You will need
  • Computer;
  • - screwdriver.
If the computer turns on and "comes" to the status screen of the system, go to control panel, BIOS and locate the item called Restore default settings or some similar phrase. Select this item and press Enter. Then on the Exit tab, select "Save and exit" and confirm the changes made in the BIOS, also pressing the Enter key.
If the computer does not boot to the above point, reset the BIOS physically with the help of special switch jumper or button on the motherboard. In the instructions to the Board, locate the description page located on her jumpers and check which one performs the reset of BIOS settings.
Turn off the computer and remove the side case cover to access the Board. Locate the jumper and switch it to reset. On most motherboards this is a set of three pins, two of which are shorted together by the jumper. This jumper, move to a nearby location and wait a few seconds. Then return it to its original position and turn on the computer.
On some motherboard models, especially those that involve acceleration, a button for resetting the BIOS. If you have such a motherboard, just click once on this button, you can then turn on the computer.
Another way to reset BIOS is to remove battery from motherboard. Carefully remove it from the slot, wait a few minutes and reinstall. This method is good because the battery is clearly visible on the Board and its location is not necessary to find using the instructions, but it not works on all models of motherboards.
If the steps above did not lead to success, most likely, the data on the flash memory of the BIOS is corrupted. In order to "spice up" fee in this condition, contact the service center. For data recovery operations, you need a special device – the programmer, which is hardly home.
