Thanks for your advice,
I have updated completely everything possible… Beginning with BIOS, ending with Vista. And nothing new…
So at least I have my PC up to date 🙂
One more thing it seems that it is problem only on my PC, otherwise as far as I have been asking >> no similar problem detected, even on Vista machines.
I am suspecting that the core of the problem might be burried somewhere in services, but I don’t want to mess around in there… Does anyone have some clue, what may be the cause?
Thanks
