Motherboard can not enter the BIOS how to solve

Motherboard can not enter the BIOS solution one:

1: You pull out the hard drive, two are unplugged, and then boot to see if you can go in,

2: Try another hard drive line. or switch to a SATA socket. If there is a condition. If it's closer to the repair point. Suggest going to the store to test. They have a motherboard test card. The problem with the motherboard can be detected. May be the motherboard hard disk chip burned. There may also be a problem with the SATA socket. Or try a different hard drive. Perhaps the hard drive power supply is not enough wire loss.

3: Motherboard self-test not carried out, the BIOS may be damaged or missing, it is recommended to physically restore the BIOS, on the motherboard to find the location of the button battery in the vicinity of a clear bios to find a three-pin, the shutdown of the case of the original buckle two stitch jumper received another mouthful on the line, the middle of the stitch always to use , the difference is only two of the outer ends.

Secondly:

1. The boot needs to press the F1 key to enter, mainly because the BIOS settings and the actual hardware data does not match the cause,

The CMOS battery can be cleaned and then powered on

2.warning! CPU has been changed! Please Enter the CPU speed CMOS setup and Remember to save before exit! This indicates that the BIOS settings are missing, to reset the BIOS to boot and hold the "Del" key to enter the settings, see your motherboard instructions.

3.CPU has been changed please re-enter CPU settings in the CMOS setup and remember to save before

Some motherboards have a FSB jumper, the default is 100MHZ, and some motherboards do not support automatic FM. You just go into the BIOS and set the FSB to your CPU standard FSB.

The motherboard does not enter the BIOS solution two:

1, the boot time memory detection for a long time

Symptom: After changing the motherboard once, each boot memory must be detected very time to enter the operating system.

Fault analysis and Processing: memory detection is a necessary process for computer to start. It is estimated that the "Quick PowerOn self Test" item is not set to "Enable" in the BIOS so that the memory is checked 3 times. Set it to "Disable" and then save the exit so that it can be quickly tested for memory when it starts.

2, the BIOS can not be set

Failure phenomenon: After the computer boot into the BIOS setup program, in addition to setting the "User password", "Save Modify Exit" and "Do not save Exit" 3 items, the rest are inaccessible.

Failure Analysis and processing: This phenomenon is estimated to be damaged CMOS, you can try to discharge treatment, if the CMOS discharge after the failure can not be resolved, you can also try to upgrade the BIOS. If the failure persists, it may be a problem with the CMOS memory and replace it.

3, the computer is not normal after the BIOS is refreshed

Symptom: A computer can start after the BIOS is refreshed, but sometimes it freezes when it is not finished, or crashes when it enters the operating system.

Failure Analysis and processing: The cause of the problem should be caused by refreshing the BIOS, it is estimated that the BIOS program or BIOS version of the other motherboard is not correct. Because motherboard manufacturers often launch a chipset of the motherboard, will be introduced after the upgrade and improved version, so you can add some new features. For this upgrade and improved version, there is no significant change in functionality, so the hardware design changes are very small, the BIOS program is very similar. So, even if the BIOS is wrong, sometimes it can be started. Since the computer can also be started, you can try to enter the DOS real mode to brush the original BIOS program back, you should be able to solve the problem.

4, how to enter the notebook computer BIOS

Failure phenomenon: A second-hand Compaq notebook computer, need to enter the BIOS to make some settings, but do not know the shortcut keys.

Failure analysis and Processing: Most laptops enter the BIOS in different ways than desktops, and most laptops are in [F1], [F2], [F10] or [Ctrl+alt+esc] keys. Many other laptops can also set up the motherboard BIOS through a dedicated program.

5, after the elimination of CMOS can not start

Failure phenomenon: In the BIOS modified the hard drive parameter settings, after saving reboot, in the system self-test, the speaker alarm sound, start failure. Turn off the computer, the motherboard above the jumper to clear the CMOS, and then set the jumper to the default state after the power-on, power LED is not lit, the CPU fan does not turn, the computer can not start.

Fault analysis and processing: it is estimated that after switching off the computer and socket, the computer power plug due to the quality of the socket problem, still under the charged state, resulting in the elimination of the CMOS is not successful. Unplug the computer power socket, plug in again, then turn on the computer power switch, you can clear the fault.
