Hello, I decided to do a fresh install of Win 7 Ult SP1 32-bit. After I have all the Windows update files installed, I've been noticing that my computer just crashes. I install all my drivers, they haven't been updated. Then I leave the computer on by itself, when I come back, Windows experiences blue screen. I was able to analyst the three .dmp files. See below: Spoiler ================================================== Dump File : 030114-30531-01.dmp Crash Time : 3/1/2014 4:16:38 PM Bug Check String : PFN_LIST_CORRUPT Bug Check Code : 0x0000004e Parameter 1 : 0x00000099 Parameter 2 : 0x00049cea Parameter 3 : 0x00000002 Parameter 4 : 0x0003f639 Caused By Driver : ntoskrnl.exe Caused By Address : ntoskrnl.exe+d221c File Description : NT Kernel & System Product Name : Microsoft® Windows® Operating System Company : Microsoft Corporation File Version : 6.1.7601.18247 (win7sp1_gdr.130828-1532) Processor : 32-bit Crash Address : ntoskrnl.exe+d221c Stack Address 1 : ntoskrnl.exe+e3a59 Stack Address 2 : ntoskrnl.exe+221aee Stack Address 3 : ntoskrnl.exe+7c6a6 Computer Name : Full Path : C:\Windows\Minidump\030114-30531-01.dmp Processors Count : 2 Major Version : 15 Minor Version : 7601 Dump File Size : 143,392 Dump File Time : 3/1/2014 4:19:00 PM ================================================== ================================================== Dump File : 030114-40109-01.dmp Crash Time : 3/1/2014 2:13:32 PM Bug Check String : MEMORY_MANAGEMENT Bug Check Code : 0x0000001a Parameter 1 : 0x00000403 Parameter 2 : 0xc0008430 Parameter 3 : 0x002fc867 Parameter 4 : 0xc0000030 Caused By Driver : ntoskrnl.exe Caused By Address : ntoskrnl.exe+d221c File Description : NT Kernel & System Product Name : Microsoft® Windows® Operating System Company : Microsoft Corporation File Version : 6.1.7601.18247 (win7sp1_gdr.130828-1532) Processor : 32-bit Crash Address : ntoskrnl.exe+d221c Stack Address 1 : ntoskrnl.exe+88c8c Stack Address 2 : ntoskrnl.exe+885b4 Stack Address 3 : ntoskrnl.exe+7d850 Computer Name : Full Path : C:\Windows\Minidump\030114-40109-01.dmp Processors Count : 2 Major Version : 15 Minor Version : 7601 Dump File Size : 143,344 Dump File Time : 3/1/2014 2:16:34 PM ================================================== ================================================== Dump File : 030114-27593-01.dmp Crash Time : 3/1/2014 9:51:58 AM Bug Check String : Bug Check Code : 0xc000021a Parameter 1 : 0x98bd4950 Parameter 2 : 0xc0000005 Parameter 3 : 0x779d2d37 Parameter 4 : 0x0078f314 Caused By Driver : ntoskrnl.exe Caused By Address : ntoskrnl.exe+d221c File Description : NT Kernel & System Product Name : Microsoft® Windows® Operating System Company : Microsoft Corporation File Version : 6.1.7601.18247 (win7sp1_gdr.130828-1532) Processor : 32-bit Crash Address : ntoskrnl.exe+d221c Stack Address 1 : ntoskrnl.exe+2cee77 Stack Address 2 : ntoskrnl.exe+32028d Stack Address 3 : ntoskrnl.exe+1c9739 Computer Name : Full Path : C:\Windows\Minidump\030114-27593-01.dmp Processors Count : 2 Major Version : 15 Minor Version : 7601 Dump File Size : 139,320 Dump File Time : 3/1/2014 9:54:23 AM ================================================== Can anyone able to interpret these .dmp files and see what could be causing the crashes?
