I have been getting a white ez debug cpu light on my mobo. No display is showing up. I feel like I should invest in a new PSU, but at the same time the rest of the pc functions, including fans of the GPU, case, and AIO, with the exception of the case light that indicates whether the pc is on or not. I have tried diagnosing by removing one stick of ram, disconnecting and removing GPU, and disconnecting HDD. Nothing seems to be working and I still get the white ez debug light for the CPU. This CPU and system has worked for 2 years since 2019 and this light came on in the summer of 2021, ruining my gaming adventures. I am very skeptical on whether this is a CPU problem or this PSU is the problem. I also don't know whether I would need a post card to diagnose further.
