Can you go Start - type eventvwr and press enter when it comes up.
This will open to Event Viewer and when it opens, ensure Event Viewer (Local) is highlighted in the left pane - if it isn't then just click on it.
When it has read the data and you are presented with Critical, Error etc. - click on Error and then on View All Instances of This Event in the lower right pane then look for time stamped errors for when the program locked up.
Clicking on any will produce more info in the pane below which you can copy & paste into your reply box by then clicking on Copy/Copy details as text in the lower right pane then right clicking in the reply box and selecting Paste.
