cooleddy4 - but the graphics card i want to replace is a SIS 651GX 3D, which i think is onboard?
BTW, what do you mean you think
it's an onboard card? It's not that hard to tell. Let me point out how to be sure:
1. Look at the connector your monitor cable plugs into on your PC.
2. If connector is part of the motherboard, then it's onboard.
3. If connector is not part of the motherboard and is instead on a seperate card, then your graphics card is NOT an onboard graphics card.
