Generally because of memory problems, you can take down the memory and blow the ashes, and then plug it back in, or try to change the memory, and change the memory slot to try it, most of the memory problems, because there is no "drop" sound means that the hardware has not been monitored.
Problems can also occur with the graphics card, but the likelihood is a little less likely than the memory.

What you said is not very detailed, I heard it very vaguely, that is, your monitor has been confirmed to be fine, right? But,It just can't be displayed.,Or is there a problem with your host.,Or you haven't figured out the problem If it's the host.,I think it's because it's a problem with your graphics card and **cable connection to the monitor.,Or it's a problem with the graphics card.。 As for your fan going off, I don't know what kind of fan it is, whether it's a CPU or a graphics card, or a power supply!
Saying it clearly might work out.

The reasons why the computer display lights up yellow and how to fix it are as follows:
1. If the display cable is damaged, loose or not connected normally, it is recommended to replace the display cable or plug and unplug it again.
2. If the computer chassis hardware failure causes it not to boot, it is recommended to replace the computer memory, graphics card, power supply, motherboard, etc. one by one, troubleshoot the fault and then replace it.
3. The other is the display failure, if you can find another monitor to replace it, you can basically judge the problem. Replace or send it for repair.
Extended Information: A display is also commonly referred to as a monitor. A monitor is an IO device that belongs to a computer, i.e., an input and output device. It is a display tool that displays a certain electronic file on the screen through a specific transmission device and then reflects it to the human eye.
It can be divided into various types such as CRT, LCD, etc.

Causes and solutions:
1. The memory module is loose or damaged.
Solution: Use an eraser to wipe the gold finger of the memory module and reinsert the memory stick; Replace the memory module.
2. Poor contact of the graphics card.
Solution: Same as memory method.
3. The main engine is short-circuited.
Workaround: Clean up the host and replug the wiring.
4. Motherboard BIOS problems.
The motherboard BIOS stores important hardware data, and if it fails, it can cause the computer to not boot.
Solution: Go to the motherboard BIOS settings page and restore the BIOS to the default value.

The power indicator of the computer host lights up yellowSolution:
When we use the computer room, sometimes we can't turn it on, the screen has no display (black screen) or prompts no signal or the display enters the sleep state or sends out a Didi alarm sound, mainly because there is a problem with the host or display, which aspect is specific, just look at the right numeric keypad light "nunlock digital lock" whether it is on.
If the right numeric keypad light is on, but the computer has no display, then there is a problem with the display; If the keyboard light on the 7 on the right numeric keypad does not light up, then there is a problem with the host.
1. Open the main machine cover under the premise of section electricity, as long as the relevant screws are unscrewed, the computer cover can be opened.
3. After pulling out the memory module, use a hair dryer to blow the dust in the host, and pay attention to the cleanliness and hygiene of the host.
4. Change the socket position to insert back into the memory or re-insert it, if it is useless for the first time, plug in the position, try a few more times, pay attention not to reverse the interface, and the memory card can not be plugged in the case of power.
5. After installing the memory card, install the host, and the computer can operate normally when it is turned on again. If you still can't solve the problem, it is recommended to go to a computer repair shop for repair.
6. Remove the motherboard button battery and leave it for more than 5 seconds, then install the battery. Then connect the power supply and peripherals, and try to boot up normally.
7. If you still can't boot up normally, you can unplug the discrete graphics card and install a single memory test.

1. Problem analysis:
When the computer is powered on but the display is powered on but there is no signal or "no sighal" is displayed, it is usually due to poor contact between the memory module or monitor data cable, or the memory, graphics card, display or data cable is damaged.
2. Handling suggestions:
1) If the monitor is powered on but no signal is displayed, turn off the power (if the short press on the power switch is invalid, press and hold the switch until the power indicator goes out or directly unplug the power cord) Turn on the case when the power is off, replug and unplug the memory module, and wipe the gold finger with an eraser in one direction (the back of the thumb fingernail is also fine), and then turn on the power after installation (before operation, you should also touch the wall with both hands to release your static electricity or wear anti-static gloves). If you don't know how to operate, then it's simple: a palm or kick on the chassis is fine (note the location:
The front of the shell on the left and right sides of the chassis without an interface in the back; Attention Tract: Don't push too hard). The above may need to be repeated, and if it doesn't work, you need to replace the memory module.
If you have more than two memory modules, you need to test them one by one.
2) If the above operations are invalid, turn off the power and turn on the chassis, replug and unplug the graphics card, and plug in the data cable between the monitor and the graphics card. If it still doesn't work, consider that the cable or graphics card is damaged, then replace it with a new one.
3) If the host can be displayed when connected to other monitors or the display of this machine is connected to other normal hosts and still cannot be displayed, it means that the monitor is damaged and needs professional repair.

The computer host keeps flashing yellow lights, and the monitor doesn't respond to what's going on.
1. Turn off the power, open the case, clean up the dust, especially the dust of the CPU fan, and check whether the CPU fan is rotating normally. 2. Plug in and unplug the memory, wipe the gold finger part with an eraser, and re-insert it (don't reverse it). 3. Plug and unplug the graphics card, wipe the gold finger part with an eraser, and reinsert it tightly (the buckle should be buckled).
4. Unplug the power cord, cut off the motherboard button battery, wait for three minutes, and reinstall the motherboard sail. 5. If the above operations cannot solve the problem of tansan car, it is recommended to send it to the maintenance center.
There are many reasons for the failure of the computer to turn on the black screen, such as the display is damaged, the motherboard is damaged, the graphics card is damaged, the graphics card is in poor contact, the power supply is damaged, the CPU is damaged, etc. For the treatment of the black screen of the computer, the method of eliminating and replacing is basically adopted, and the principle should be based on replacing and eliminating the most suspicious parts first. >>>More
