Wow you are getting alot of crashes have a look at the last bit of part 2 now most of the crashes are in the AMD video drivers and the AMD Fuel Service , it also appears firefox and other programs have been crashing.
In the first instance try this
Click the AMD Catalyst Install Manager to highlight it.
Above you will see a button that says 'Change'. Click that.
Now Click Uninstall Manager, Click Next
Then Click on custom and press Next again.
Tick the box for AMD APP SDK Runtime, then click Next
Now Click Finish.
The issue should be resolved if it isn't can you download a new copy of the AMD video drivers and then uninstall your current ones and then re-install. Your problem appears to lay with the AMD drivers
