Screenshot Complications?

i knew all that, however i dont know where to find the "clipboard". where is it????

The clipboard is where stuff that's copied via Ctrl-C is stored temporarily.
To retrieve it, press Ctrl-V (or select "Paste" in you image editing software), and the screenshot should appear in it.

In some versions of Windows there are clipboard viewers available, but they wouldn't help you much with binary content (like an image) anyway, so just paste whatever is in your clipboard, and you should be able to get those screenshots.
