Hi, i am a new user of Sevenforums. First of all i will make an apologize for my english.
I've read the instructions, but maybe i missed something.

I have seen so much BSOD the last few weeks, atikmdag.sys 0x1000007e. It appears while i'm starting my computer, or when i'm playing a games. Sometimes my system looks stable, but it never disappeard

I did some research the last days. And in my opinion is the Ati driver of my videocard corrupted. So i'd deinstalled windows 7, and also all my drivers.. But when i'm starting my computer, or playing a game, again a BSOD. Caused by driver atikmdag.sys.. What to do? A other problem is that sometimes after a BSOD, my computerscreen turned into black. After a couple reboots, the light will turn green on my screen..

I searched on the internet, but nothing helped. I'm really a noob with computers.

i'd run Driver Verifier. And my computer were going crazy. Several BSOD's and it was hard to work on my computer. , so i'd turn off Driver Verifier. But there are some logs.

After the thing with Driver Verifier i'd run SF again. So here is my new log. And i will upload a photo of my screen during Driver Verifier was enabled on my computer.

I need your help. The BSOD every hour is really annoying.
