#StackBounty: #windows-7 #drivers #crash How to diagnose a faulty driver causing random restarts?

Bounty: 50

I am running Windows 7 x64. Ever since I installed the OS on my machine a couple of months ago, there has been random restarts occasionally.

  • My previous OS was Windows 8 and I did not have this issue.
  • The restart is not preceded by anything – no BSOD, no application hangs etc. It feels like somebody just hit the reset button on the motherboard

This leads me to believe that this is a crash in kernel space, i.e. either the OS itself, or one of the drivers, crashed. I suspect it might be the Nvidia display driver, or one of the ASUS motherboard drivers which rumors to be buggy according to a few forums.

What logs can I look for if it is a driver crash?

#StackBounty: #windows-7 #vmware-workstation #nvme Windows 7 SP1 with NVMe driver does not load on VMWare 14

Bounty: 50

I am testing Windows 7 Ultimate SP1 on VMWare first as right now I do not have real NVMe drive. After integrating MS hotfix KB2990941 & 3087873 the resulting Windows 7 SP1 64 ISO boots in EFI mode but does not proceed beyond Starting Windows logo screen on VMWare Workstation 14 when the disk controller is NVMe. It does not freeze as such as I see the slight steady movement of logo around itself, however it gets stuck there. Hotfixes are integrated into both Boot.wim and Install.wim

The main purpose of these fixes is to enable native NVMe driver support on Windows 7 SP1. Windows 10 ISO installs fine though with its built-in native NVMe driver. The slipstreamed Windows 7 ISO also installs fine if the virtual drive is IDE, SATA or SCSI. This step conforms that slipstreaming is fine.

Things I have tried so far but did not help

  • Integrated only KB2990941 and skipped 3087873
  • First install Windows 7 on SATA virtual drive then manually install hotfixes then add second NVME disk.
  • Found an OpenFabrics NVMe driver for Windows 7 64. Pushed it into Boot.Wim and Install.wim with DISM forceunsigned switch. Got BSOD for nvme.sys during boot.
  • As indicated on some sites, copied Boot.wim and Setup.exe from Windows 10 ISO into Windows 7 sources. This time it detects the drive and copies files but when it reboots, back to being stuck at starting windows!
  • Just for experimental purposes, tried my hands on an unofficial Windows 7 SP1 ISO available for download on third party sites. Still same result
  • Tried with both Windows 7 SP1 and Windows 7 SP1 + April 2016 roll up updates. Same result

I am now exhausted with options. It appears to me that the above hotfixes somehow do not work with VMWare Virtual NVMe controller in Windows 7 64 SP1. Can someone point me to any further troubleshooting options or any possible solution? Host OS is Windows 7 Ultimate 64 SP1 if that matters in anyway.

Thanks.

Update
Following works, it’s close but still not what I expect.

-Integrate KB2534111 in Windows 7 SP1 Ultimate 64 Bit

-Install the OS in VMWare 14 on virtual SATA HDD. Install the NVMe hotfixs.
Add NVMe virtual disk and restart VM. Now Windows 7 installs drivers and detects the virtual NVMe disk.

-However the moment I slipstream 2534111, 2990941 & 3087873 the resulting ISO stalls at Windows logo during first boot the moment it finds NVMe virtual disk.

#StackBounty: #windows-7 #laptop #audio #drivers #volume-mixer Why don't device and app sound mixers match?

Bounty: 50

My question is specified in the title, to be more exact I would like to show this particular screenshot of the sound mixer:

sound mixer mismatch

As you can see here, the volume of the IE reached the maximum level, but the device volume barely exceed the middle.

There are more crucial problems here – even if I set all settings to max, many games or movies are really quiet, and in accordance with the mixer, they don’t use whole volume of the device.

Why is it happening? Is there any other explanations except outdated drivers (my laptop is somewhat outdated, so there are a number of modern drivers not officially supported by the laptop)?

Technical details: laptop HP Pavillion dv7 6053er. I don’t know the exact model of my sound card, but my Device Manager says “IDT High Definition Audio Codec” + “Audio Intel(R) for Displays” and meanwhile I have beats audio logo on the bottom of the laptop.

EDIT.

To be more precise, I can toggle mixer to any level of any app without any problem, but i don’t understand why max possible volume of an app doesn’t indicate max volume in the device mixer. The master volume never reaches 100%, and if i change it, the app volume changes respectively

EDIT v2.
If it helps – i found that this problem doesn’t happen when a headset is plugged. Also here some other screenshots with other programs that tell that this problem is system-wide:
