Καλημέρα...
Λίγο πριν κάνω log in μου βγάζει ένα σφάλμα σαν αυτό του τίτλου παραπάνω

Τι μπορεί να φταίει???

Ευχαριστώ...

Έχεις κάποιο πρόβλημα με την φωτεινότητα στην οθόνη ;

[kostaspd]

Δεν έχω κάποιο πρόβλημα με την φωτεινότητα στην οθόνη ακριβώς,απλά όταν πάω να την χαμηλώσω απότομα με την μία δηλαδή κολλάει... Θέλει σιγά-σιγά....
Τώρα που το ξαναδοκίμασα μια χαρά δουλεύει η φωτεινότητα της οθόνης...
Αν δεν απαταμαι κάποιο μήνυμα με την κάρτα γραφικών μου βγάζει κατά την εκκίνηση....

[the_eye]

Αν δεν έχεις πρόβλημα με την φωτεινότητα αγνόησε το μήνυμα.

[kostaspd]

Αυτό θα κάνω...
