Witam!
Od razu powiem, że nie mam zainstalowanego nawet SP1. Wiem, wiem, moja wina.
Problem polega na tym że przy uruchamianiu systemu w trybie normalnym system restartuje się. Do restartu dochodzi podczas logowania - Wczytywanie ustawień osobistych.
Narazie używam system uruchamiając go z opcji [F8]: Ostatnia znana dobra konfiguracja (ostatnie działające ustawienia)
Proszę o pomoc i z góry dziękuję
