A common problem with ASUS computers.

I don't know when, just when it was turned on, let you enter the BIOS, this stalk has been for decades, I really don't know what kicked the head of the person who quietly blew the ASUS computer motherboard.

The landlord is still an old motherboard.,If it's **,There will be a cooler picture.,Don't look cool.,The essence of the branch slip is the same.,It's to let you enter the BIOS.。

ASUS motherboards are synonymous with instability, and seeing this, many people must jump out and bravely defend ASUS motherboards. I asked, can you solve the ASUS motherboard at the time of boot at every turn, stop at the landlord** before entering the BIOS? It's okay not to laugh at the scum, right?

Don't ask, landlord, you have to enter the BIOS and exit to start, this is the stalk of ASUS motherboards, other brands, this problem will not appear. Unless the battery is dead and the hard drive is broken, it will appear and let you enter the BIOS screen. Of course, Dell motherboards, if you change hardware, will also pop up asking you to enter the BIOS screen.

That is to say, it was wrong for the landlord to choose the ASUS motherboard, and the solution is to change the motherboard, and resolutely do not want ASUS.

Prompt and frankly said that there was a RAID in this computer group before, and now the RAID information is missing, requiring you to reset or restore the default - if you can find the specific RAID settings, you can change it back alone, and it is not troublesome to find the default of the recovery slag.

You don't need to have this situation for a long time, see if the power supply is plugged in, check it is fine, and hand it over to a professional computer repairer to take a look.

When I encounter this kind of problem, I always reinstall the system.

This interface means that the BIOS has been reset, and you can use Load Optimized Defaults only to let the computer boot back to normal.

In addition, given that the display does not light up, it means that the coin cell battery on the motherboard is almost out of power. Because the button battery on the motherboard actually does not work when it is turned on, but converts alternating current into direct current to work, so if the computer is turned on frequently, the power consumption of the button battery is almost negligible, like my computer has been used for more than five years, and I have often turned on the computer in the past five years, and there has been no situation where the button battery has no power.

Check the socket difference, Li computer sleepy Zen power supply detection only needs to short circuit "green" and "black" two wires, the power supply "ps" and "on" end of the green wire and grounding short circuit that Wang Qingchen can.

It is possible that the system boot file is corrupted or missing. At this time, we need to make a USB flash drive boot disk with other normal computers, and then restart the computerMost of the Lenovo computer models quickly press F2 when the Lenovo logo appears on the boot, press the up and down keys to select the startup items related to the USB flash drive. After entering the desktop, open the [All Programs] [Boot Repair] [NTBont Boot Repair Tool] on the desktop, click on the C drive, then click [Start Repair], and finally restart to see if it can boot normally.

There may be a problem with the hard disk partition table. If the computer is originally Win10, you want to change it to Win7 system, but when you install the system on a USB flash drive and boot it in Legacy mode, you don't change the hard disk from GPT partition to MBR partition. Enter the USB flash drive PE system, open DiskGenius, right-click the hard disk where the system is located, change the GPT partition to the MBR partition, then click [Save Changes], and finally restart the computer.

It is possible that the hard drive is damaged. If you can see the hard disk when you enter the boot of the BIOS, you can try to repair the hard disk with a tool under the PE system of the U disk, and if you can't fix it (the drive letter is displayed, but it can't be opened), you can format the hard disk (it will erase all data); If you can't see the hard disk in the boot item or can't enter the USB flash drive PE system anyway, then you need to buy a new hard disk.

I can't read the hard drive data, so it should be fine to reinstall it.
