Windows 7: BSOD - MEMORY_MANAGEMENT and PAGE_FAULT errors (x1A and x5) under load

BSOD - MEMORY_MANAGEMENT and PAGE_FAULT errors (x1A and x5) under load

I've been getting these two errors a lot lately. They always appear in the 0xFFFF FF## #### ##### block of memory. Running Memtest did not reveal anything, but that's not always reliable.

Seems more likely to occur when the computer is under load (like when I run Autodesk products) but, really, they will creep up any time.

I have an IT guy, but he's .... limited. I have some IT background myself, so I was hoping to get a little help.

I tried running the Seven Forums diagnostic tool but I ran into unhandled exceptions (see my post on the diag tool here: SF Diagnostic Tool - Using for Troubleshootingl)

So, I ran some of the common diag tools and uploaded them in an attached zip with this post.

Any help is greatly appreciated.

These automatic driver updating programs usually install outdated and unstable drivers. The best method is to install drivers and check for updates from the manufacturer's website of that device.

Thanks for the help! Still having trouble....

SFC reports that it cannot repair one file (Full log for day of run is attached, excerpt of log shown below).

The weird thing is, this is not a file name, but it looks like part of a Windows Update file name. I did a registry search for the corrupted file and got this key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\SideBySide\Winners\amd64_da316fac233873 1c065cc6a0e8152c83_31bf3856ad364e35_none_7221e87d5886914b

Any idea what is going on here? All malware scans (TDSKiller, Malwarebytes, McAfee, etc) come up clean.

However, one odd thing I noticed is that my CCMEXEC.exe file is constantly trying to shut off McAfee. The version I have it 5.0.7804.1000. Online it appear this file should be around 1MB, but mine is 1.8MB. If this is a virus, why isn't it getting flagged by any malware scanners?

ccmexec.exe and inventory.exe - what are they and what do they do? - Jonathan Hardwick - Site Home - MSDN Blogs

ccmexec.exe is a Windows file for updating software.

Have you tried running the same command again three separate times?

If SFC could not fix something, then run the command again to see if it may be able to the next time. Sometimes it may take running the sfc /scannow command 3 or more times to completely fix everything that it's able to.
