windows xp sp3

Everytime i press ctrl alt del to logon to the system, notepad pops open with some random error message filled with a bunch of gibberish i can't read, just a bunch of squares and stuff. Once in a while it says "c:\windows\system32\mui\0407\xpsp1res.dll" the solutions i've found where to delete the desktop.ini files in startup and a few other places, which i did, but now the error message just changes folder to \408\xpsp3res.dll

This being an error before i even get to login, how would i go about finding out whats running on bootup? I don't see anything out of place in msconfig or any weird services. Hijack this isn't helping either.

Can you post a picture of the problem? – bwDraco Apr 18 '11 at 18:37
Maybe tomorrow, can you even take a screenshot at the ctrl alt del screen? – acme64 Apr 19 '11 at 17:07
If you can't take a screenshot in software, try using a camera to take a picture of the screen. The quality will be lower, but at least we can see what the problem is. – bwDraco Apr 19 '11 at 17:12
sorry for the delay, here we go: – acme64 Apr 21 '11 at 14:00
These are dialog boxes normally used to display notifications to users before logging in, as on a school or work computer. The files you mentioned, xpsp1res.dll and xpsp3res.dll, are related to service packs. It looks like you have some kind of problem with a system file. Perhaps you have a problem with the SP3 update or its files? – bwDraco Apr 21 '11 at 14:35

I found a suitable solution to the problem, never found the cause though.

creating this key disables the popups: Root Key: HKEY_LOCAL_MACHINE Key: SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Winlogon Entry: NoPopupsOnBoot Data Type: REG_SZ

found the info here:

It disables all errors on bootup, No idea what other kind of errors are suppressed though.
