DEP blocking explorer.exe at boot sometimes?

[Noozer]

I've just started having a problem with my system at startup.

The blank desktop comes up, then I get my task bar, then DEP pops open a
warning telling me that it is blocking explorer.exe!

This sounds like spyware/malware/virus but the machine comes up clean.

I also have several faulting traps in my Application Event log for explorer.
They look like this:

Hi Steve,
All Posts about DEP and answers here:

If you have a third party shell running in the background can cause this
error to occur and an BHO on your Browser so with Process Explorer you will
see which is causing this error.

1- Click start >> Control Panel >> Double Click Network and Internet
Connections >> Double click Internet Options, on the IE Properties window
you will see these Options:
General | Security | Privacy | Content | Connections | Programs
| Advanced .
Click on Programs tab then click Manage Add-Ins and Disable all non-Verified
Add-Ins there and Reboot your machine and try to open the Windows explorer
(you need to Renable the Add-Ins One-by-One later and see the culprit which
will cause the Error and Remove it or leave it disabled).

Try to Turn the DEP OFF by doing this:
Right click My Computer and select properties, then on the System properties
click on Advanced Tab.
Then click on StartUp and Recovery Button, on the StartUp and Recovery
window click on Edit Button under System Startup and edit like this:

multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP
Professional" /fastdetect /NoExecute=AlwaysOff.

Then click On Performance Button under Advanced tab, on Performance Options
click on Data Execution Prevention Tab and check this Radio Button:
(*) Turn on DEP for essential windows programs and services only.
HTH.
