Well the first one was faulted at your nVidia display driver
BugCheck EA, {894da6e0, 894013a0, 8960fd98, 1}
Probably caused by : nv4_disp.dll
PROCESS_NAME: Wow.exe
And the next one was your sound
BugCheck 10000050, {b97649c8, 0, 9d171d83, 2}
Probably caused by : kmixer.sys
PROCESS_NAME: System
Have you updated all your device drivers?
You can find all your device drivers here:
>> Driver links by manufacturer
I have seen similar BSoDs caused by Antivirus and Firewall programs as well
Since you are using AVG Free, you might want to try the following (before giving up
)
Uninstall AVG Antivirus through Control Panel > Add/Remove Programs
Then run the AVG Remover Tool:
>> http://www.avg.com/filedir/util/support/avgremover_en.exe
Restart
Download and install Free Avira Antivirus:
>> http://www.free-av.com/
Install; Update; and run a
full scan. I would be
very interested if it finds any Viruses
Try that (well those two things > Drivers and Antivirus)
Edit
Oh and use "Edit" instead of relying to yourself
