You are allowed to use line spacing to make things a little easier to read.
Looking at you last post It would appear that you were trying to supply the USB port with less voltage than it expects.
This in and of itself could cause various issues ranging from intermittent uploads to erroneous readings from external sensors to the board simply not working.
The board expects a reasonably consistent supply voltage from the USB port for the circuitry to work properly.
Such large variations (although you might consider them large) will give issues.
