The computer turns on without a whistle and the monitor does not light up10

If the graphics card is okay with the motherboard.

Doesn't there be any response at all when you boot up?

If you don't have any feedback, you have to think about the motherboard, because if you can see some interfaces, it means that the board is fine.

Also, try a change in your memory, or rub the gold finger part.

There's too much dust in your computer or you haven't touched the wiring in it for a long time! If you use it, the computer will automatically shut down and get back up! That's usually a CPU fan problem!

CPU generally has a self-protection setting, generally more than 60 degrees automatic power off,,, check if your CPU fan is broken, if it is not broken, then remove the fan to see if there is silicone in the contact point between the fan and the CPU, if not, you go to repair the computer there to add or take some from them to add it yourself, add it yourself and see if it is okay, if it still doesn't work, you clean up the computer dust! Then reinstall all the slots in your computer!!

Hehe,Memory thing,Unplug it and try to change the position,That's how I solved it.,If it's Lenovo,Tsinghua Tongfang and other computers directly consider changing the memory。

How many memory sticks are you? If it's two, one of them may be broken.

If there is only one memory module, it may be that the contact is not good (wipe off the gold finger), and then it is not good, then it is a problem with the hard disk.

In general, no honking is a memory issue.

Graphics card issues... All of the above are fine. If your computer's graphics card is integrated, that's it. I had to buy a graphics card...

Unplug the graphics card, clean up the slot, and plug it in again.

Hello, I'm glad to serve you, there are two reasons why the computer starts up with sound but the display screen does not light up: the line is the blue line with two screws behind the computer is loose, this is connected to the graphics card on the host, you find this wire on the back panel of the host and behind the display, and tighten the screws on the left and right sides of the wire 2The display screen is damaged, resulting in the inability to image the display, but the host is turned on, so the computer has sound and no picture, in this case, the display screen needs to be repaired.

1. If the computer monitor does not light up, it may be that the monitor is broken, and you need to check whether the monitor is working properly. 2. It may be that the graphics card is broken, and you need to replace the graphics card or install the graphics card driver. 3. It may be that the display interface of the motherboard is not in good contact, and you need to check whether the display interface of the motherboard is loose.

4. It may be that the memory or graphics card is not compatible with the motherboard, and you need to replace the compatible memory or graphics card. 5. It may be that the motherboard is broken and needs to be replaced with a new motherboard.

The display circuit is damaged and cannot be turned on normally; 4.
