Adding things to DEP brings upon me a big eeeeew factor - especially if things used to work okay.
Consider adding SAS to your list of things you have done:
Download, install, update and do a full scan:
SUPERAntiSpyware: (SAS): http://www.superantispyware.com/
Look in the Event Viewer for clues around the time of the failure:
Here is a method to post the specific information about individual events.
To see the Event Viewer logs, click Start, Settings, Control Panel, Administrative Tools, Event Viewer.
A shortcut to Event Viewer is to click Start, Run and in the box enter:
Click OK to launch the Event Viewer.
The most interesting logs are usually the Application and System. Some logs may be almost or completely empty.
Not every event is a problem, some are informational messages that things are working okay and some are warnings.
No event should defy reasonable explanation.
Each event is sorted by Date and Time. Errors will have red Xs, Warnings will have yellow !s.
Information messages have white is. Not every Error or Warning event means there is a serious issue.
Some are excusable at startup time when Windows is booting. Try to find just the events at the date
and time around your problem.
If you double click an event, it will open a Properties windows with more information. On the right are
black up and down arrow buttons to scroll through the open events. The third button that looks like
two pages on top of each other is used to copy the event details to your Windows clipboard.
When you find an interesting event that occurred around the time of your issue, click the third button
under the up and down arrows to copy the details and then you can paste the details (right click, Paste
or CTRL-V) the detail text back here for analysis.
To get a fresh start on any Event Viewer log, you can choose to clear the log (backing up the log is offered),
then reproduce your issue, then look at just the events around the time of your issue.
