Is there a green button labeled start at the bottom left at your screen? If yes, then you're running windows.
Now, the problem of yours might be related to not having drivers for your graphics card installed and therefore you might be using old microsoft ones. Now you need to find out which graphics card do you have. You could check this in the pc manual or could try this:
press start button, then select run command and type dxdiag there. Press enter, wait a minute until it finishes, select display tab and paste here what you see in display: line.
