Problem:
The Power button is working, CPU fan is working but there is absolutely no display on monitor. How to fix?
Resolution:
If the Power button and CPU fan are working but you are not getting any display on monitor then turn off PC.
- Check the power cable connecting to the monitor is tightly attached and in good condition. If the cable is okay then lets move to the next step of troubleshooting.
- Open the cabinet and carefully unplug RAM from the socket.
After unplugging clean the RAM.The gold contacts of RAM modules must be clean and free of debris in order to maintain a solid connection. To clean use a tissue paper.
- If cleaning doesn’t help then change the memory slot of RAM.
- If required change the RAM.
- Sometimes overheating may be an issue. In that case open the CPU, clean and put thermal paste. Attach the CPU fan.
