What do you mean by your computer "knocks up"? How do you "change screens"?
You need to provide clear description of the symptoms, else I doubt anyone will be able to provide help.
So, with the little information you provided I'm guessing you have a display problem. The issue may be Mutter, the composite part feature of your X server, which is a bit#h (pun intended: 'Mutter' in German means "Mother"

).
To disable Mutter (a.k.a., fall back to non-composite mode) you need to do the following:
1. Open 'System Settings'. Click in sequence:
'Activities' (upper-left corner)
'Applications'
'System Tools'
'System Settings'
2. Click on System Info' (last row of icons)
3. Click on 'Graphics'
4. Click on 'Forced Fallback Mode' (it's grayed out when OFF, but turns when ON)
5. Press Ctrl+Alt+Backspace keys on your keyboard - this restarts the X server.
Hopefully your problem
is the composite mode.
Mutter (the composite option of your X server) is notorious for being a piece of cr.p!
