i even try to format the hard drive again and to install win 7 like i buy the computer, but still i have the same problem.
another thimg that i try is to Remove the battery and ac adapter and perform a power drain by holding the power button for 30 secs. and boot into the BIOS and load defaults settings by pressing F9 then press 10 to save and exit to

Thanks for using the Lenovo forums.
If I understand correctly, this has been going on for over 1 year?
It may be that the graphics card is faulty, however, I can see that your device is not listed in the list of units tested and ready for Windows 10, so this may be causing issues as well:
I would recommend that you try to get a Win 7 recovery media from your local Lenovo support, and see if they are able to send one out for you to try.
Otherwise, I would recommend that you get in touch with them in order to organise a repair for your unit.
Below is the link to the phone list where you can find these numbers
Hope this helps, let us know how you get on.

Thanks, but you done help me to solved the problem.
you suggest me to install win 7 because maybe the problem is win 10, but I have written in my first post that i tryed this solution already and i have know win 7 install on my comuter and this is not solved the problem. another thing is that the nvidia card stop to worked also in the same day i upgreded from win 7 to win 8 and also dont worked in win 8.1 so the problem is not win 10!
second thing that you sugsset is that maby the graphics card is faulty, but this is probably not the problem because the nvidia card worked just fine until the day i upgraded to win 8.
It makes no sense to assume that in the Exactly day that I upgraded the win 7 to win 8 the graphic card went bad!
there must be another reason! can you help me with better sullotion???
