Try unplugging it and plugging it in, and the problem will be solved.

The usual practice is to blow dust instead of sweeping, using tools such as leather tigers, because when sweeping, it may touch sensitive parts such as motherboards and CPUs, and a small dust may cause short circuits in integrated circuits, which can cause various problems, so ask professionals to check what the problem is, and it is recommended not to blindly get it.

The graphics card is not plugged in properly, so plug it in again.

This world of grinding is to show the network card booted.

This is a physical problem, the temperature is hot and cold, the lubricating oil in the fan bearing is relatively cold when it is turned on, so it will solidify, the fan rotates with great friction, so there is noise, when it rotates due to friction heat, and then the oil in the bearing begins to lubricate, so the sound is gone, don't care too much, it's okay.

There's too much dust.

Let's change the fan, ten bucks.
