My windo is shrunk on my screen it looks like a white line acrossed with 20 screens in a line I can't see to get in to gix it there is no mouse or anything how can I fix this it is windows 95 on an old laptop.

I'm afraid I don't completely understand your description. Could you please provide a screenshot so I can clearly see your problem?
Press the "Print Screen" button (might be spelled "prt sc") then post it as an attachment please.

However, someone may be able to help without seeing it, so even if you can't do that, someone may be able to help you.

Are you saying your main screen has collapsed so that all you get is a horizontal line on the screen? If so, that could be a hardware failure (or something else).
