Steps to judge whether the graphics card is good or bad
After installing a new graphics card, the monitor does not light up
motherboard
1. Different motherboards have requirements for the installation positions of different numbers of memory sticks. Different numbers of memory sticks should be installed according to the positions specified by the motherboard, especially the server motherboard, otherwise the system may not start up (see the motherboard manual or official website PDF for details). Most of the main boards are 2 and 4 slots to insert two to form a dual channel;
2. For some server motherboards, when reinstalling the system, you need to plug the VGA cable into the motherboard interface. After installing the system and installing the driver, the screen can be displayed on the new graphics card;
CPU
1. When the CPU temperature is found to be too high, a reference idea is to check the power supply pins of the CPU cooling fan. If there are only three, the lack of temperature control pins may be the cause of the high temperature of the CPU under this fan. (Generally four pins, the fourth is the temperature control pin)
2. When investigating the CPU radiator, pay attention to the height limit of the chassis for the radiator;
Memory
1. Win7 Professional Edition system, the memory limit is 192G
graphics card
1. The display does not display, one of the possible reasons is that the graphics card interface is broken, try another port (if not, try changing the data cable);
2. The monitor frequently blacks out, it may be that the power supply cable of the graphics card is loose;
3. When investigating the graphics card, pay attention to the height and length limit of the graphics card of the chassis;
Steps to judge whether the graphics card is good or bad
1) Plug in and turn on the power to see if the graphics card rotates. If it turns on, the power supply of the graphics card is no problem. Check whether the display is blurred or unstable. Also consider factors such as loose memory sticks and dust. You can try to plug and unplug the memory stick and remove the dust. .
2) In the system, you can do this: right-click My Computer Properties—Device Manager—Display Adapter—double-click the graphics card—see device status.
After installing a new graphics card, the monitor does not light up
1) If there are multiple screens, one will light up, install the driver first;
2) For single screen, check if the connection port is loose; change HDMI, VGA, DP to test separately
power supply
1. During the use of the host, the CPU fan frequently starts and stops, and the power indicator of the monitor flashes, but the monitor does not light up. Turn off the power switch of the host, tighten the power supply cable of the main board, and the position of the power plug;
other
1. The recorder has no display problem, which may be due to poor contact of the data cable, reinsert the data cable and power supply cable;
2. Some server motherboards and CPUs cannot install the winserver system normally, and BIOS settings may be required. The method is generally available on the official website of the motherboard and CPU.
Internet problem
1. If there is a problem with the network, first check whether there is a problem with the computer network used by the person reporting the error, such as IP settings, IP conflicts, whether other computers can be pinged, etc., and then check whether the network port on the motherboard is plugged in properly. Principle exclusion.
