Troubleshooting Kindle Driver Error Whenever Connected to PC

[madame_newbie]

I had posted this before here regarding my kindle showing driver error whenever connected to Calibre on PC.

Since the five months I have ran and fixed this issue, somewhat, I have been running into driver error more and more frequently.

The fix that was advised and I used to fix the thing now serves more of a stopgap than actual permanent fix. Now it doesn't matter if I uninstalled and reinstalled calibre, eventually it would work fine for a while until I reconnect and the message will show again and attempt to fix the error - even during reboot - will work only for a bit before it starts again.

I'd like to know if anyone has ran into this problem before? And if so, have you found any permanent fix for it?

If not is this a sign I am stuck with a dying kindle and it's time to buy a new one?

I have an eye out for a slight older PW but am also kinda hoping that might be a permanent solution to this problem because Kindle is expensive in my country (due to Amazon not selling it officially here - have to buy via a third party that charges extra).

So, anyone? Thanks in advance.
