Solved BSOD 9F Driver power state failure

[ar7]

Hi
I have had for 2 days 20% CPU of SVchost. exe
and now a BSOD 9F Driver power state failure
Before i did this month MS update (only one critical update) and uninstalled Quicktime.
rebooted, running avira and no other virusscanner.
Any help is appeciated.
Thanks

solution

I have killed the windows update process "[FONT=&quot]'wuauserv'" [/FONT]with the task manager so the Svchost went down,
and i resest the computer to an older date, without the quicktime change,
so everything up to now works as normal again
hopefully stays that way.
Thanks for being able to post here
