Try the free WhoCrashed program, which is friendlier than the Windows MiniDump reader and may reveal the reason for the crash. Download it from here http://www.resplendence.com/whocrashed and install it.
To run it click Analyze, then scroll down to see the error(s). When it is first run, it will download the Windows Debugging package, which is perfectly normal. All minidumps found on the system will be listed. Copy & Paste the message(s) back here if you don’t fully understand it/them.
