In the last stage of booting my WindowsXP, a blank page appears on the screen. It is about a third of the screen size and with [[ in the page title.
After clicking on OK or only “enter” the “welcome” appears immediately and the system boots correctly.
Sometimes the page disappears after 2-3 minutes waiting.
It is only annoying and everything else works correctly, but I prefer to boot without such disturbance.
Can anybody help?
Thanks

If it is a new problem try a System Restore to a point prior to the problem.

start > all programs > accessories > system tools > system restore
