    PC Stuck on Static White Dash at Boot


    I'm experiencing a persistent boot issue on my custom-built PC built in 2016 that began around late November 2024. The system frequently gets stuck on a static white dash in the top-left corner of a black screen. I can’t access BIOS or Windows when this happens. Symptoms On boot, fans and LEDs power on, but nothing displays beyond a static white dash. Occasionally, the PC boots successfully and functions perfectly in Windows programming, gaming, editing, but this was back in Nov/Dec. CMOS reset sometimes restores functionality, but it doesn’t last. A new system speaker emits a single shor

    New SSD and when used for booting it boots on a black screen with a white dash.

    I bought a new SSD for my pc, i plugged it in and realized it was on MBR and i converted it into GPT using disk management. Everytime i go to bios settings i have to turn off secure boot and open CSM so i can see my SSD but everytime i use my ssd as a boot option it boots into a black screen with a white dash. Other tech savvies told me to unplug the power supply and hold the power button, well the black screen white dash thing is fixed but it just resets my bios options it turned on secure boot and disabled CSM and my boot option is on the HDD and the SSD is missing. I need help with fixing the black screen and setting up my boot settings for my SSD. Thank You For Hearing My Problem!
