What should I do if my computer won t light up?

Hello landlord:

I don't know how the landlord's hands-on ability is, judging from the landlord's description, you can try to operate like this first:

3: You can turn on the self-test, congratulations on passing, no, continue.

4: Observe whether it is alarmed, eliminate memory faults, if the landlord confirms, you can skip this step 5: Remove the hard disk, only keep the basic skeleton such as CPU, motherboard, memory, power supply 6:

Click! Motherboard power pins, observe to be able to boot 7: Yes, then the failure on the hard disk, you can reinsert the cable, or try to replace the IDE slot to solve 8:

If not, unfortunately, the motherboard may be over, send it for repair or replacement, hehe The above steps can help the landlord to eliminate and confirm the fault point step by step.

If there is any problem in the middle, the landlord can give me feedback on the problem.

First of all, it is necessary to ensure that the jumper and the power cord are all connected

You turn on the speaker, and then click on the power, if you can hear the sound of entering the system after a while, that is, the sound of booting, that is, the graphics card is broken, if it is not the graphics card is broken, there has been no sound when booting, then you have to take a closer look at whether the capacitor of the motherboard bursts, and there is a problem with the hard disk, unplug the hard disk cable, click on the boot to see the BIOS boot screen No, if you can, it is that the power supply is unstable or the hard disk is broken, if it still doesn't work, that is: your CPU is broken.

Do you horn alarm when you turn it on? If there is an alarm, the fault can be judged based on the alarm sound.

If you don't call the police, it is recommended that you remove all the hardware, keep only the CPU, turn on the computer to see how the situation is, and listen to the alarm sound.

Then install the graphics card, memory, hard disk, little by little. See which hardware is broken.

If it's all right, there's something wrong with your BIOS, or your motherboard's battery is dead.

Your hard drive has bad sectors! I used to have your situation, forced to cut off the power and reboot caused by bad sectors, it is recommended that you change a hard disk, you can use it if you don't change it, re-test the hard disk, I hope it can be used for a longer time. I took the hard drive with bad sectors to bt, and I don't feel sorry if it's broken anyway.

If it doesn't work, just change the graphics card and take a look.

It's definitely a problem with the motherboard.

Apparently the operating system collapsed.

Let's reload.

1. This is a host problem, also known as not lighting up.

2. The main reason lies in the hardware, such as: poor contact, memory, graphics card, motherboard and other problems.

3. Solution:

A: Disassemble the side panel of the chassis and reseat the memory, graphics card, hard disk data cable, power cable, and 20P power supply cable.

b: If the machine still doesn't light up, for example, wipe the gold finger of the memory, insert it into another slot, and then turn it on.

c: Troubleshoot the hardware by unplugging and replacing the memory and graphics card, and then replace it.
