A computer of one of my users during the boot of its Windows XP SP3 is insistingly showing a messagebox with different illegible symbols in body and title é requiring to press OK
If to leave this messagebox without pressing OK, then the title and body with illegible content are changing every half minute.
Eventvwr doesn't show anything helpful
The system is checked and treated by multiple antivirusesm registry cleaners, registry defragmenting utilities, system and hardware checking applications, etc.
I've tried all I could find by search on internet. For example, How to Suppress Error Messages During Boot Process. Nothing succeded so far
This also happens if to boot
- from DVD
- in safe mode (though in safe mode the content is not auto-changing periodically)
- to disable any processes on startup!
It is after loading drivers but before Welcome screen.
Tweaking BIOS settings did not help.
In boot.ini I created 2 entries for loading Windows XP with /bootlog switcher and another without. So, I could get boot log on complete loading and until the messagebox (by hard restart on messagebox and choosing the next booting without bootlog in order to avoid its overwriting).
Though the last record on hard restart is always different one.
What are the possible ways to identify the source of a popup (or get rid of it without finding the cause)
