Hi I am facing a similar problem with Windows 7 64bit Professional Edition. I have a Complete memory Dump file of my BSOD and i analyzed lttle bit of that. It shows the issue is caused bcoz of the "nt!IopDeleteFile+168 fffff800`02d99458 488b8bb0000000 mov rcx,qword ptr [rbx+0B0h]" SInce the "nt" is Windows base OS dll file i think this could be an Microsoft issue. Below is my BSOD report Microsoft (R) Windows Debugger Version 6.11.0001.404 X86 Copyright (c) Microsoft Corporation. All rights reserved.

Hi B.Akbar, This forum is dedicated to Windows Forms technology. I'm moving this thread from Base "Windows Forms" to Windows 7 IT Pro Forums, since this issue is related to it. There are more Windows 7 IT experts in that forum.

nt!IopDeleteFile this looks like file system issue. Run chkdsk C: /r /f to detect and fix NTFS file system issues."A programmer is just a tool which converts caffeine into code" I'm going to leave the forum on 31th March 2011 if I don't get a Feedback about the SPAM of 2 MVPs. So if you want an answer, be fast so that I can help you before I leave the Technet forum.

when the notskrnl is named this means the main NT kernel has crashed but if that file was at fault you would be having far more problems than a few bluescreens Printer Support|Computer Repair
