Kernel Panic Reports are stored at:
/Library/Logs/DiagnosticReports
If you copy and paste that string into:
Finder > Go menu > Go to Folder
it will take you to where those reports are stored.
They are named with Date&Time and start or end in ‘panic’
If you find one, please post the entire report here, by using the “additional text” Icon in the reply footer (looks like a paper with writing).
Please don’t post more about 20 lines of any other types of reports — they are interminable, and any information useful for this purpose is on the first screenful.

If the above is just "word-salad" to you, just ask and Readers can explain a bit more.
