When it's cold, the computer won't turn on the monitor.

The reasons why the computer's startup monitor does not light up in cold weather are as follows:

1, low temperature will affect the performance of electrolytic capacitor, which makes it difficult to start some power supplies. This is probably the reason described, and there is no particularly good solution.

2. It may be that the lubricating oil of CPU fan has solidified. Or like a server, the temperature difference is more than 20 degrees.

3. It may be that the monitor is not turned on. Check whether the power switch and power adapter of the monitor are turned on.

4. The cable may be loose. Check whether the video interface between the monitor and the host is connected correctly.

5. It may be that the host graphics card is loose, resulting in no screen display. Try to disassemble the computer and fix the graphics card again;

6. It is also possible that the monitor itself is out of order and needs further maintenance after sale.
