Help me. Warning message after runnning model , not analysing - ETABS 17

[HoangHuynh]

Hello everyone , I need help. After running the Model , I checked the log and it showed that :
* * * W A R N I N G * * *
THE STRUCTURE IS UNSTABLE OR ILL-CONDITIONED !!
CHECK THE STRUCTURE CAREFULLY FOR:
- INADEQUATE SUPPORT CONDITIONS, OR
- ONE OR MORE INTERNAL MECHANISMS, OR
- ZERO OR NEGATIVE STIFFNESS PROPERTIES, OR
- EXTREMELY LARGE STIFFNESS PROPERTIES, OR
- BUCKLING DUE TO P-DELTA OR GEOMETRIC NONLINEARITY, OR
- A FREQUENCY SHIFT (IF ANY) ONTO A NATURAL FREQUENCY

TO OBTAIN FURTHER INFORMATION:
- USE THE STANDARD SOLVER, OR
- RUN AN EIGEN ANALYSIS USING AUTO FREQUENCY SHIFTING (WITH
ADDITIONAL MASS IF NEEDED) AND INVESTIGATE THE MODE SHAPES


---------------------------------
BASIC STABILITY CHECK FOR LINEAR LOAD CASES:
NUMBER OF NEGATIVE STIFFNESS EIGENVALUES SHOULD BE ZERO FOR STABILITY.
(NOTE: FURTHER CHECKS SHOULD BE CONSIDERED AS DEEMED NECESSARY,
SUCH AS REVIEWING EIGEN MODES FOR MECHANISMS AND RIGID-BODY MOTION)

NUMBER OF NEGATIVE EIGENVALUES = 4981
Certainly it didn't analyse. I 've already checked model , assigned restraints.
Please help me . I'm doing graduated thesis

my tutor teacher ran that file in his computer and its fine . I ran it again and the problem still there . If my computer has problem so why another model shows fine result .

There's a lookdown in my state and I'm bored enough at home that I would have checked your model if I had Etabs at my home computer.
So I really can't help you in this regard.

Hello . I tried to not meshing WaLL and the Model showed Period , Ux, Uy , Rz .
Was the result reliable ? We usually mesh Wall and Run and analyse mode shape
