Hi, i've recently reinstalled xp after having problems with my pc. Installation went fine until i rebooted and the graphics didn't look right so i tried to change the screen resolution but it wouldn't let me and now it's set to 4(bit) ...the sound isn't working either as it doesn't recognise my onboard sound card..i really don't know what to do anymore with it...can someone help me please. Also I don't have the original discs for the pc anymore besides my xp disc....if anyone has suggestions can you please reply. thanks
