# pdflatex crashing with no error message and no output

I just switched to a new laptop, installed Miktex and Texmaker, and cannot get pdflatex to work. When started from inside Texmaker, the program runs for a few seconds, then spits out nothing. No error messages (or messages of any kind) in the log, no PDF, nothing. When run from the command line (using 'C:\Users\Name> pdflatex "D:\test.tex" ), I get a message that pdflatex is starting:

"Microsoft Windows [Version 6.1.7601]

C:\Users\Charlie Beer>pdflatex "D:\test.tex"
This is pdfTeX, Version 3.14159265-2.6-1.40.16 (MiKTeX 2.9 64-bit)
entering extended mode
(D:/test.tex
LaTeX2e <2015/10/01> patch level 2
Babel <3.9n> and hyphenation patterns for 69 languages loaded.

C:\Users\Charlie Beer> "


then it runs for a few seconds and I get an error that the program pdflatex has stopped responding and must be closed. The test file I'm using is a pretty basic document which builds just fine on both of the other computers to which I have access. Any help on getting this to run properly would be appreciated. Thanks.

UPDATE: When I simplify my file to use only basic packages, it builds:

\documentclass[12pt]{article}
\usepackage{amsmath}
\usepackage{amsfonts}

\title{A Stochastic Control Model for Energy Markets}
\author{Charles Beer}
\date{\today}
\begin{document}
\maketitle
\section{Abstract}
PLAIN TEXT
\end{document}


However, if I try to use extra packages, it seems that Miktex's package manager hangs and causes a crash:

\documentclass[12pt]{article}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{color,soul}
\usepackage[margin=1in]{geometry}

\title{A Stochastic Control Model for Energy Markets}
\author{Charles Beer}
\date{\today}
\begin{document}
\maketitle
\section{Abstract}
PLAIN TEXT
\end{document}

• This sounds very odd. Would you mind to share your text.tex with us? Maybe the culprit is in there. – Henri Menke Feb 2 '16 at 21:54
• Sorry, I'm not that familiar with posting here. I'm looking up how to post in a readable format and will get back to you. – Charles Beer Feb 2 '16 at 22:05
• Actually, you gave me the idea to simplify it even further (I had just pulled a page from an earlier document). If I use only basic packages, it does build. So, it appears that Miktex's package manager is not launching correctly to install new packages on the fly. Strange that I get no dialog box or error message, though. – Charles Beer Feb 2 '16 at 22:10
• Sorry about the continual updates. Every time I try to copy my test file, it shows up with no line breaks. If I post it in a new question, it appears fine. But, in comments here, it all squishes together. – Charles Beer Feb 2 '16 at 22:16
• check at first if your system is up-to-date. tex.stackexchange.com/a/108490/2388. If the problem persists make a bug report. – Ulrike Fischer Feb 2 '16 at 22:24
