Help if you can.   I think I installed the wrong bios because after flashing the bios I only get the posting on the screen of " Sytem Halted ! Alert ! Incompatible processor detected."  It will not reboot so I can get into the "Safe Mode".  I have the correct bios but I can't get the pc to open the CD to reinstall or a USB for an external install. What can I do to correct the problem? Nothing will work.....no keyboard, CD/DVD, USB's. How can I restore it to the originan setting? Is there a reset in the BIOS memory to restore the original BIOS? Has anyone with the same problem able to correct it & if so what did you do....? Please help.
