BugCheck 9F, Probably caused by pci.sys but atikmpag.sys is what caused the Blue screen.

Try updating your Video drivers as the most recent file dates are showing 2011, and ensure that you have the latest Device drivers for your Motherboard, eg: Chipset Network

If you are using a third party Firewall, remove it and use the included Windows Firewall. That's good enough.

If you have a suitable Nvidia  video card then go for it.

pci.sys can be caused by hardware, or it's drivers
disconnect all external devices to start with (usb devices also)

at what moment are you getting this?  during install, or normal power up?
during power up, you could try a repair install :

A driver has failed to complete a power IRP within a specific time (usually 10 minutes).
Arg1: 00000003, A device object has been blocking an Irp for too long a time
Arg2: 8559ab58, Physical Device Object of the stack
Arg3: 82f6d9e0, nt!TRIAGE_9F_POWER on Win7, otherwise the Functional Device Object of the stack
Arg4: 87799c20, The blocked IRP

Debugging Details:
IMAGE_NAME:  pci.sys
I agree with rrjmin0 analysis about ati need to work in that direction.
