MSI Z68A-GD65 Intel Core i7 2600K 16GB Corsair Vengeance DDR3 PC3-14900C9 Memory @ 1866Mhz 2x Sapphire AMD Radeon R9-290X Tri-X Graphics Cards @1010Mhz Asus Xonar D2X Sound Card Game Running from 4TB Western Digital Black Hard Drive Windows 10 Pro x64 Latest AMD Beta Drivers: Catalyst 15.8beta Previously Test Drivers: Catalyst 15.7.1 (Stable) PA: Titan Build: Stable (log.zip) First run was with crossfire enabled. Ran fine for about 5 minutes and then the UI failed. Couldn't interact with anything. Second attempt to play. This time with Crossfire disabled through Catalyst Control Center. Ran fine for about 3 - 4 minutes and then the game hard crashed. Not CTD. Full hard crash. Couldn't get back to Desktop even with ctrl+alt+del. Just black screen. Forced to Hard reset computer. EDIT: Just tested PTE build. Hard crash within one minute. Log added: (PA-2015-09-05_004528.txt) * Clarification regarding what I mean by Hard Crash: To be precise. Game hard crashes. But the crash is so severe, that I can't alt-tab out and I can't ctrl-alt-del out. Alt-tab does nothing, and if I attempt to perform a ctrl-alt-del, I get a black screen. I can see and move my mouse, but nothing else. I'm eventually forced to perform a hard reset on the computer in order to get it working again.
