dxgkrnl.sys not loading on bootlog file (4 times)

Hey.

been getting a 40 second or so black screen hang when starting up my windows 8.1 machine. I thought it was video card issues, and have done everything I can possibly think of (gpu related) to fix the problem.

I ran a bootlog just now, and everything seems in check except one thing not loading:

BOOTLOG_NOT_LOADED \SystemRoot\System32\drivers\dxgkrnl.sys

This error pops up 4 times within the bootlog, so I'm figuring this has something to do with the hanging, but I can't for the life of me figure out how to fix this, and was hoping somebody could help.

Thanks

First thing I would do is run sfc /scannow. I'm guessing you re-installed graphics drivers. What graphics card and latest drivers?

Hi. That's correct, I reinstalled my drivers. Nvidia GTX 770 and I am running the latest drivers.

Running the scan, I will update you when it's done. Thank you very much for taking the time out to help.

Everything is fine with the scan - no errors.

Microsoft has this tool: Run DirectX Diagnostic Tool

And that is pretty much crap also. :(

Beginning to look like a refresh minimum. Do you have a restore point before this started?

One last thing to try. Uninstall drivers and select the option to delete drivers. Reboot and see if fixed.

I'll run that tool, thanks. No I don't. It happened right off the bat with my new build but I've just been so busy with uni to fix the issue. Now that I have a few weeks off I figured I'll try to fix it.

One last thing to try. Uninstall drivers and select the option to delete drivers. Reboot and see if fixed.

What drivers should I uninstall? I deleted dxgkrnl.sys from system 32 after creating a restore point - not a good idea, lets just say the restore point had to be used.

The graphics drivers in Device Manger.

You say new build. Are you sure everything is up to date like BIOS for the motherboard? Have you played with the graphics settings there if any in BIOS? Was this a fresh install of Windows and started right away?

Yes, everything is 100% up to date. There are no graphics settings in the bios. I've installed w8.1 in UEFI mode, disabled CSM and enabled fast boot, still slow bootup. This was a fresh install and the black screen started right away although at the start it wasn't as long.

Well, kind of stumped here. Would help maybe if you posted more specifics about the system like make/model motherboard, RAM, etc.
There is a hot space on lower left corner to do that.

Maybe others with your particular MB are having same issue.

Added specs as requested.

Edit: Just realised there was a new bios update about a week ago - will flash and report back.

Nice motherboard. There is also a chipset driver dated last month. I would also install the Intel VGA driver they have posted.

Thank you :)

Updates:

  • BIOS flashed to latest
  • Chipset drivers updated
  • VGA drivers could not be successfully installed. I ran into this problem on the first day, and guys over at another forum said it's normal because I'm using a dedicated graphics card. I can apparantely only install it if I were using the integrated graphics controller which I'm not, so I just left it.
  • The error it gave was "The computer does not meet the minimum requirements for installing the software" - simply because it's not being used, my monitor is plugged into my graphics card's HDMI port, and not my motherboards one.

Only other constructive input at this point is try with ant-virus off. And does it pop the same error when you boot to Safe Mode?

Maybe someone else will jump in with fresh ideas short of a complete clean install. How did you install 8.1? Do you have discs or did you have to update from 8 media?

I've done a diagnostic bootup through msconfig, disabling everything, and the problem is still there (although 10 seconds or so shorter). The same also happens on safe mode.

Well, that tells me the problem is at a much lower level. How did you install 8.1, directly or update from 8?
