Reason analysis:

1. Usually when the computer is turned on, the first step is to perform a device self-test. If the screen is stuck at the motherboard LOGO picture, in most cases the hard disk test has not passed. You can try to replace the data cable of the hard disk. If there is no cable, you can also try to transfer the data. Swap the two ends of the cable, and then change the connector on the motherboard. (If it is a notebook, you can try to remove the hard drive, and then see if the LOGO interface can pass, you can determine whether it is caused by a hard drive failure)

If it is caused by a hard drive, you can plug the hard drive into a desktop or other laptop to check. If it still doesn't work, you can just replace the hard drive.

2. The motherboard BIOS is wrong. Some motherboards have anti-intrusion mechanisms. If you have recently replaced accessories, it may also be caused by an error in the motherboard BIOS. The solution is to turn on the computer and press the DEL key to enter the motherboard BIOS, initialize the BIOS setting information, and then press F10 to save and exit and restart the computer.

3. Check whether there are external devices connected to the machine. External devices such as USB flash drives, mobile hard disks, etc. may be plugged into the USB port of the computer and forgotten to be unplugged, causing the motherboard self-test to fail. The solution is to unplug the extra external devices and restart the computer.

4. Check whether the keyboard and mouse are connected reversely. This refers to the PS/2 interface keyboard and mouse. Many people are careless and plug the keyboard and mouse interfaces backwards, causing a self-test error when starting the computer and causing the screen to freeze. The solution is to shut down the computer first and reconnect the keyboard and mouse. Usually the purple port is the keyboard and the green port is the mouse.

5. Check whether there is a CD in the CD-ROM drive. Sometimes some CDs will cause the detection to fail!

The above is an introduction to the reasons why ASUS notebook Win7 is stuck on the ASUS LOGO interface when booting. There are 5 reasons that may cause this situation, and the possibility of hardware failure is relatively high.
