2 days ago, I left Blizzard Background Downloader on all night and used Auto Shutdown to turn off the computer at about 6am. I've done this 100's of times before with other downloads, but never the Blizz downloader. I have also recently changed the nVidia settings on my GTX 260 gpu to "high performance" parameters, ie making it more nVidia controlled than application controlled (world of warcraft). It greatly improved my performance, but I don't know if either of these are related to my BSOD problems. I can run in safe mode just fine, have been for hours, but upon a regular restart I might get 1-2 minutes of normal use before BSOD. Here are a few dumps, I hope someone can look them over. I have tomorrow off and I don't want to spend it reinstalling Win7 ... 082212-42687-01.dmp 8/22/2012 2:17:43 PM PAGE_FAULT_IN_NONPAGED_AREA 0x00000050 fffff8a0`a756e560 00000000`00000000 fffff800`03ca2c84 00000000`00000005 ntoskrnl.exe ntoskrnl.exe+7f1c0 NT Kernel & System Microsoft Windows Operating System Microsoft Corporation 6.1.7601.17835 (win7sp1_gdr.120503-2030) x64 ntoskrnl.exe+7f1c0 ================================================== Dump File : 082212-42687-01.dmp Crash Time : 8/22/2012 2:17:43 PM Bug Check String : PAGE_FAULT_IN_NONPAGED_AREA Bug Check Code : 0x00000050 Parameter 1 : fffff8a0`a756e560 Parameter 2 : 00000000`00000000 Parameter 3 : fffff800`03ca2c84 Parameter 4 : 00000000`00000005 Caused By Driver : ntoskrnl.exe Caused By Address : ntoskrnl.exe+7f1c0 File Description : NT Kernel & System Product Name : Microsoft Windows Operating System Company : Microsoft Corporation File Version : 6.1.7601.17835 (win7sp1_gdr.120503-2030) Processor : x64 Crash Address : ntoskrnl.exe+7f1c0 Stack Address 1 : Stack Address 2 : Stack Address 3 : Computer Name : Full Path : C:\Windows\Minidump\082212-42687-01.dmp Processors Count : 4 Major Version : 15 Minor Version : 7601 Dump File Size : 290,816 ================================================== ================================================== Dump File : 082212-37875-01.dmp Crash Time : 8/22/2012 1:29:17 PM Bug Check String : PAGE_FAULT_IN_NONPAGED_AREA Bug Check Code : 0x00000050 Parameter 1 : fffff8a0`ad604560 Parameter 2 : 00000000`00000000 Parameter 3 : fffff800`03090c84 Parameter 4 : 00000000`00000005 Caused By Driver : ntoskrnl.exe Caused By Address : ntoskrnl.exe+7f1c0 File Description : NT Kernel & System Product Name : Microsoft Windows Operating System Company : Microsoft Corporation File Version : 6.1.7601.17835 (win7sp1_gdr.120503-2030) Processor : x64 Crash Address : ntoskrnl.exe+7f1c0 Stack Address 1 : Stack Address 2 : Stack Address 3 : Computer Name : Full Path : C:\Windows\Minidump\082212-37875-01.dmp Processors Count : 4 Major Version : 15 Minor Version : 7601 Dump File Size : 271,280 ================================================== ================================================== Dump File : 082212-33781-01.dmp Crash Time : 8/22/2012 4:21:18 AM Bug Check String : PAGE_FAULT_IN_NONPAGED_AREA Bug Check Code : 0x00000050 Parameter 1 : fffff8a0`ad836560 Parameter 2 : 00000000`00000000 Parameter 3 : fffff800`030a6c84 Parameter 4 : 00000000`00000005 Caused By Driver : ntoskrnl.exe Caused By Address : ntoskrnl.exe+7f1c0 File Description : NT Kernel & System Product Name : Microsoft Windows Operating System Company : Microsoft Corporation File Version : 6.1.7601.17835 (win7sp1_gdr.120503-2030) Processor : x64 Crash Address : ntoskrnl.exe+7f1c0 Stack Address 1 : Stack Address 2 : Stack Address 3 : Computer Name : Full Path : C:\Windows\Minidump\082212-33781-01.dmp Processors Count : 4 Major Version : 15 Minor Version : 7601 Dump File Size : 271,280 ==================================================
