Causes and solutions of virtual welding;
1. If you can still access the system, try to install the official driver first to eliminate software failures.
2. The NVIDIA problem graphics card for notebooks has a large calorific value, material problems and easy soldering. Solution: The simple method is soldering or replanting, which completely solves the need to replace the brand-new and improved graphics card.
3, notebook heat dissipation is not good, such as fan blockage, resulting in heat circulation can not go out. There is also a poor heat dissipation effect of the radiator tube. The heat conduction effect of heat dissipation pad and heat dissipation silicone grease is not good. Solution: clean and dust the notebook, add fan lubricating oil, change the fan for long rotation, change the pure copper cooling pad and so on.
4. Violent vibration leads to virtual welding. Solution: solder the graphics card or transplant or even replace the graphics card. If the motherboard is padded, it needs to be replaced.
