My computer turns on normally and the fans/lights are working, but there’s no display on the monitor. The screen stays black and I’m not getting any signal or boot screen. I already checked the monitor cable once but still facing the same issue. What could be causing this and how can I fix it?
Your PC is getting power, but the display issue is usually caused by loose RAM, graphics card problems, or a bad monitor connection.
Try these quick fixes:
1. Check the monitor cable and try another HDMI/DP cable.
2. Restart the PC after unplugging power for 2–3 minutes.
3. Remove and reseat the RAM properly.
4. If using a graphics card, reconnect it or try the motherboard display port.
5. Disconnect extra USB devices and restart.
6. Test the monitor with another device if possible.
If the screen is still black, the issue may be related to the RAM, GPU, motherboard, or power supply.
