JoeyT ... Welcome to ROG ..
First I'd like to say, p8z77-v Deluxe, yum...
You do not say what country you are in, and the forum country/region is still not working all the time..
So .. second, where are you?
Collect all your reference numbers ect...from your case and PM (private messege) Mason@Asus to see
what can be done. (He is in NorthAmerica but usually can help point you in the right direction if you are not.)
Is the memory removable ? and have you run any memory tests ? or have other memory to try ?
Also .. are you online when this happens ? Have you updated the network driver ? or did windows
update the driver about the time this started ?
Network and Memory are two of the places bsod can come from .. other than os errors or conflicts...
best of luck .. c.
