Why is my computer screen just turning white on startup?
I’m experiencing a frustrating issue with my computer where, upon starting it up, the screen turns completely white. This occurs right after I press the power button and before any other loading screens appear. It seems like the system isn’t able to proceed beyond this white screen phase. I haven’t installed any new software or made any hardware changes recently that might explain this sudden behavior. The white screen appears consistently each time I try to boot up my computer, making it utterly unusable. There are no error messages, and I can’t access the desktop or any of my files. What might be causing this problem and why is my computer screen just turning white on startup?

If your computer screen turns white on startup, it might indicate a problem with the display driver or the operating system. Here are a few steps you can try to troubleshoot the issue:
- Safe Mode: Boot your computer into Safe Mode. To do this, restart your computer and press the F8 key (or the key designated by your computer’s manufacturer) to access advanced boot options. Select Safe Mode. If your computer boots up successfully in Safe Mode, then a corrupted display driver may be at fault. Try updating the display driver or roll back to a previous version.
- Check Connections: Ensure all cables connecting your monitor to your computer are secure and undamaged. Sometimes a loose or damaged cable can cause display issues.
- External Monitor: Connect your computer to an external monitor. If the external monitor displays correctly, the issue might be with your primary monitor.
Your situation where the computer screen just turns white on startup can be highly frustrating. This could be due to a malfunctioning hardware component or software corruption. Here are a few things to investigate:
1. Hardware Issues: Check if there are any loose connections or hardware that might need reseating. Components like RAM or the graphics card should be properly seated.
2. Display Issues: The issue could also be with the display itself. If possible, connect your computer to a different monitor or use an HDMI/DisplayPort cable to rule out monitor issues.
When my computer had the same problem as you’re describing — turning white on startup — it was due to a corrupted BIOS/UEFI setting. Here’s what I did:
1. I entered the BIOS/UEFI menu by pressing the designated key (like F2, DEL, or ESC) on startup.
2. Once in the BIOS, I restored the settings to default. A corrupted setting was causing my issue, and this reset brought my computer back to life.
3. If you’re not comfortable doing this, look up your specific motherboard’s instructions to avoid any missteps.
One common reason for your computer screen just turning white on startup could be a GPU (graphics processing unit) issue. The GPU might be malfunctioning or not properly seated in its slot. If you’re comfortable with opening up your computer, you can try to reseat the GPU. Ensure the computer is off and unplugged, then carefully take out the GPU and place it back into the PCIe slot. If reseating doesn’t work, you might need to test with a different GPU.
A lesser-known reason for a white screen on startup could be a failing power supply unit (PSU). The PSU is critical for consistent power delivery, and any inconsistencies can cause bizarre behavior in the system, including a white screen on boot. If other hardware seems to be functioning correctly, and you’ve ruled out software issues, it might be worth testing with a different PSU to see if that resolves the problem.
