well I got windows 8 pro, it worked great for around a month and then suddenly just stopped. every time I booted up it said diagnosing problem then pc repair failed. long story short I had to wipe my hard drive and I lost everything, games, game saves, school work, music, software, photos and so on. got very angry when Microsoft support couldn't help with the initial issue. so I wondering if anybody could help incase problem occurs again. and I will be backing up my drive this this time.
