Navigating Through the Flash: A Guide to Resolving Monitor Glitches


I’m encountering an issue where my monitor displays intermittent white flashes upon starting my computer. Despite attempts to reboot, change DisplayPort cables, and even endure prolonged shutdown durations, the problem remains unresolved. Unfortunately, I haven’t been able to replace any hardware components yet. The system also fails to progress beyond the desktop due to these flashes, preventing any attempt to update or modify display drivers. While I have captured this anomaly on video, I’m unable to share it here.

Could you provide any insights into this matter? My setup includes an i7 8700k processor, Gigabyte 2070 graphics card, Asus Prime motherboard, 32GB RAM, and an 850W EVGA PSU.”

I hope this rephrasing meets your needs and conveys the issue clearly to an expert. If you need further assistance, feel free to ask!


Intermittent white flashes on a monitor are not just disruptive; they can be indicative of underlying hardware or software issues. When standard troubleshooting steps like rebooting, changing cables, and attempting driver updates fail, it’s time to delve deeper into potential causes and solutions.

Potential Causes


Hardware Connectivity

  • Check Connections

    : Ensure all cables are securely connected. Loose connections can cause intermittent display issues.

  • Reseat Components

    : Carefully reseat the graphics card and RAM to ensure proper contact.

  • 2.

    Graphics Card

  • Test the GPU

    : If possible, test your Gigabyte 2070 in another system or try a different GPU in your current setup.

  • 3.


  • Alternate Monitor

    : Connect to a different monitor to determine if the issue is with the display itself.

  • 4.

    Drivers and Software
