Hello there,
yesterday I bought a brand new laptop. It is Lenovo Z50-70.
Specs:
Intel core i5 4210U
nVidia geforce 840m
4GB of ram
1920*1080 resolution

It was delivered with freedos and I had to install windows on it. I installed windows 8.1. After that I installed the drivers that came with the laptop. I updated everything, and on first reboot it showed Lenovo starting screen, then windows loading screen, and after that it went gray. It looks like defragmating, all kinds of colors and gray background. I put it to sleep, and turn it on again and everything went normal. Now I'm typing this on it and everything is fine, but whenever I restart it, it goes crazy like on first reboot after installing drivers. I tried to reinstall drivers for nVidia and integrated graphics but it's not helping. It's happening when I disable nVidia graphics and try to change resolution. Here is the image of the screen taken few minutes before I'm typing this. http://i.imgur.com/0KEurfr.jpg

Thank You very much, and sorry for my bad english, I'm from Croatia.

It look like something(probably graphic card or monitor) is defective. Have you look online for newer drivers then the one on the cd though. I would contact lenovo and see about returning the laptop.
