It started as a black screen /mouse cursor only issue. no desktop whatsoever. couldn't run explorer.exe thru task manager. got into device manager thru cmd, but after removing the nvidia and windows graphics drivers, no change. i've run lenovo diagnostics that show NO issues. Then I reset o/s saving files. same results. The only thing I haven't done is start with a freshly partitioned hard drive and install o/s from there.

Wouldn't the lenovo diagnostics show the GPU is failing?
