  Normal mode - Wikipedia, the free encyclopedia
Normal modes in an oscillating system are special solutions where all the parts of the system are oscillating with the same frequency (called normal frequencies or allowed frequencies).
The concept of normal modes is of vital importance in wave theory, optics and quantum mechanics.
The allowed frequencies are dependent on the normal modes, as well on physical constants of the problem (density, tension, pressure, etc.) which sets the phase velocity of the wave.

 Concept of Normal Modes
In general a normal mode is defined by: a solution for the motion of the system in which all state variables move with simple harmonic motion (i.e sin or cos), and all at the same frequency (called the mode frequency):
Having seen this example, the definition for normal modes we gave at the top may make more sense: A normal mode is a solution for the motion of a system in which all state variables "move" with simple harmonic motion (i.e sin and cos), and all at the same frequency (called the mode frequency):
The mode frequencies and the mode amplitudes are the eigenvalues and eigenvectors of the eigenvalue problem associated with the system, respectively.

When reading modes, all selected modes (from mode-spec) of the modes in the normal mode file will be read (assuming there is enough space).
The resulting modes are the quasiharmonic modes of the system, and should roughly match those from a strightforward normal mode calculation.
This command will add on the defined mode to the end of the normal mode vector, unless the destination is specified with TO n in which case it will be placed as mode number n.

 CONGEN - Vibrational Analysis
When reading modes, all of the modes in the normal mode file will be read (assuming there is enough space).
A contiguous subset of modes may be specified (the default is all modes), and an appropriate magnitude may be specified (see section Normal Modes).
The modes for all specified modes may be written out in one file, or in separate files for different modes where sequential unit numbers are used starting with the specified unit number.

 Coupled Oscillation Simulation
There are two sets of terms; on top are the magnitude terms, which shows the amplitude of each normal mode, and on the bottom are the phase terms.
If you move the mouse over one of the modes, it will turn yellow, and the motion of the corresponding mode will be drawn underneath the line of oscillators in yellow (unless it's too small to see).
This is because the two active modes have frequencies that are very close, causing beats to occur.

every normal mode of the pipe has pressure antinodes at x = 0 and x = L and, for the nth normal mode, the number of pressure nodes within the pipe is equal to n.
Normal modes for which all three indices are non-zero have pressure antinodes only at isolated points.
For the 1,1,0 mode the pressure antinodes are four vertical lines at the corners of the floor and ceiling, and for the 2,1,0 mode there are two additional such lines midway the long walls.

 XP - safe mode b4 normal boot - TechSpot Troubleshooting
To understand what it means I have tried to get information about the precise differences between the safe mode and the normal mode but I didn't get very far.
As far as this particular problem goes (normal mode starts okay after a safe mode session, but not after another normal mode session), my guess is that it's related to a regular software program, possibly one of the startup programs.
So, if you can start in normal mode after safe mode, that says that there is nothing inherently wrong with the STARTUP procedure.
