Phrase "It is going south on me"

Hi guys,

could you please explain to me this phrase? I know when something is "going south" it just means that it is loosing quality. But what does it mean when I add

My monitor is going south on me, for example?

= My monitor is crashing, because I didn't take care of it? / It's my fault that my monitor is crashing? / Or just, I have a monitor which is about to "die".

Other examples:

Although there aren't any other symptoms I'm wondering if it's not a battery going south on me.

I have never paid attention to this before. Is this normal or are my bearings going south on me?









Thanks a lot in advance for explanation.





Best Regards



Tomas
