How did you flash the bios? In windows or dos? If you have not flashed in DOS, why not? If you still insist on flashing in Windows do this: start winphlash and press advanced button. At flags check only verify block after programming. Anything else should be unticked. At DMI choose update the bios and not the DMI.
i flashed it in DOS using a bootusb it said successful and hit anykey to restart so i did and its now corrupt D;
