What makes me crazy, that if the USB stopped working, if I entered a USB Flash, it will work... and I have an external fan, it still runs normally!

Well that sort of points the finger at the USB plug, it's cable , or the KB itself you may have to work back from the plug Killer.

Now if you are ok with it you can test the connectivity of the plug and KB by undoing the KB and trying a multi meter resistance test between the plug and the KB end (connection). Do the same with the power connections and the data ones too.
See this for details
All common USB connectors

How did all the ports had the same issue, in the same time? I don't think it has to do with the pins in the USB itself.. I have got about 4 USB 2.0 and they all act the same, if it was one I would say maybe, but 4? :/

Well Killer there is only one thing left in my mind and that is thee drivers for that board for USB, chipset, VGA and the touchpad. The BIOS might even need updating though generally speaking I leave it to last and always back up before I do that BIOS updating. .

Worse case scenario - could be the board is going bad.

Try the drivers again and see.

The problem disappeared today, didn't even disconnect once... strange

Will update tomorrow if something happened, really strange. I haven't done anything at all.

Ok mate let sleeping dogs lie but don't be surprised if it pops up again as it sort of seems to be pointing at a connection or connections not being up to the job - loose or the solder has gone "dry" causing an intermittent contact.
