BSOD while gaming (Phantasy Star Online 2)

[92968]

DIY-ed a desktop for my friend, he told me it BSOD-ed several times before.
Have never learned how to debug..
Better to seek help from experts here

He mentioned "D_pool_caller stop:0x000000c2"

Thanks!

After some DIY debugging, i think it is due to his wifi device being plugged into a USB 3.0.
I have suggested him to update the wifi device's driver and usb 3.0 driver.
Have also suggested him to test if the speed is bottlenecked when device is plugged into usb 2.0 port instead.

But I am unable to make out what the second compressed file is about, symbol errors D:
