Video Card and system problems

 

Today, I was commissioned by someone else to solve another system problem. Here I will summarize it for future use.

Specific symptoms: After the monitor is turned on, the system can be started and the black screen is displayed suddenly during use (the screen is a 19-inch LCD card yundai, and the graphics card is Ming Xuan)

Historical symptoms: the video card fan has been on strike, and the machine will automatically restart after running for a period of time. After the fan is changed, it will return to normal again.

Steps:
1. the problem still persists after the monitor is changed, indicating that the monitor is not faulty.
2. Open the music player after the player is turned on, and wait for the black screen to appear.
Music, indicating that the problem is purely a video card (memory failure may also lead to a problem with the display black screen), software or hardware needs further troubleshooting;
3. Reach out to the display card fan, and the fan works normally. Outbound
There are three alarms on the chassis (No buzzer is displayed on the display card) when the fan is close to each other.
(I do not know the specific reason)
4. the motherboard does not contain an integrated video card. After the operating system is re-installed, the tomato garden can recognize the host, video card, and nic.
You only need to install the sound card driver. At least it indicates that there are no major problems in the hardware functions of the video card, but the stability is poor,
It may be caused by software conflicts, but it cannot be determined.
Cause: After the system has been installed before, it is customary to install the driver on the motherboard and on the video card, regardless of whether the video card or motherboard is already driven.
In addition, the specific driver versions are diverse, and they are not installed in accordance with the instructions.
5 after I re-installed the operating system and the sound card driver, I have not experienced any fault for 10 consecutive hours since I started the system. Although the video card temperature remains the same
It is not caused by fan heat dissipation.

In addition, the following suggestions are provided for system usage:

Suggestion: Install all software under the D Drive Program Files
That is, change C to D in the C:/program files/*** step during installation.

cause:
1. make file management organized and always know where your software is installed
2. fully reserve disk C space, and there will never be issues that affect system operation efficiency due to insufficient disk C space
3. for some software that can run directly without installation, you can directly put the
shortcut on the desktop after the system is re-installed next time, the software becomes the legendary green software
4. in short, there are many benefits
