What is the reason why the CPU fan is normal after booting, but the hard disk does not feel the temp

1. There is no display after booting, and it has nothing to do with the hard disk! If there is a problem with the hard drive, there will be a prompt saying that the hard drive cannot be found or there is a problem during the self-test.

2. Check the connection of the monitor signal cable first! If there is no problem, then it is almost a problem with the CPU or motherboard power supply part or the northbridge chip.

Because when the computer is turned on, the system self-tests the CPU first! After that, there are the most critical parts such as the power supply of the motherboard and the northbridge. Then there are the memory, graphics cards, and finally peripherals such as hard disks and optical drives.

3. It is recommended to send it for repair. Or you find a CPU that is supported by the motherboard and replace it with it.

First of all, you should listen to whether the machine has an alarm sound, 1 memory alarm. 1 sound, the sound wave is relatively long, the graphics card alarms, 2 sounds, the sound wave is urgent. If there is no response, it should be that the CPU pin is bent, or the fan is not tight.

If the CPU is not detected here, it will not detect the hard disk. Problems that seem to be there will be escalated after entering the system. A little personal advice, I hope it will be helpful to you.

When the power supply of the monitor is normal, if the display does not respond after powering on. There could be three reasons for this:

1.If the memory module is not plugged in properly or is too dirty, you can clean up the dust on it and reinsert it.

2.The solution to the graphics card problem is similar to that of the memory module.

3.The motherboard burned out.

You can check them out one by one.

You look at whether the cable is normal, and if not, check whether your monitor is in good condition.

Look at the connection cable of the monitor, and the power light, and whether the monitor is turned on.

Is the display plugged in?

It is not stated whether it is a desktop or a laptop, and the reason for the high temperature is also different. The analysis is as follows:

1. Desktop:

1. The space in the chassis is large, and its hot and cold air flow exchange is far better than the narrow space of the notebook. Under normal circumstances, the temperature of the hard disk should be below 40;

2. If the temperature is too high, it is usually caused by the poor heat dissipation effect of the chassis and the heat accumulated inside cannot be discharged normally. To check if this is the case, you can add a case exhaust fan to improve the heat dissipation conditions.

3. When the ventilation is strengthened, the temperature of the hard disk is still very high, mostly because there is a problem with the hard disk itself, check the working status of the hard disk. You can also install a hard disk radiator to force cooling;

2. Laptop:

1. The temperature of the hard disk of the notebook can usually reach 40 due to the poor heat dissipation conditions in the machine. When it reaches 60, the hard disk reads and writes data is prone to errors; When more than 65, the hard drive does not work properly and may be damaged;

2. Therefore, the heat dissipation problem of the notebook should be paid attention to. If you feel that the keyboard is hot, it is best to stop the computer and let it cool down for a period of time before using it to avoid artificial damage to the parts;

3. The heat dissipation problem of the notebook is more prominent, if it is a long-term game, it is best to install a notebook radiator to assist it in cooling down and prolong its service life.

Generally, the normal temperature of mechanical hard disk is lower than 50 degrees, if the temperature of the hard disk is higher than 55 degrees, it means that the temperature of the hard disk is high and the cause needs to be found and dealt with.

Reasons why the hard drive temperature is too high:

The "physique" of the hard disk itself, such as some older multi-disk hard disks, tends to generate higher heat.

A high-end discrete graphics card is used, and the heat from the graphics card is blown to the hard drive.

The case air intake is blocked, and the cold air inflow is not smooth.

Solution: Clean the hard drive surface and the air intake of the case from dust.

Install the drive away from the discrete graphics card.

If possible, a large-diameter silent fan can be installed at the air intake near the hard drive bay.

What is the temperature of the hard drive? Open the case for a while and measure the temperature.

The machine is overheating.

1. Use disk cleanup to clear the system junk files.

2. Start --- running--- enter msconfig and uncheck all the unnecessary enablement items (such as msn qq, thunderbolt, emulet, virtual optical drive, etc.).

3. Detect and kill viruses and malware. Turn off real-time monitoring and keep your virus database updated and disinfect regularly.

4. Check whether the heat dissipation vent is clean.

5. Whether the ambient temperature is too high.

6. It is recommended to buy a *** heat dissipation bracket to help the laptop dissipate heat 7. Close some useless running programs to reduce the burden on the fan8. Update the driver of the heating part (such as the graphics card driver).

9. Reinstall the system.

10. Contact the service station engineer to help do a dust removal, cleaning and testing of machine parts.
