I had some computer trouble this week. I have Windows 8 and normally you don't shut it right off , I did this time and come back to it last on Sunday last week and it said it was repairing disks and would take about an hour, it was more than that after we got back from church it had finished and said it couldn't fix it, tried to install Windows 8 and other disks to try and restore it ,said it was not valid. We took it last Monday, heard from then yesterday, had to take over the Windows 8 disk and they had to wipe the memory clean so lost pictures. I have it back now my printer won't work ,not compatible with Windows 8,I had got it when I still had windows 7 and software for the printer was still in in the computer when I upgraded it to 8 so it worked and and now it treats like a new install so a printer I just bought 2 months ago is useless for me, can't edit pictures down when Olympus, lost a serial number I need to go on and finish it.
