If, after entering the BIOS and changing any settings items, something in the system manager stops working or starts to function not as it should, then it is highly likely that you accidentally changed the wrong PC parameters. Often, computer problems that suddenly crawl out after working in the BIOS menu can be solved by simply resetting the settings. One of three methods will help you undo any unwanted changes and restore the BIOS to factory settings.
Instructions
Step 1
To implement the first option, you need to enter the BIOS. To do this, turn on the power of the PC and until the boot screen of your OC pops up, hold down one of the buttons or a combination of them on the keyboard. The required action depends on the BIOS version. More often you need to press F10, Delete or F2. Further in the BIOS, find the Load setup detaufs item, which will drop the settings to the initial ones. After that, you should exit the BIOS menu while saving the settings, which will help the Exit and save changes item or pressing F10.
Step 2
For the second method, you need to pull out the power cable from the PC, unscrew the bolts holding the side cover, and then remove and remove it. On the largest microcircuit, which is screwed to the case (motherboard), you can find a coin-cell battery. She is responsible for saving BIOS settings. It is she who will have to pull out for ten minutes, then return to its original place and turn on the computer. When removing the bios power, you can close the contacts on its site with a screwdriver for a couple of minutes before installing the battery back.
Step 3
The third method is also performed with the side cover of the system unit removed. It is suitable only for motherboards with the CLR_CMOS or CLEAR_CMOS jumper. To reset the parameters, you need to rearrange the jumper so that it captures the first two contacts, and wait a couple of minutes before returning it to its place. After that, the BIOS parameters will be set by default.
