CPU: Intel Core i5 2500k Motherboard: ASUS P8P67 Rev 3.0 Ram: 2x4 GB DDR3-1600 G.SKILL timings 9-9-9-24-2T with 1.5v GPU: XFX Radeon 6990 PSU: OCZ 850w modular 80+ certified OS: Windows 7 64-bit Professional Drive: 120 GB OCZ Vertex 3 Max-IOPS SSD connected to the Intel SATA III controller Since building my computer late December, I have had random system freezes and now constant blue screens. If the system froze, the mouse could still move, but no interaction would work and no application could be launched. The hard drive light would be fully lit, not even flickering. I have updated the firmware on the SSD to latest, updated BIOS to latest, removed any overclocking the ASUS board did by default, verified RAM timing and voltage, reinstalled Windows twice, updated Intel storage driver and Radeon drivers to latest, have all Windows updates installed, Norton AV has been the very first installed program before a network connection is plugged in, and Windows is set to High Performance to prevent power saving modes. The system could BSOD multiple times per day, but fairly randomly. Not after a certain amount of time or during a specific activity. Once after exiting a game, once after opening an image in Firefox, a few times trying to watch Netflix in Chrome. Other times I can play a game for 4 hours, watch Netflix for 2 hours, and browse the internet without issues. The error is not consistent, so I cannot replicate it at will to test parts. I had 3 BSODs on Sunday and one today, though the one today did not generate a minidump. The BSOD is: The computer has rebooted from a bugcheck. The bugcheck was: 0x000000f4 (0x0000000000000003, 0xfffffa80096f3920, 0xfffffa80096f3c00, 0xfffff800031e88b0). A dump was saved in: C:\Windows\MEMORY.DMP. Report Id: 022612-6552-01. And I will zip up and attach the 3 minidumps I have. System logs only show the BSOD and that Windows needed to restart, no other information. The BSOD also does not automatically reboot, even though Windows was set to auto restart. I have never had a crash in the middle of the game (yet), so heat and the number of max wattage of the PSU I do not see as a problem. I have seen BSODs caused by the OCZ SSDs and tried all the suggestions from OCZ, but the drive passes all chkdsk and benchmarks. Memory passed the Windows memory tester, but I have not tried Memtest86. I am completely out of ideas on how to diagnose the problem and just don't have the expertise or spare parts to test with. I'm tempted to ditch the SSD for a Raptor, but would rather not throw parts as that could get very expensive.
