i just upgraded my desktop to a DFI lanparty ultra B motherboard and an AMD XP 3200+. I stil have my pc2700 ram. On my desktop after i installed the motherboard i stil had my old xp 2000+ in it and it was working fine. after i installed the 3200+ and booted up it says "error loading operating system". I decided that maybe my motherboard was bad and had wanted to get a shuttle PC anyway so i decided to order one. i just got it all set up with the amd 3200+ and the pc2700 ram and get the same error "error loading operating system". this is with 2 seperate hard drives. Is it because the ram is only 333mhz? plz help!!!!!!!
