Ok, I'm having a bit of a problem... I was running the sfc / scannow and it asked for my windows CD, which I have in hand, but when I insert it, it tells me its the wrong CD and asks for the Windows XP Professional Service Pack 3 cd...which I do not have...I only have the CD that came with the computer. So I figured I'd go to microsoft and download it....wrong, it tells me that i have to do it through my computer in automatic updates and tells me where to go to do that, problem is...under my control panel some icons are missing (looks like 3 are missing, just by the way the icons are situated)..."SYSTEM" being one of them! I'm searching now for another way to get in to do updates!!??!!
