3) I'll try to go also to hp forum but as I see from the event viewer the problem has to do with the key exchange not the malfunction of hp software . Thanks for your reply.

I hope that all this stuff will help people with the same or similar problem and again but with a great meaning Thank you solarmystic for your advices and this forum of course that lead me to you (a sevenpro ).What else I needed to solve my problem?!THANKS.
