I think I found the problem with the ram, I bought pc3200 instead of pc2700, would this make the difference? Was it the ram that stopped the graphics card from working or do I need more power?

The Radeon 9200 is a terrible card.  Geforce 5500 or 6200 or 8400 would be a better choice.

Rather than spend money on upgrading a 3000 though I would look at a newer machine like optiplex 620.
