Lenovo B50-35 windows 8.1 doesn't work

[annam81]

Hi all, since yesterday I have a problem with my computer. First was blue screen, I turned off power. After that computer was turning on normally but didn't react when I want to choose something. Somehow My antivirus was ok and I could started full scan. It tooks more than 12 hours to finished but didn't found any problem. I restarted computer and later on some updates were installed. Now is almost death- when I tick some icon it's reconize my move after 10 minutes, trying to open it and straight away closing this app. I don't know what can I do. HELP!!!

Welcome to the forum if you can run this scan and post both files it creates it will give us some idea of the problem

Please download and save FRST 64bit or FRST 32 bit to your Desktop.

http://download.bleepingcomputer.com/farbar/FRST64.exe

Right click to run as administrator (XP users click run after receipt of Windows Security Warning - Open File). When the tool opens click Yes to disclaimer.
Make sure that Addition option is checked.
Press Scan button.
It will produce a log called FRST.txt in the same directory the tool is run from.
Please copy and paste log back .
The first time the tool is run it generates another log (Addition.txt - also located in the same directory as FRST.exe/FRST64.exe).
