The first week and a half with my SP2 (8gb/256gb) were great. This week...not so much. I've completely restored to factory twice due to stability issues. Now I have a new problem. When waking it from sleep last night, everything was fine. I tried to launch the TuneIn Metro app, which opened then immediately closed. I did that twice with the same result. Thinking I'd just restart the system to see if it would clear the problem, I swiped in from the right edge, touched Power then Restart. Well, actually, it said "Update and Restart". OK, sure. When the SP2 came back, it loaded to the lock screen just fine. I swiped up, entered my password and the Start screen loaded but was completely blank. The Apps screen is completely blank as well. I can get the charms bar to show (swipe in from right), but searching for *anything* results in a search screen that is endlessly sliding dots across the top of the screen. No results ever show. I tried a hard power down (hold down power button for 10 seconds), then restarting. Same results. I tried a hard power down followed by the UEFI boot (volume up and power button), installed the default certificate (thinking maybe the drive was not 'unlocking' or something), saved and exited. Same results. At this point, I can't even get into the restore settings to do (yet another) factory reset. Has anyone had this problem? Any thoughts on additional troubleshooting or how to fix it? To be frank, my satisfaction level is dropping. The SP2 shows so much promise, but ever since that first blue screen (complete with emoticon, ugh) for a crash Bth<something><something> driver, this device (well, not *this* one; I'm posting from my iPad) has been...less than stellar. Help?
