You use System Restore to when it worked. Diagnosing with this much detail means we only have a few choices.
Of course we could restore it to factory but must folk don't want that.

I recently bought an Acer Aspire 5750Z-4835 and it has been working properly until 3 wks ago. It will not shut off/power down unless I do it manually, it will not wake up, the screen will not come back on, after either going to sleep or after I close the lid/cover. I have tried contacting the techs at Acer, in India it seems, and they have either been of no help or don't know their own system or won't help. So if you can help me I would be grateful. Thank you for your time.
