i have two pcs both using win xp and networked with a linksys wireless setup. never had any trouble. well i put a geforce 6600gt video card in my no. 1 pc, took the fx 5200 out of it and put it in the secondary pc. my mobo specs seemed to support the 5200. iits a pentium3 815 eea board. it has an agp slot that will handle up to 4x. well when i powered up both systems i couldn't get the second pc back on line. it wouldn't hook up. stupid me never even thought of the fx 5200 card, i tiried everything else until i finally, in desperation pulled out the 5200 and the pc hooked right up. my question after all of this is why does that happen. how does a graghics card keep a networked pc from connecting to the host pc.. i thought the card would work fine, but live and learn
