0X9F with pci.sys BSOD

Hi and Welcome to SF Fang
This can be anything, but I would believe device drivers, as the bugcheck code is 9F.
One simple thing to check is to make sure every hardware are fully seated on motherboard.
I have seen this case twice today, one of them was solved by Repair Install , meanwhile the other was to update networking driver in safe mode.
I have looked at your minidump file, and I see that you have some out of date drivers, please download and install fresh copy of them:

Uninstall AVG, then run this tool: http://download.avg.com/filedir/util...removerx64.exe

Remove ZoneAlarm too, then use this tool: http://download.zonealarm.com/bin/fr...cpes_clean.exe

Install Microsoft Security Essentials instead: http://www.microsoft.com/security_essentials

Please remove any CD virtualization programs such as Daemon Tools and Alcohol 120%. They use a driver, found in your dmp, sptd.sys, that is notorious for causing BSODs. Use this SPTD uninstaller when you're done: DuplexSecure - Downloads

Update your ATI drivers: Graphics Drivers & Software

Look on your computer manufacturer's site for updated nVidia storage and RAID drivers: Drivers & Downloads
