First, ensure your monitor is functioning correctly. Disconnect it from the computer and power it on and off. If it displays any information, your monitor is likely working fine.

If you hear beeps from your computer, these could indicate specific problems. Refer to your motherboard’s manual for beep code meanings.

Resetting the BIOS memory will revert settings to factory defaults. You can do this by removing and reinserting the CMOS battery on the motherboard.
5. Check Power Supply Voltage
Ensure the power supply voltage switch is correctly set. An incorrect setting can prevent the screen from displaying properly.

Remove and reseat all data and power cables, RAM, video card, processor, etc., inside the computer. This can resolve a variety of issues.
7. Test the Power Supply
If the computer’s lights are on and fans are running, but there’s no display, the power supply might be at fault. Test the power supply and replace it if necessary.
8. Start with Essential Hardware Only
Boot the computer with only essential hardware to pinpoint problematic components. Remove non-essential peripherals like speakers, keyboard, mouse, and USB devices.
9. Update Video Card Drivers
Outdated or corrupt video card drivers can cause display issues. Ensure your drivers are up-to-date and install the latest version.
10. Test Using Spare Parts
Using known working spare parts, replace each hardware component one at a time to identify the faulty component.
If these physical solutions don’t resolve the issue, consider software-based fixes:
- Safe Mode Startup: Booting in safe mode can help identify problematic drivers or software, as it loads only essential drivers.
- System Restore: Rolling back to a previous system version that functioned correctly may help resolve the issue.
- Check for Software Updates: Sometimes, system updates can cause issues. Ensure your system is up-to-date with the latest patches.
