3rd SP3 i have setup and this one has a strange problem. for no reason the screen will go blank for a split second. no rhyme or reason. could just be sitting there or i could be using it. ran all updates. looked at power settings. still happening. this happened since the time i turned on on for the first time. so i know it is nothing i have installed. any suggestions would be welcome. i fear that all the configuration i have done on this one will be wasted as there is probably a hardware problem with this unit. fun fun. another issue is how the hell do you contact support for these devices? I am stuck on the support page with the little progress bar going crazy but it never gives me options. this is happening on the sp3 and on my office computer. very frustrating to not be able to reach support.
