Miner's video card light on, fan not working

1. Remove the fan and try to use the battery. If you don't turn the fan, it's broken (change the fan), if there's something wrong with the graphics card

2. If the temperature does not reach the start limit of the video card fan, it will not rotate naturally. You can try to turn on the large stand-alone special effects. If it is fully open, it will rotate naturally. If it is not turned on, the video card fan may be broken

3. It's the same with mine. It doesn't work for 2-3 months. If I use it again, I'll have no signal. If I unplug the memory mole, the video card fan will turn and plug it in, and the display will not turn. What's the problem?

5. If the graphics card doesn't read out, you should first confirm whether it is plugged in tightly, then confirm whether external power supply is needed, and then confirm whether the display cable is plugged in the
graphics card socket. Finally, power on and test the machine. If it doesn't work, it's usually a problem with the
motherboard or the
graphics card, or send it to the repair station. Hurry up

6. First, you need to make sure the power is working. In the repair shop, it's to find another one and try each other. At home, there is also a way: take 3-4cm wire. Peel both ends. Hold your computer into a U-shape, and unplug all the cables related to the power supply of your computer: motherboard power supply, CPU power supply, and hard disk power supply. Power the optical drive, and then connect the power supply. Holding the power supply interface to the motherboard in hand, there are 20 holes and 24 holes. No matter which one, observe the color of 20 or 24 hole wires, and find that there is only one green wire and many black wires. There are U-shaped wires connecting green and black wires to see whether the power fan will turn. Try several times, if turn, the power is normal, if not turn, the power is broken. In the case of making sure that the power supply is good: first, take down the CPU and install it carefully, that is, move it. have a try. Look at the CPU power supply, next to the capacitor, whether the appearance is normal, touch by hand, hot? Secondly, unplug the main board power supply, and try to plug it in several times. Finally, take off the main board battery, wait for a while, and install it. Sometimes the power switch of the computer is broken. Unplug all the cables connected to the chassis in the lower right corner of the motherboard, and connect them with a screwdriver. The two pins on the motherboard are indicated as power. Look carefully, it's very small on the motherboard.

7. Before all fans are turned on, turn off the computer, power off the computer, install the hardware again (check whether it is installed properly), and check whether the wire is connected well
do not connect the hard disk and external equipment first, and then turn on the computer to check. If it is the same, install the hardware on the motherboard to other motherboards to see if it can be turned on normally. If it can be turned on, it indicates that there is something wrong with the original motherboard; If it doesn't light up, there is something wrong with the hardware on the motherboard

8. The computer can't be turned on
the computer can't be turned on under the following conditions:
1. There is no response after pressing down the power supply:
generally, after the computer is turned on, the power supply will start first, and then the power fan will turn. If the power fan doesn't turn and the power indicator of the computer doesn't light up, the power supply may be faulty and the power supply needs to be replaced. However, it is also possible that the motherboard is damaged and the circuit cannot operate, resulting in the failure to start the power supply
2. After the power supply is pressed down, the fan of the power supply turns, but the computer doesn't respond, and the screen turns black:
this problem is most likely e to the damage of the motherboard or the failure of the
CPU. After the general computer is turned on, if the motherboard and
CPU have no problems, it will enter the
BIOS
startup program to detect the motherboard and peripheral devices. If the computer doesn't respond, it means that it can't enter the
BIOS
startup program, then it may be the motherboard or
CPU
fault. To find out which fault needs cross test, or use test card to find out the fault point
3. After power on, the computer starts, but there is a special sound:
at this time, it means that the computer has entered the
BIOS
startup program, but there is a special sound e to the failure or loss of peripheral devices. The most common peripheral problem is that the memory or display card is not inserted properly. You can try it again. The test card can also be used to find out the fault point
4. After the computer is turned on, the computer stops or the speed is very slow when checking the hard disk:
this condition indicates that the hard disk may be damaged or the optical disk drive is incompatible
some discs may conflict with the hard disk or CD-ROM drive, which may cause the hard disk to stop or slow in detection. You can remove the conflicting CD-ROM drive to improve the situation
5. The computer replies that there is no operating system:
this condition may be that the boot disk of the hard disk is damaged, or the boot disk code is damaged by a virus. If it is the former, you can use the hard disk repair program to try to repair or replace the hard disk. If it is the latter, you can use antivirus software to remove the virus, or to reparticate and format the hard disk, and then recharge the operating system
the following is for your reference
the power supply has a high probability of aging or failure
it is recommended to test and check the power supply first
the power supply will cause insufficient frequency with the aging of service time
and cause unstable startup
this kind of situation is also quite common, especially when we add new equipment to our host computer, such as replacing high-end graphics card, adding burner, adding hard disk, it is easy to appear
it is recommended to use a higher wattage test than your power supply

9. The temperature measurement does not reach the temperature of starting the fan. Watch the video or play the game

10. Maybe the chassis switch is broken. Take a look at the cable connected to the motherboard. If there is a power
SW, unplug it, and then connect the two pins with a screwdriver. If the machine is turned on, you can't even turn on the power fan, which means that your computer is not turned on at all. If it's not a switch, it's a power problem. Other problems won't lead to this phenomenon
