The computer turns on blue. There are no words and nothing 20

Recommendations:1Check that the RGB cable is the signal cable on the main unit (the one with the big blue head) and the monitor is secure. If not, please hold it firm.

2.There is a problem with the monitor. (No way, you can't just take the console to check) Check the monitor!

Maybe it's the first one, the wire is not connected well or the wire is damaged, there may be a boot color cast! If it doesn't work, just open the case, take out the memory module, and erase it with an eraser. Just put it in again!

The cord is loose, look at the connection between the graphics card and the monitor.

There are two reasons why the screen appears blue: First, the computer is poisoned, causing the hardware to boot abnormally and display a blue screen. Second, the computer hardware is loose, and the boot cannot operate normally, resulting in a blue screen.

Based on your description, the possibility of computer poisoning is not large, it should cause a certain component to be loose when you carry the computer, poor contact, and cannot start normally, the most common two parts: one is the memory card, the other is the graphics card, these can be checked by yourself, unplug and reinsert, there should be no problem.

1. If you want to press F1, it should be that the BIOS battery is dead or there is a hardware change! The second is that the boot sequence is set incorrectly. Battery replacement may be considered.

2. The screen is blue after startup, it should be a system problem! There is a virus that is a symptom of this, it can't be infected by the place where the computer is repaired!! This is still a reinstall system!!

It should be the memory card, the problem with the graphics card is loose.

After an abnormal shutdown, the computer may have a blue screen!
