My computer crashed and after it rebooted I ran WhoCrashed and the program did not detect any dump files....

[Dutchoperative]

Not sure why it did not show my dump files or any of the information regarding my previous crashes.....

Depends on how it crashed, did you get the message that it was preparing the file to read?

You said you have issues like this before, did is start after you installed or removed something if you can remember?
