Exposure to sunlight is likely to be caused by moisture. You can go to a nearby computer repair shop to clean up the dust and reinstall the operating system. It's going to be fine.

Dear users, hello!

Find the most authoritative, professional answers.

There are two places, one is the heatsink and the other is the hard disk, because the hard disk will have a run-in period when it is first used, so it is normal.

The sound of the hard drive turning, all like that.

Either solid-state drives, mechanical hard disks will be more or less some, the sound of workmanship and sound insulation is smaller, and the worse is bigger.

It does not affect the use.

The problem with the hard disk is whether it has been dropped and touched Try not to move it in use, which will cause the hard disk head to scrape the disk.

The charging time is too long, and the driver is broken.

Has this computer been in water before? My computer can still be used and charged after it gets into the water, but it can't be charged after it is turned off. Finally, the check said that the computer's IO port was broken.

,,The computer can't turn on, and the weather is not very objective. Weather may be a trigger, but the underlying problem should be the computer itself. In this case, it is mostly due to the electrodes of some plug-in parts inside the computer, or the oxidation of the gold finger electrodes of the memory and graphics card is more serious, which will cause poor contact failures as soon as there is a wind and grass.

After the power is turned off, check it.

If it is due to weather conditions, consider whether the motherboard is short-circuited due to moisture. There is also the reason for the aging of the computer.

First, depending on the power supply, sometimes it is powered on, sometimes it is not, it should be that the electrical appliances are aging or whether the wiring is too dusty, it is recommended to repair the electricity to clean up or check it.

Second, the humid air environment will also affect the power supply and shorten the lifespan.

Third, if you really can't change the power supply, it's not expensive.

It's still a bad place to touch, and it's better to fix it.

This is because the graphics card has accumulated too much dust, and the motherboard is too, just remove the host and clean it.

This is not a weather problem, it may be caused by poor line contact, just take it for maintenance.

If it is the weather, consider whether the motherboard is damp, and then consider whether the hardware is in poor contact and whether there is more dust in the fan

It may be that there is a problem with the socket connection, I have also encountered it, and then I changed the power cord and solved it!

Look at whether the fan of the power supply is rotating, if it doesn't, most of the time you have to change the power supply, how many years has the computer been? For about 3 years, consider changing the power supply

This has nothing to do with the weather, you need to clean up the garbage from the fan.

When the computer is old, it is best to clean up the dust before installing it to avoid poor contact.

It is not a big problem with the weather, it is recommended to check the fan circuit.

It may be that there is a problem with the wiring, the connector is loose, or it may be a problem with the fan, it is recommended to go to the maintenance office to check!

There is an impact, it is uncertain, it is possible that there is static electricity, or it is possible that you collect too much dust, and the specific situation is analyzed, and the machine is brought to me to check.

No, move to the shop to fix it, it can't have a problem with the weather.

The computer does not turn on for two days, and the fan does not rotate because of the weather.

If the contact is poor, this problem may occur in the future, so it is necessary to clean up the dust at ordinary times.

It's not a big problem, it's a bad contact, just plug the memory module and graphics card back in.

It's not the weather, it should be the best line contact.

Possible reasons are:

1.The mains voltage is insufficient.

2.Bad contact with external electricity.

3.If you don't use it for a long time, there is dust and moisture in the chassis, UMC, and it won't be turned on. Later, the moisture evaporated and the machine was turned on.

Suggestion: Dust removal in the chassis.
