Anonymous users2024-02-07First of all, I declare that my computer has been having this problem for a while, although sometimes I don't want to care about it, but once I couldn't turn on in the morning, and it turned on magically in the afternoon) I have two solutions to solve this problem.
The first is that you need to remove all the hardware on the motherboard of the host (that is, the graphics card, memory sticks, etc., as well as the CPU fan and CPU) and cables (the wires connected to the motherboard), and then remove the batteries on the motherboard, wait for three to five minutes, and install them all in order, the order should be the CPU heatsink memory module The cable on the motherboard, remember that the cable of the heatsink is plugged in when connecting the cable on the motherboard, and then all the hardware such as the graphics card is plugged in and screwedFinally, put the battery on, and it's OK.
Second, if you feel that the above steps are a bit complicated, or the display screen is not reflected after installation, it is recommended that you send it for repair. About 30 bucks.
There are many reasons for this problem, such as the aging of the computer hardware or motherboard, or the fact that it takes too long to clean the hardware when you take it out. There are many, many more, so if you don't understand, just ask me.

2.Open the main cover, check the motherboard, graphics card, and power supply for any abnormalities or odors, and check whether the memory module, graphics card, hard disk cable, and CPU heatsink are loose.
3) Unplug the graphics card and memory stick, find a clean cloth and an eraser, a little alcohol, use the eraser to oxidize the gold finger of the graphics card and memory stick, use the eraser to erase it again, pay attention to the strength, and then wipe it with a cloth with alcohol.
4) Clear the dust, memory modules and graphics card slots in the case, motherboard and CPU heatsink, and pay attention to the need to use a soft brush to clean it, don't fall into it!
5) Clean up the dust of the CPU cooling fan, if there is a condition, it is recommended to replace the CPU silicone, but you must be careful when disassembling the CPU fan, you must not pull it hard, Intel's original rotating buckle is gently pulled up, and other heat sinks refer to the manual;
Complete the above steps, install all the accessories, check if the installation is in place, and then turn on the test! Generally, the probability of memory modules is large, so you can focus on checking the memory modules first! If it can't be solved, it may be a hardware problem, and you can only go to an after-sales or repair shop!
Seeing that you have changed so much, even if you haven't changed the motherboard and hard disk, maybe a capacitor has exploded! It's so annoying, you might as well bother it a few more times!
There are many problems with the computer booting up, there may be graphics card, memory graphics card, and it may be a hard disk, as well as dust, in the absence of any instruments and tools, it is impossible to know at once that it is a problem that can only be eliminated. First of all, you observe whether the motherboard light is on, if it is on, it means that your motherboard is powered on, and then see if the CPU fan, graphics card fan, and power supply fan are turning, if the above are running, but the display is not on, we can follow the steps to exclude. First, check whether the connection cable between the computer and the monitor is loose or broken, I once encountered a buddy connection cable that was bitten by a mouse, and I didn't find the reason for looking for a long time. >>>More
The motherboard is a little more likely, or it may be a problem with the graphics card, you first unplug the graphics card and clean it up, as well as the memory, and try again.
There are several possibilities for this problem,One is to make sure that your host can start,Change to other monitors can display no,It can be the machine number,The display is broken,The second is that the machine itself does not start automatic shutdown,Is it able to hear the sound of the drop after shutting down or no sound shutdown,You can hear the sound shutdown then your switch may have a problem,Change clothes is good,If you can't hear the shutdown,That's not started,Then look at the memory,Graphics card,And other hardware。 If you have tried all of the above, you can't open it.,Maybe it's a problem with the board.,By the way, there's ash.。
Summary. The boot display shows no signal, but the host has lit up Hello, I'm happy to answer for you, < >>>More
