One broken thing I can find in my sleep. But this machine has two or three faults tangled together, and every time I fix one the symptoms shift and point somewhere new. I have been chasing it for hours, going in circles, and I am starting to doubt whether I know what I am doing at all.
More people experience this than they realize.
You can fix a single fault, but tangled multi-fault problems send you in circles.
If this sounds familiar, the Library can help you find the bigger picture.
