1. The graphics card alarms. If your computer's graphics card is not in good contact with the motherboard, it will happen that your graphics card is broken.

2. Memory problems. This can also happen if your memory is not plugged in properly or if the memory is broken.

Generally, when we encounter computer hardware problems, it is recommended to use the elimination method to solve them. One by one, there is always a hardware problem.

That's the computer holding the wrong one in the system.

Open the chassis to remove the dust and plug each component in again.

2. Power-on without display failure, this situation is caused by loose aging of components or chip virtual soldering damage, common reasons: loose memory or memory itself has problems, reinsert the memory or change the memory to try; The power supply chip of the motherboard is soldered or aged, the screen cable is loose or the motherboard short-circuits the power supply circuit of the screen; The virtual soldering or damage of the BGA packaging chips of the graphics card, south bridge and north bridge can be solved by professional BGA packaging welding equipment and technology soldering or replacement;

3. The machine will be affected by moisture and shock or long-term overheating will lead to this situation, if you have experience in disassembling and assembling the notebook, you can disassemble the machine to detect whether the internal accessories are loose or the interface falls off, if there is a corroded or burned place, you need to replace the new motherboard to solve.
