I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

RaminTechnical AdvisorCommented:
It seems the cause is sdiagnhost.exe

1. Press the Windows button + R on your keyboard, and type cmd.
2. Choose Command Prompt (Admin). You must run the command prompt in Administrator level.
3. On the command prompt type sfc /scannow and hit enter.                                          
4. if SFC found error then type DISM.exe /Online /Cleanup-image /Restorehealth and Hit Enter.
5.restart your computer .

If none of the above fixed the issue then try Windows 7 Repair install.

By looking at the minidump, i could see that this error

BugCheck 3B, {c0000005, fffff80002c9e915, fffff88007a79b70, 0}

Probably caused by : ntkrnlmp.exe ( nt!FsRtlLookupPerFileObjectContext+a5 )

Looks like it's Windows 7 machine? if so, the DISM command won't work. First try to run chkdsk C: /r /f to detect and fix NTFS file system issues.
Also, update all the drivers to latest (especially Graphics, printers etc..)
RaminTechnical AdvisorCommented:
Yes, don't run DISM on Windows 7, but run SFC.

For that error, also run memtest86.exe to test for memory hardware errors. Memory failures can cause the locking up you describe .
