Ostatnio często pojawia mi się problem z dyskami twardymi. Otóż, gdy klikam na ikonę dysku, aby go otworzyć wyskakuje okienko "Otwieranie za pomocą".
Wiem, że można otworzyć dysk poprzez "Start->Uruchom...->c:/" ... jednak wolałbym otwierać dysk bezpośrednio przez "Mój Komputer"

Bardzo bym prosił o sprawdzenie loga, bo może tam znajdzie się rozwiązanie tego problemu.

A co do tego prawokilka I open z

jak to zrobiłeś wejdź na partycje klikając prawym przyciskiem myszy i otwórz
następnie skasuj plik autorun.exe i uruchom ponownie komputer
powinno być już ok

[Macias]

OK, naprawiłem to co napisałeś w logu.

ALE ...

Na partycje nie mogę wejść również "PPM Otwórz"
A pliku autorun.exe nie mam na dyskach, jednak mam coś takiego:

AUTORUN.EXE-058C6C0E.pf - C:\WINDOWS\Prefetch -23kb

oraz autorun.inf C:\Install\Chipset\Intel (informacje instalatora)

Można coś na to poradzić?

[Macias]

Już problem rozwiązany, dzięki za pomoc z logiem ^^

POZDRAWIAM

[Asdef]

a bo nie było, bo zapomniałem dodać, że trzeba zaznaczyć opcje pokaż pliki systemowe i ukryte pliki... ale skoro poradziłeś sobie to szczegół

[Macias]

Witam, Jak zwykle mam taką samą prośbę - sprawdzenie loga z HJT.
Ostatnio komputer pracuje bardzo wolno, przeczyściłem dyski, usunąłem wpisy z autorun, ale dalej nie ma zmian. Może specjalista sprawdzić poniższy log? Dziękuję z góry.
