Integrated Video Card

Ok a game called wurm online wont work (comp freezes after like 5 seconds on a cold boot)
and I have an intel integrated p.o.s graphics card.
Would i have to get a whole new computer to replace this thing???

No. If you have an AGP slot, you can use pretty much most of the video cards out there.

Even if you don’t have one, you can still use some of the lower end cards (though it would be better to replace your motherboard with one that has an AGP slot).
