I have an HP Compaq dc5000 sff. I clean fresh installed windows 7 professional. Whenever I reboot or shut down and turn back on; just before the os boots, it stops and prompts, "FATAL ERROR: Failed To Locate Necessary Table(s) To Make Adjustments. Press Any Key To Continue Booting". After I press a key, it continues a normal boot and I can go on using the computer as normal. Various forums explained to try: 1) windows 7 installation disc's start-up repair option "Tried it, didn't find any problem." 2) cmd prompt - sfc/scannow "Tried it, didn't find any problem." 3) reinstalling windows 7 "Tried it, still have the problem." 4) replacing the cmos battery and resetting cmos "Tried it, still have the problem." I'm currently out of options. This is really bugging me. Can anyone help?
