If the display light is not on, there is no signal output. If the keyboard and mouse are not on, they have not been self checked. From this, the motherboard and cpu are not working. You can unplug the video card, memory, hard disk, and CD-ROM drive, and try to turn on the computer. There should be an alarm. If there is no alarm, try to power off the cmos. If the discharge is still invalid, you can send it for repair. If there is an alarm, turn on the video card,The golden finger of the memory is polished. Try to install it one by one to see if it is faulty!
The red light is the hard disk light.This indicates that your host has not started to read the hard disk.Open the chassis and reseat the memory, graphics card and various cables from the motherboard
