i have a pentium 3 733 mhz pc with winxp networked to a pentium4 2.6ghz pc by wireless linksys setup. i put a nvidia fx 5200 video card in the pentium 3 pc and now it won't connect to the host pentium 4. the motherboard in the pentium3 is an intel(easton)d815eea. shouldn't this board take the fx 5200? when i take it out it hooks right up. am i doing something wrong or is this card and mobo non-compatible.
