Lost power last night... so windows was not shut down properly. Upon startup, I lost some services - wireless, print services, some programs not running, etc... I went online to search for solutions. At some point I reached a 'windows validation' failure screen (in retrospect, some spyware/virus?), and followed suggestions to uninstall my last windows update. Upon restarting, I get past the 'windows is starting' flower, but then get a blank screen with the mouse cursor visible. I have tried starting in safe mode, but get the blank screen and mouse cursor as before. I have tried windows recovery console, but can't get past the request for admin password (doesn't recognize the password). I have tried booting from disc - this worked - and I run startup recovery. No errors noted. I restart and get the blank screen with mouse cursor. I'm running windows 7 home premium... thank you for any help/suggestions.
