Herman, I doubt it but go into your Windows/System32 or WINNT/System32 folder and find clipbrd.exe which is the Windows XP clipboard and double click it to open it and see by chance if the contents are still on the clipboard if you copied then pasted to notepad.
If the PC had crashed or lost power then perhaps there may have been a chance to recover something from a temp file but if you simply closed Notepad without saving, whatever you had written is history.
