About the TDSS issue, no there is no place else to look. We recently had a new variant popup that we were having a hard time getting rid of (Probably what you read about in Kevin's thread) but the tools have been updated to deal with it. TDSSKiller does a fantastic job of getting rid of it. If it came back, you would start having problems with the OS or with your browser searches. You have rebooted enough times to allow TDSS to come back if it was still there.
Now regarding the event viewer logs, starting on the 13th all of your problems have seem to gone away. This is a good thing, except we are troubleshooting a problem, which makes it a bad thing. So we go at this a bit differently.
I need you to reboot windows cleanly. To do that please go to the run command and type in msconfig . Once that starts, select selective startup, and then uncheck the load startup items. Now click on the services tab, and down near the bottom of the window, check the box that says Hide all Microsoft Services now go up and uncheck all the services still listed, make sure you scroll down the list if need to unselect all the non Microsoft services. Now click apply, then click OK and reboot the computer.
Now reboot the computer again, and see if the computer has that ending program again. If not run msconfig again and recheck all the services and then click apply and then ok and reboot again. Then once the computer has started, reboot again and see if the ending program comes back. If it doesn't then run msconfig again and unselect the non Microsoft services again, and check all the startup items. Then click apply and OK and reboot. Then once the computer is running again, reboot it and see if you get the end program again. Now run msconfig and select normal startup then click apply then OK and reboot.
Let me know when the end programs appeared in the above procedure. I know it is long and involves a lot of rebooting, but that is the only way to track down the problem.
