The rules for installing a new device are quite simple.
- The new card is placed in a regular place and inserted into the slot.
- The surface of the chips, CPU and main chips are cleaned with an alcohol wipe.
- Thermal grease is applied to the dry and clean surfaces of the chipset and CPU.
Important! On pasta is not worth saving. Cheap thermal grease has a thick consistency and forms a fairly thick layer under pressure. Or vice versa, a cheap product is extremely fluid and dries quickly. Expensive thermal grease forms a thin, uniform layer with a high service life.
After applying the heat-conducting layer to the card, a protective cover is installed. At the same time, you need to make sure that the thermal pillows fit exactly on the CPU and chips.
Integrated Graphics Challenges
In most laptops, the display is served by a built-in (integrated) video card . This is a special chip, in case of malfunctions of which can be observed:
