The screen is 50 when it is turned on, and the screen is blurred when it is turned on

Hello landlord!

Your problem is that the graphics card is broken, and if it's not serious, it's barely okay to browse the web, but it's not okay to play games. It's usually not good to fix, but you can try. Especially second-hand graphics cards, if you are not careful, they will break, and second-hand graphics cards will be good if they are used for a year.

I suggest you go and buy a new one.

If you still have any questions, please add or send me a message, thank you!

There are two possibilities for your question:

1.If the graphics card is damaged, it is generally believed that the motherboard's power supply filter ripples are large and will be damaged. It is also possible that the graphics card has poor heat dissipation.

2.If the motherboard is damaged, it is generally believed that the part of the motherboard that supplies power to the graphics card is faulty.

It is recommended that you use an alternative method to find a friend with a good computer to eliminate them one by one and find out the bad problems!

The screen is likely to be a problem with the graphics card.,You can go to the computer city to fix it.,The highest acquaintance takes it.,Otherwise, it either means that the graphics card needs to be replaced.,It's going to kill you at the end.。

It may be that the graphics card has broken solder joints, no need to replace it, find a repair solder, and get it done with a soldering iron, about 20 yuan is about the same.

It should be that the graphics card is damaged, and I've had that happen to me. But it's not a blurred screen when it's turned on. After playing for a while, the screen was blurred, and then I asked a friend who had studied computers, and he told me that it was the reason for the graphics card, and it was now good to change the graphics card.

The vase is usually made of memory or graphics card.

1If you are a discrete graphics card and there is an integrated graphics card on the board, then unplug the discrete and use the integrated one.

2If you have 2 pieces of memory, unplug one and try it.

3. If possible, it can be changed one by one.

80% is caused by the graphics card. You can remove the graphics card to see if the fan is spinning well and how the heat dissipation is. If you don't have a discrete graphics card, you can only go to the one where you installed it and ask him to help you take a look.

If there is a problem with the graphics card, try to clean it, or try to ...... it if you change it

It should be a problem with the graphics card. You're a discrete graphics card.

Isn't your external monitor the same resolution as the one in your own computer? Your problem is probably still a graphics card problem, because the external monitor interface is an analog signal, and your original screen is a digital signal. Let's see if you can replace it (the original of the general discrete graphics card can be replaced), and try to change it.

In fact, you should not disassemble the screen after the screen, and you should take it to the warranty (if you are within the warranty period). It's also possible that there is a problem with the matrix circuit of your screen, resulting in a blurred screen.

One possibility is that there is a problem with the graphics card driver, reinstall it.

Another possibility is that something is wrong with your hardware.
