yeah ... you're kind of limited there with that motherboard. It's PCI or your on-board video. You might consider returning that pc. Do you know of the return policy of the pc or where you purchased it from? Another option would be to purchase a new motherboard that supports the actual processor you have in there. The processor is either P4 or Celeron ... not both.
um.... can you gimme a suggestion of a good motherboard that supports my computer... and can you also tell me what i need to transfer from my current motherboard aside from the cd roms and harddrive... and RAM
