How to troubleshoot an error that appears only at Restart or Sign out?

I get an error pop-up error message not every, but almost every time I Restart or Sign out. It's the screen with blue background and on top of Restart or Sign out text an error window says:

Explorer.exe - Application error. The instruction at 0x000… referenced memory at 0x000... The memory could not be written.

Sometimes the error code is just zeros, sometimes random numbers. I have tried so much already to troubleshoot this. For example these did not help in any way:

• MemTest86+ (no problems)
• Disabling any Services, Autoruns/ShellExView entries
• Low resolution mode
• BIOS settings are fine, no overclocking etc.
• DISM.exe and sfc
• etc.

However, these do make the error go away:

• End process for explorer.exe before Restart or Sign out
• Safe Mode
• Creating a new user profile (almost the same as clean installing Windows, many full days of work)
• Uninstalling NVIDIA graphics driver (then the card is unusable, of course)
• Disabling Device Manager / Display Adapters / NVIDIA GeForce GTX 1080

I already contacted NVIDIA and the graphics driver is not the culprit. Something has gone wrong with the user profile as the same driver works just fine in a new profile (and there's nothing wrong with the driver anyway, it's just the Restart or Sign out process that has a problem).

What can I do to fix this? One useful thing would be to have a step-by-step procedure for the Sign out. So that it'd ask before continuing to the next step and list what it's doing. Or if I could just disable whatever it does when the error appears.

 

BIOS error codes

So I have motherboard with installed small LED screen, which presents BIOS error codes.

Where can I find a list of those errors. And I don't mean beep codes, but the "number" codes.

Ex after installing sound card, the motherboard startup fails with the code 15.

Example picture of code is here.

 

Outlook not connected in Microsoft Exchange Server

I am new to Exchange Server 2003 and I have a friend with a network server that I don't know how to re-establish a user to the network. I moved one of his non used computers to this station and now when I try to log in the user I get the error that the name can't be verified because Outlook is not connected or online. This computer used to be online with a different user. Can anyone tell me the steps to check this? Thanks.
