Can't get table to correct width oder size

Question

I'm aware that here lots of questions regarding table formatting, but I couldn't fight the fitting answer and meanwhile I think it is any global misconfiguration.

My goal: fit table on page in textwidth, by NOT resizing the font to an unreadable size (what is happening if I some kind managed to fit the table on a page).

My approaches: tabular, tabularx, redefined columntypes, checking textwidth and linewidth (which are correct), resizebox

Settings:

\newgeometry{paper=a4paper,left=35mm,right=25mm,top=30mm,bottom=25mm} 

Latex Code

\begin{tabularx}{\textwidth}{l|l|X}
    {\bf Lore} & {\bf Ipsum} & {\bf Dolor} \\
    Lore & Ipsum & Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua. At vero eos et accusam et justo duo dolores et ea rebum.\\
\end{tabularx}

\resizebox{\textwidth}{!}{%
\begin{tabularx}{\textwidth}{l|l|X}
    {\bf Lore} & {\bf Ipsum} & {\bf Dolor} \\
    Lore & Ipsum & Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua. At vero eos et accusam et justo duo dolores et ea rebum.\\
\end{tabularx}}

\begin{tabular}{l|l|p{5cm}}
    {\bf Lore} & {\bf Ipsum} & {\bf Dolor} \\
    Lore & Ipsum & Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua. At vero eos et accusam et justo duo dolores et ea rebum.\\
\end{tabular}  

\resizebox{\textwidth}{!}{%
\begin{tabular}{lll}
    {\bf Lore} & {\bf Ipsum} & {\bf Dolor} \\
    Lore & Ipsum & Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua. At vero eos et accusam et justo duo dolores et ea rebum.\\                                            
\end{tabular}}

Output

In near future I have to deliver a thesis, please help me not having to switch to MS Word :-) Thanks.

Edit: The document class which I'm using: http://pastebin.com/y4ufWdu7

Edit2:

Great, I got it fixed. Now, that I was sure this must be an misbehaviour with my general configuration, I removed completely my documentclass: the table was in the expected position!

After step by step including back the packages, I figured out that the problem was caused by:

\usepackage{pdfsync}
\synctex=1

This is what you have to take into account, when you just use some template, which you don't really understand. I could have tried this debugging before, thanks for helping out a beginner.

This problem was also discussed in the answer of this post before.

Answer 1

Similarlly as said Christian Hupfer in his comment, I can not reproduces your result. Since you didnt provide any information about your preamble, I use make from your code the following MWE:

\documentclass[a4paper,pagesize]{scrartcl}
\usepackage[paper=a4paper,left=35mm,right=25mm,top=30mm,bottom=25mm] {geometry}

\usepackage{tabularx}
\usepackage{showframe}

    \begin{document}
\noindent
\begin{tabularx}{\textwidth}{l|l|X}
    \textbf{Lore} & \textbf{Ipsum} & \textbf{Dolor} \\
    Lore & Ipsum & Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua. At vero eos et accusam et justo duo dolores et ea rebum.\\
\end{tabularx}

\bigskip
\noindent
\begin{tabular}{l|l|p{5cm}}
    {\bf Lore} & {\bf Ipsum} & {\bf Dolor} \\
    Lore & Ipsum & Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua. At vero eos et accusam et justo duo dolores et ea rebum.\\
\end{tabular}
    \end{document}

In it I omit your experiments width resizebox and add showframe to show, that tabularx is perfect fit into page. Before table I also put \noindent that the table star at left border:
