🖥️Black Screen on Startup (No BIOS Logo)
Encountering a black screen on startup with no BIOS logo can be alarming. This issue often indicates hardware or firmware problems. In this guide, we'll walk you through the steps to diagnose and resolve this problem.
🔌1. Check Power Supply and Connections
Ensure that your computer is receiving power:
- Verify that the power cable is securely connected.
- Check if the power outlet is functioning by plugging in another device.
- Look for any LED indicators on the motherboard or case fans spinning.
💾2. Reseat RAM and Other Components
Loose hardware components can prevent your computer from booting:

🧪4. Test with Minimal Hardware
Reduce the system to essential components to identify faulty hardware:
- Disconnect all peripherals and remove non-essential hardware.
- Attempt to boot with only the motherboard, CPU, one RAM stick, and power supply.
- If the system boots, gradually add components back to identify the faulty one.
🛠️5. Check for Beep Codes
Beep codes can indicate specific hardware issues:
