Artemis disconnecting during upgrade

[mitranator]

Hi, I have this strange thing: with no reason, the startup menu, became a black square which freeze the system, no respond at all. Rebooting is working fine except when pressing the windows symbol for the startup menu. My problem is that if I try to upgrade to 4.02, or even the official rom from xda my orbit gets disconnected with no reason., i get this on the pc screen: " disconected ,check the cable and try again" . I have tried on Vista, on XP, I have tried several roms but...the same thing, at the stage when i get the upgrade progress bar on the computer I get disconnected and the htc screen goes white. And stays like that. Any Ideea why?
I am running the version 4.1 with cube, no problems until yesterday.
Thanks alot for your ideeas.
