I note that the boot log indicates that driver dxgkrnl.sys failed to load 4 (separate) times. It could be loaded 1 time an attempt in the middle of the failed ones.

Nevetheless the PC seems to work fine.

Is there anything that I should do or check in my PC?

Many thanks,

Arturo

You could use something like RegScanner to see if it is being loaded from multiple locations in the Registry. From your log the first load seems to succeed. I would guess the failed loads would kick out right away since it's already loaded. Shouldn't slow down the boot much in that case.

If the "problem" is that hard to notice it may be safer not to fix it. If it starts to annoy that's another story. :)

I have seen my last bootlog. dxgkrnl.sys loads once and thenfails to load 4 times. I have only one dxgkrnl.sys signed by microsoft and insystem32\drivers, with its pair in WinSxS.
I have other non-signed andgenerally smaller dxgkrnl.sys, I do not know their origin, not always in pairs.

What can I do? rename the non-signed dxgkrnl.sys to see if PC worksfine and delete them after some days?
the registry keys with references to dxgkrnl.sys are:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WINEVT\Channels\Microsoft-Windows-DxgKrnl/Diagnostic

But is this messing you up any? Is the booting slowed down by these load failures? If not I wouldn't worry about it. I'm not a DirectX Guru. If there's one in the house perhaps they can comment. But I'm guessing some of these may have debug info etc.. or are for other special purposes.
