Industrial PC beeps and No Display

The industrial computer plays an important role in the production process, but sometimes after the machine is turned on, the alarm sounds, but there is no display on the monitor. This problem may cause the industrial computer to fail to operate normally, and then affect the normal production. This article will introduce three solutions to help you troubleshoot and resolve this issue.

Method 1: Open the case cover to check whether the memory module is installed or loose;

First, we need to check whether the memory module is installed or loose. Open the case cover and check whether the memory module is installed securely. If the memory module is not installed correctly or loose, we need to re-insert the memory module into the slot and make sure it is firm.

Method 2: Is the alarm sound the same after the memory module is unplugged and turned on?

If the memory module has been correctly inserted into the slot, but the alarm sounds after booting, but there is no display on the monitor, then we need to conduct a deeper investigation. We can try to unplug the memory stick, and then turn it on again. If the beep goes away or the sound changes at this point, the problem is most likely memory. We can try to replace the memory module, and then turn on the computer again.

Method 3: Clear CMOS (maybe wrong settings) or replace BIOS;

If none of the above two methods solve the problem, then we need to try to clear the CMOS or replace the BIOS. First of all, we can try to clear the CMOS, because sometimes there may be problems with the CMOS settings, which will cause the industrial computer to fail to start normally. We can clear CMOS by moving the CMOS clear jumper or unplugging the CMOS battery. If the problem still exists after clearing CMOS, then we need to consider replacing the BIOS chip or replacing the motherboard.

Summarize:

To sum up, the alarm sounds after the industrial computer is turned on, but there is no display on the monitor. The problem may be caused by improper installation of the memory module, memory failure, CMOS setting problem or BIOS chip damage. We can troubleshoot these problems in turn and take corresponding measures to solve the problem. If you still can't solve the problem, please contact professional maintenance personnel to deal with it.
