Hi rennc10,
a) Do you recall making any changes to the computer before this happened?
b) Does this happen only with specific file types?
I would suggest you to try the following steps:
Step 1: Let’s first go through the event viewer logs and check what is the application and module that is failing to load.
Open event viewer
http://windows.microsoft.com/en-US/windows-vista/Open-Event-Viewer
What information appears in event logs? (Event Viewer)

Step 2: Put the computer in clean boot and test
Follow Step 1 in the link below,
How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7

If everything works fine after a clean boot, you can infer that some third party services are causing the problem.
Important: - Remember to put the computer back to normal startup follow step 7 in the link.
What is your operating system default input language? The following article addresses similar issue- Input Method Editor (IME)
