I have a Dell Dimension C521 that has an ATI x1330/1500 Graphic Card, and my card works horribly.
I found out that My Dell had an vnidia integrated card, and I want to switch to that.
I want to know how to switch that my integrated card with out physically removing my ATI card.
HERE is the information on removing a video card for your computer.
It may not be possible if you have the graphics card installed in your computer since it will override any setting in the BIOs and run from the card only and not your integrated graphics chip. Most likely you will have to remove the card. I don't know what you mean that the ATI card works horribly, but almost any dedicated video card is going to perform better than an integrated chip unless the card has just gone bad.
So then, is there a diagram that I can follow to remove the card?
I already looked through the Service Manual but there wasn't anything about graphic cards.
