The computer will make a very loud sound when you turn it on, and then you have to press F1, what is

1 。The power supply of the graphics card is not in good contact, remove it and replug it, and connect it if there is a power supply.

2。After entering the BIOS, select the first item enter, enter another page, and then select one of the items with it, press Enter, select the item of no or something, and then F10, and then the Y key!

3。Go to the BIOS and ban the floppy drive. Drive A in the Standard CMOS Features project in the BIOS is set to None.

4。It's time to change the motherboard battery.

6。Once you're in the BIOS, select the Boot item, go to the page, then select one of the items with (Boot Settings Configuration), press Enter, and then select (Wait For.)'f1'if error), press Enter, select disabled, Enter, and then F10 and then Y or'ok'That's it!

Fault description]: The computer's monitor suddenly can't jump, but the computer host has a normal self-test sound. [Workaround:] At first, I thought it might be something wrong with the sound card, but when I opened the case, I took a closer look.

Motherboard coms battery is dead, replace the battery.

Try to completely reinstall the system, if it doesn't work, it may be a problem with the hard disk.

Replace the motherboard battery, enter the BIOS, save it, and basically solve the problem.

Your system is relatively poor, maybe you still use Win7 or Win8 for WindowsXP

Pressing F1 will enter the BIOS settings, and pressing F2 will enter the system from the default settings. At this time, the system time will return to the time when the BIOS was initially created, which does not correspond to the real-time time.

Due to the large number of BIOS versions, different settings can cause different ways of error, but there are a few basic cases:

1. Motherboard battery.

Failure, the battery can be replaced;

2. Turn on the floppy drive, you can turn it off in the BIOS;

3. If the power supply circuit of the motherboard fails, it can be sent to the after-sales service;

4. If the CMOS data is changed due to a virus attack on the CMOS, it can be checked and disinfected.

Of course, the latter two scenarios are very unlikely. If it's the first case, you can buy a simple coin cell battery.

to solve. In the second case, the procedure is as follows: (Take Dell computers as an example).

Power on"del"button to enter the CMOS settings.

main settings interface - > legacy

diskette

The value of item a is changed from [selection to none (some versions can be disable)—press f10 to save and exit—> restart your computer. (If the BIOS is a different version, you can find Legacy.)

diskette

a, just modify it directly! )

The reason for this phenomenon is because of the diskette

A reserves boot space for floppy drive startup, although there is a floppy drive mode in the startup item, but in fact, the current computer does not need to use the floppy drive, so this hardware setting does not correspond to cause the computer to detect errors.

There are 2 reasons why the minimum speed of your fan does not reach the minimum speed required by the motherboard.

1.Open the case to check if the fan is rotating, if it is not rotating or it is spinning very slowly, you need to lubricate the fan.

2.If you do the first point, and you still have this prompt when you boot up, your fan's tachometer may not communicate well with the motherboard, causing the motherboard to fail to detect the fan speed, causing the motherboard to think that the fan is not working.

Then you have to buy an Intel certified standard fan, commonly known as: original fan, only the chip on this fan can provide speed.

Your other hardware is fine. Judging by the alarm sound, the alarm sound of the memory is bad should be "long beeping." Combine.

There was a short pause"

Method:1The battery of the computer motherboard is damaged or the power is insufficient, when the power of the computer motherboard is insufficient, there is no guarantee of the power supply of the motherboard, resulting in the information of the settings in the BIOS cannot be saved, at this time, only press F1 to enter to ensure that the motherboard information is not lost, in this case, please replace the motherboard battery in time;

There is a problem with the motherboard's settings or a new driver is detected, in this case, you should turn off the running driver item in the BIOS settings, the specific method is to press the delete key (del) after booting up, in the first setting, find drive A or drive B, press pgup or pgdn on the keyboard to adjust, set their settings to "none" not to detect, or find the option about "floppy", set this option to "none" not to detect, Finally, press F10 (Save and Exit), select Yes, and the computer can be restarted to solve the problem of pressing F1 to enter the system after booting.

3.It is recommended to uninstall the relevant software, and if the implementation fails, it is recommended to reinstall the system;

4.If the system hard disk is damaged, it is recommended that you back up important data in time, and if it really doesn't work, find a professional to check it.

Many older motherboards are started by floppy drive by default, which is generally set up when buying a computer, but after a long time, there are occasional times when the motherboard BIOS program is homebound or the motherboard battery is out of power, it will become the initial setting, so that you press F1 is skipped. This needs to be reset by finding a clear understanding of the motherboard BIOS, and changing the default first boot to the hard disk as the first boot. As for the size of the fan, it depends on what kind of fan it is, it may also be a power supply fan, or a CPU fan can also make a graphics card fan or a north-south bridge fan of the motherboard.

Then turn on the machine, if the sound is still there, in judging which part of the fan blade is noisy, many ball fans have a long life, but after a long time of aging and lack of oil, the noise will be large, find the problem or oil on, or directly change the fan blade.

Does it show CPU error, the CPU speed is too low, and the BIOS self-test fails. You need to manually change the CPU on F1 or turn off the CPU Fan setting in the BIOS.

Pressing F1 is a motherboard setup issue, and you need to skip the floppy drive to boot normally. The sound of the fan is loud and the dust is cleared.

Motherboard set up. del can be seen on the first page. Just turn it off.

If the fan is loud, change it.

There are two possible scenarios for this reason:

1. If the motherboard battery is dead, then you need to replace a lithium battery.

Second, the settings in the motherboard BIOS are not correct, this will also cause the boot to press the F1 button, in the case that you can operate the BIOS system, it is recommended to first see if it is a problem that the battery has no power. If not, then go to the BIOS, load the factory defaults first, then adjust the items, and turn off the "wait for F1 if error" Chinese in the BIOS, which means that the error message is pressed F1 when booting, that is, set to disabled.

Go into the CMOS to set it up, and it's best to change the motherboard battery.

A tick is the normal self-test sound of the award BIOS motherboard, and pressing F1 is mostly caused by the motherboard's battery being dead.
