Black screen after power on (GPU/RAM issue)

What is No Display?

The No Display error is categorized as a high-severity graphics card (GPU) and motherboard issue that can significantly impact your PC's stability. Upon pressing the power button, the computer fans spin and LEDs light up, but no video output is sent to the monitor. When experiencing the Black screen after power on (GPU/RAM issue) fault, users often report sudden system crashes, unresponsive behavior, or a blue screen of death (BSOD). In most diagnostic scenarios, this problem is directly triggered by underlying hardware or software complications such as RAM module not fully seated or dirty contacts, incorrect monitor input source or faulty video cable (HDMI/DP) and GPU not fully seated or missing PCIe power connectors. To permanently resolve the No Display issue and prevent further system degradation, it is highly recommended to follow our step-by-step troubleshooting guide below, ensuring your graphics card (GPU) components are functioning correctly.

Common Causes

• RAM module not fully seated or dirty contacts
• Incorrect monitor input source or faulty video cable (HDMI/DP)
• GPU not fully seated or missing PCIe power connectors

Step-by-Step Fix Guide

• 1
  Check video cable and monitor input source channel

  Applying the first fix (Check video cable and monitor input source channel) addresses the most common root cause of No Display and restores baseline functionality.

• 2
  Reseat RAM modules in slots A2/B2 firmly

  If the problem persists, proceeding with the remaining steps ensures all edge cases related to gpu instability are covered.

• 3
  Reseat GPU in the PCIe slot and verify power cables
