Core i7 3820 ASUS Sabertooth X79 Motherboard 16gb Samsung 30nm RAM 2x Diamond AMD HD 7970s in XF 2x Samsung 830 256gb SSDs Seasonic X 1050 PSU Custom Liquid Cooling loop Windows 7 Ultimate x64 Lately I have been crashing every time I start up a steam game, specifically Metro: LL, Borderlands 2, and Bioshock Infinite. This was not always the case. I could easily play several hours uninterrupted but now I'll crash immediately at the startup menu and freeze. I've tried to look at event viewer and windbg, and in the beginning, everything pointed to both a file called "atidxx32.dll" and corrupted memory. After reinstalling Catalyst, though, I continue to hard freeze, but I don't get an event correlated to the game which I was playing before the crash. These freezes are sometimes only ended by physically restarting my machine, but other times I can stop it if I hit CTRL+ALT+DEL quickly enough. Even when I manage to prevent a freeze, no event appears regarding the game. I've done everything I could to try to stop the problem, yet it persists and I am now at a dead end. I have: Running Windows Diagnostics tool; yields nothing (lol) Updated Windows Revoked overclocks on CPU (5.0ghz to stock), GPU (1300core 1600mem to stock), and memory (2000 10-10-10-27-1 to stock) Reinstalled Catalyst drivers (have tried 13.5 beta, 13.6 beta, 13.3, and 13.2) Reinstalled Steam Reinstalled Chipset Driver Reinstalled Audio Driver Reinstalled USB Driver Reinstalled SATA Controller Driver Reinstalled Marvell SATA Controller Driver Ran Windows Memory Diagnostics; no errors Ran CCleaner Registry fixer Check for viruses with both Malwarebytes and MSE, both of which are up-to-date Stress tested the system with Linxx and Intel Burn Test, along with 6 hours of prime 95 Tried disabling several combinations of two 'High Definition Audio Devices' and a Realtek Audio Device Tried reinstalling WINDOWS Nothing.
