Was it my graphics card or my motherboard?

Well, I have a crap compaq presario and for some reason, I wasn't able to connect my graphics card because I would get no signal. So I bought a new motherboard and cpu. I'm expecting my package to come this week, but do you think it could've been my graphics card?

Whenever I put my graphics card into the slot of the Compaq PC, the graphics card fan would would turn on, but nothing else would. Only way my PC worked was with using the onboard videocard. The card is pretty new, and it's NOT a powersupply problem. Could it be because the fact that the Motherboard was REALLY old(bought around 2003-4), or because the graphics card doesn't work? (The video card was a GeForce 7600gt)

I am leaning towards a motherboard issue. The 7600GT uses the PCI express graphics port. These were introduced in 2004, so an earlier model Compaq may not have had this.

Newegg recomends a minimum of a 350 Watt powersupply, or it needs a 400 Watt to operate in SLI mode.
