Strange RunDLL, winlogon, and axaamon.dll errors

Specs (just in case):

Microstar? Mobo
2.66Ghz P4
64MB ATi Radeon 9000 Pro
512MB RAM
Windows XP

Problem:

When I log in (I start my computer, the user logins pop up, and I log in) things go fine if I leave my internet connection off. When I turn on my connection (un-standby my modem) and go into IE I get a set of errors.

"Run a DLL as an App"
-Asks to send error report, closable

"winlogon.exe - Application Error"
-CLick OK to terminate and restarts my computer, click debug to screw up my computer worse

"An exception occured blah blah axaamon.dll", UMonitor"
-Nothing happens when I close it


If I leave the error windows up, I can do whatever, but if I close them, my computer reboots. Any ideas how to fix this? I've tried system restoring because I was really desparate, but still gets the same error

[R.I.P.]

Doodage.....You say there's no problem until you enable your internet connection....Do you get the same result if you open your mail program instead of IE .
