Computer Specs
XP professional 2002 Service Pack 3
2.53GHz 3GB Ram

Upon boot up before windows logo appears I get:

dialog box that says:

Logonui.exe - Application Error

The instruction "0x01419de9" referenced memory at "0x0109822C" the memory could not be "read"


Click OK to terminate program OR Click cancel to debug program

Then I have to click a total of 10x before a logon box for windows comes up and I click OK and windows boots up. Once the desktop is visible its about 5-15 seconds before another error message appears

dialog box that says:

Windows logon UI encountered a problem and needed to close

Does this happen if you boot into safe mode?

Let's try this.

Download/install BlueScreenView, http://www.nirsoft.net/utils/blue_screen_view.html.

Double-click BlueScreenView.exe file.

When scanning is done, Edit/Select All...then File/Save Selected Items.

Save the report as BSOD.txt.

Open BSOD.txt in Notepad, copy all content and paste it into your next reply.
