Hello, I have an HP D530 SFF that shows model number: DC5000 when going in the BIOS/Boot menu/PXE boot, etc. Recent modifications: Reinstalling Windows XP Professional (No Service Packs; Even tried with SP3); Installing the BIOS Drivers; Re-flashing the ROM/BIOS Using ROMPaq. None of this fixed it. Is this a common problem? Any help is greatly appreciated.
