"svchost.exe - Application Error"

[Guest]

I am running xp sp2. This morning when I started the computer a pop up "Data
Execution Prevention - Microsoft Windows" came up saying "To help protect
your computer, Windows has closed this program" referencing "Generic Host
Process for Win32 Services". Then a second pop up "svchost.ext - Application
Error" came up saying "The instruction at 0x7e030af2 referenced memory at
0x7e030af2. The memory could not be written.". I clicked the "ok" button of
the second pop up to close it, after which the windows tool bar on the bottom
of the screen stops functioning. I closed Outlook which autostarted, but it
still shows on the windows tool bar. The start button on the tool bar would
not respond. I opened task manager and click restart, and that is when
everything froze. I had to do a hard shut down by holding down the power
on/of button. When I booted up the computer again, the "Data Execution
Prevention" pop up came up again, but not the "svchost.exe - Application
Error".

Anyone has any clue as to what happened, and anything I can do to fix?

Thank you.

Can you do anything at all when you log on normally? Can you log on to
Safe Mode? Is your machine free of virus and other pests? The DEP
settings can be modified:

The settings can be changed in the /noexecute= switch in the boot.ini file:

Did not try to log onto save mode. After the hard shut down and reboot, only
the DEP pop up showed up and not the svchost error. Then when I closed the
DEP pop up, I was able to continue on as normal.

During the initial boot when I got the svchost.exe application error pop up,
after I clicked the ok button to close that pop up, I was able to navigate to
other running applications only by alt-tab and not via the windows tool bar.
Even the start button on the windows tool bar would not respond.

Make absolutely sure that you have no virus and pests on your computer
and if the error persists use the /noexecute=OptIn switch in the
boot.ini file.
