i've been working on this since the servers came live at noon, i can play from anywhere between 2 minutes and 15 minutes then the game crashes, no error code or anything like that. I have reinstalled my os, reinstalled all updated drivers, downloaded the ati rift app data, tried playing at lowest settings though it doesn't make a difference. nothing i have done seems to allow me to stay in the game without it crashing over and over. I have turned off all overclocking on my system re-installed rift on a clean hard drive with a fresh os plus windows updates with the latest drivers. here are my system specs.

my cards are not heating over 40c my processor is staying around 27c. it doesn't crash my computer just rift and then restarts right away (thankfully at least it's skipping que's when it loads back in.)

If anyone has any info on this problem or any possible fixes for this problem please let me know ASAP!
