The green light of the motherboard is the power indication, if it flashes, it depends on what the motherboard is, it can't be turned on, generally only with the power supply, whether the button is normal, and then it is related to the CMOS, you can put down the power of the CMOS, and then turn it on to try, and then use the chassis button to short-circuit the motherboard directly with a screwdriver.

power directly boot to see.

Faulty memory, power supply, motherboard, any one can lead to this.

Coral secretly helped Shen and Dacheng. Shen learned the truth from the old lady, repented and apologized, took back the coral, and reconciled with the mother-in-law and daughter-in-law.

Common causes: 1. The capacitor of the motherboard is damaged. 2. The monitor has the sleep mode turned on, you can unplug the power cord first, and then plug it back in after a few minutes.

3. If there is a problem with the interface of the signal cable, you can replace the connection port of the signal cable again, and replace the end of the signal cable with the display with a signal cable to connect with the computer host.

If you also experience a failure with memory and discrete graphics, we need to remove the memory module and discrete graphics card, clean and wipe it with a clean eraser, and then carefully put it back in its place. In this case, if you turn on the computer and it still can't be displayed, then you need to consider removing the battery from the computer motherboard, waiting for 3-5 minutes before reinstalling the removed battery and putting it back inside the battery slot.

Take Dell achievement 5880 computer, win10 system as an example, the reasons why the red light of the computer host keeps flashing are as follows:

The red light on the main computer keeps flashing because the computer is performing data read, write and operation, and the computer may be overloaded. It should be noted that the red light will also flash all the time while playing the game.

The red light on the computer host is the working indicator of the hard disk, under normal circumstances, the red light keeps flashing means that the hard disk is working normally, and if it is not flashing, it means that the hard disk is busy, and if it does not flash, the hard disk is not working or the hard disk is broken.

If the red light of the computer host flashes relatively quickly, it is because the hard disk is reading and writing frequently, and the memory may be too small, in this case, you can increase the memory.

In addition, you can also turn off System Restore, although System Restore can save important files and settings on the computer well, but it increases the background read and write tasks of the hard disk, and turning off System Restore can improve the performance of the computer.

This answer applies to most models of computers under the Dell brand.

The computer is just turning on the fan, the monitor is not responding, the red light keeps flashing, and Ken's demeanor must be the computer hardware.

If there is a problem, it is best to use the substitution method to eliminate the problem, and the judgment method:

1. Press the upper and lower case on the keyboard. The light is on, indicating that the graphics card, monitor, and other hardware are faulty.

2. If the keyboard light does not light up, it means that it is a memory, CPU, motherboard, or power supply problem.

Solution: 1. If the keyboard light does not light up, first wipe the memory module with an eraser.

And check the gold finger of the memory stick.

Whether there are burn marks. Replace the memory in the slot.

2. Check the capacitors and resistors on the motherboard, see if the capacitors are bulging, whether there is a burnt smell on the motherboard, and clean up the dust on the main spring source board.

3. Remove the CPU fan, power on and turn on, test whether the CPU has a temperature change by hand, if not, the CPU is not working, either the motherboard is broken, or the CPU is not plugged in properly, and the CPU is re-plugged.
