DD has done something to my screen and it's driving me mad

[Hayls]

Ddw as messing about on PC earlier and has made everything very weird. There's a black outline round the whole screen and everything is supersize. Icons on desktop seem to be normal size but the task bar has shrunk because everything is so big- when I log off the sign on icons are huuuge. ON this page the text box takes up the whole screen whereas normally I can see everything. I've been trying to fox for ages to no avail, any help would be gratefully received!

She's changed the resolutions, to change back right click on the desktop, go to properties and go to settings tab. You can change it in there prob to 1024x768
