Hi, my Lenovo pc is only 2 months old. I shut it down as normal last night but today I can't get past the home screen. Don't know if this has anything to do with it but we had a power outage for an hour this morning before I turned on the pc. I've tried ctrl, alt delete but nothing happens. Also powered off and on a few times. Same result - just the home screen. Mouse is working but nothing to click on. Any help would be greatly appreciated. TIM.
