HP notebook suddenly blurred screen, HP notebook suddenly blurred screen, what is the problem?

The graphics driver has been destroyed! Do you want to buy another ???

There are 4 that may cause a blurred screen. I'll tell you about them one by one. First, take down the memory, wipe it clean and reinstall it. This is step 1. Then deal with the splash screen.

The first, the simplest, is the system problem, the driving problem. This is relatively easy to solve. Repartition the hard disk, reattach the driver, and go to the official ** drive.

The second, the screen. The screen will cause a blurred screen. If there is a problem with the high-voltage plate, it will cause a blurred screen.

The third, the graphics card. The graphics card of the motherboard is soldered. If the graphics card is bad, it will cause a blurred screen. The hp has a graphics card door. It's because of the graphics card.

Fourth, the graphics card controller in the northbridge is broken, which will cause a blurred screen.

Maintenance ideas. Let's get the easiest first. System, drive.

The fault is still there. As far as the external monitor is concerned, the problem of the screen is eliminated, and if the fault persists, you need to go to a professional maintenance place to repair the graphics card and the north bridge on the motherboard. BGA soldering needs to be done for the graphics card and the northbridge.

I have also seen the phenomenon of a blurred screen on the computer, generally caused by the destruction of the graphics card driver, or improper resolution settings, as long as it is repaired, it can generally be solved, but static electricity will also lead to a blurred screen, at this time, only turn off the notebook, take off the battery, and press and hold the notebook on/off key to solve it.

Take a look at the external monitor, if the external monitor is normal, you can basically determine that it is the LCD screen or cable or high-voltage package problem.

Let's tell the landlord like this, the laptop screen is because the power supply of the booster plate is unstable, and you swing the monitor up and down, and it is estimated that it can return to normal.

You can rest assured, the LCD screen is not broken, it is the problem of the booster plate. The booster plate is guaranteed for one year, and it is estimated that it is overwarranted. It can only be repaired for money.

This accessory is about 500 in customer service and about 300 in the electronics market. If the landlord is reluctant to spend money, it doesn't matter if it's just like that. I did this for two years.

If you don't repair it, the frequency of the screen will get higher and higher, so it's good to get used to it.

It should be a system problem, the system is unstable, and it has nothing to do with the machine.

Either the screen line is a problem with the high-voltage board.

System problems, system instability.
