Question PC displaying a black screen with an underscore
Hey, I'm trying to figure out my issue. I've been trying to enter BIOS mode several times, but once I do, the screen shows a white underscore on a black background. Before I power off the PC, I turned on Safe-Boot in case it would help start the BIOS. I'm not sure what to do next. I also removed the graphics card because the motherboard lights up white, and I took out my SSD to try booting from a Linux USB drive. Thanks in advance for your help.
Hello, thank you for your reply. Your PSU is from Bequiet with 500W capacity and should still function. The main disk is an Nmve SSD from WB with around 80 GB remaining. I attempted to connect it on my primary monitor, but it didn't work there—only a black screen appeared on the secondary monitor. I also tried resetting by removing the CMOS battery, but that didn't resolve the issue. If you need further details, please let me know.
Restore BIOS configurations to their standard settings.
Simply removing the battery isn't sufficient. A small amount of remaining charge remains in the PSU capacitors.
Unplug the PC from power, detach the battery, and hold the power button for a few seconds to fully discharge the PSU capacitors.
Alternatively, you can connect the battery contact pads on the motherboard for extra assurance.
For additional certainty, short the BIOS reset pins on the motherboard as well.
