Win7 boot crash due to atikmpak.sys
Hi,
I have a macbook pro early 2011 runing windows 7 (64bit) with bootcamp (OSX:snowloepard)
When booting in win7 mode, a blue screen shows up saying that it is caused by atikmpag.sys . This happens all the time since yesterday. I didn't install any new software.
I can boot windows in safemode without any problem.
In safemode I deleted (renamed to.old) the file atikmpak.sys. (in /windows/system32/drivers/)
After that it booted in normal mode - with success - but with wrong display resolution.
Devicemanager says there is a problem with the AMD RadeonHD6750M driver.
I tried to reinstall all bootcamp drivers which results in the known blue screen on startup.
I deinstalled the graphics card in the device manager and I tried to install the AMD drivers for the HD670M - and it also results in the bluescreen after rebooting.
Windows will only start up in normal mode after i have deleted the atikmpag.sys. in safemode.
Oh and OSX is also not booting. - The apple logo comes up - and after 3-4 seconds the screen turns completely light grey.
What should i do?
Is this a hardware or a software issue?
