Step 1: Check Monitor and Cable Connections
Ensure your monitor is powered on and the power cable is securely connected.
Check that the video cable (HDMI, DisplayPort, etc.) is firmly connected to both the monitor and PC.
Confirm that the video cable is connected to the GPU's video connection, not the motherboard's video connection.
Try a different video cable or monitor input port.
If possible, test your monitor with another computer or test your PC with a different monitor.
Step 2: Verify the Display Source
Most monitors have multiple input sources. Use the monitor’s buttons or on-screen menu to:
Select the correct input source (e.g., HDMI 1, DisplayPort).
Switch between inputs if unsure.
Step 3: Look and Listen for PC Activity
Check for spinning fans, motherboard RGB lights, and storage drive activity.
Listen for any beep codes from the motherboard (if it has a speaker attached).
If your motherboard has a debug LED or Q-code display, refer to the manual to interpret the code.
Step 4: Check Your Graphics Card
Power off and unplug the PC.
Remove and reseat the graphics card to ensure it's fully inserted into the PCIe slot.
Verify the card is connected to the power supply (typically one or two 6/8-pin connectors).
If your CPU has integrated graphics, try removing the GPU and plugging your monitor into the motherboard’s video output instead.
Note: AMD Ryzen CPUs without a “G” (e.g., 5600X) and Intel CPUs with an “F” (e.g., i5-12400F) do not have integrated graphics.
Step 5: Verify Power Supply Connections
Ensure the 24-pin motherboard power and 8-pin CPU power cables are securely plugged in.
Confirm that the GPU power cables are also connected (if required).
If available, test with a known-good power supply.
Step 6: Check RAM
Power down and reseat the RAM sticks.
Try booting with one stick of RAM at a time, testing each slot individually.
Faulty or improperly seated memory can prevent the system from completing POST (Power-On Self-Test).
Step 7: Reset CMOS
A CMOS reset can clear potential BIOS misconfigurations:
Power off the system and unplug it.
Locate the CMOS battery on the motherboard (a small silver coin cell).
Remove it for 30 seconds, then reinstall.
Alternatively, use the CMOS jumper/reset button if available (refer to your motherboard manual).
Common Problem Indicators
Symptom | Likely Cause |
No fans or lights | PSU or motherboard issue |
Fans spin, no display or beeps | RAM, CPU, or motherboard |
Beep codes heard | Refer to motherboard manual |
Monitor says “No Signal” | GPU, cable, or monitor issue |
Debug LED stuck on “VGA” or “BOOT” | GPU or boot device issue |
✅ Final Steps
If the system boots successfully after these steps:
Reconnect components one at a time to identify the faulty part (if any).
Update BIOS and drivers to the latest versions.
Monitor system behaviour to ensure long-term stability.
