Windows 7: Audio Driver Malfunction on Restart

Audio Driver Malfunction on Restart

Hi Guys,

----------------------
GPU: Gainward NVidia GeForce GTX 460
SOUNDCARD: Asus P7P55DE-LX - Inbuilt to Motherboard
----------------------

Issue I am facing: On system restart, the audio drivers for both NVidia & VIA are 'deleted' and I have to reinstall the drivers every time I restart/start my computer - which is getting very tedious.

On running a bootlog (attached) i found that the drivers load but preceeding each audio driver load there was this driver called 'ksthunk.sys' which seems to malfunction.

Quote:

Also I have noticed that other drivers also are not loading on system start-up. How can I resolve this?

I've honestly got no clue on how to proceed, any help is appreciated.

PS - Drivers are up-to-date

Thanks

ksthunk.sys can be malware. Suggest you run a malware/spyware scan with a program such as Malwarebytes, as a start.

See this posting on it. ksthunk.sys Windows process - What is it?

Hi fireberd,

I have scanned ksthunk.sys which was in C:\Windows\System32\drivers and i've received no errors both on Avast and Malwarebytes.

Whats next to do?

Thanks

Rename the file to something such as "oldksthunk.sys" and then restart the PC and see what happens. According to the site in the link it may work without that file.

If you run into other problems, rename it back to "sthunk.sys".


A side note, I see you have a 64 bit OS but only 4GB of RAM. This is not the cause of your problem, but the reason to use a 64 bit OS is that it can address and use more than 4GB of RAM. With only 4GB (and if it can't be upgraded) the 32 bit OS would have been the best choice. A 64 bit OS uses more of the available RAM than a 32 bit OS and thus you have less available for programs.

Hi fireberd,

I cant rename it or modify it. I get an error (attached).

What do I do?

Thanks.

After looking back over your listing, that file may not be the problem.

Reinstall the Intel Motherboard Chipset Drivers, then restart and see if that helps.
The chipset drivers are listed on the ASUS downloads.

I recently updated the chipset driver, is it necessary to reinstall it again?

Did this happen after the chipset update?

No, this started happening I THINK after I updated my graphics card.

Rollback the video driver (you can do that in the Device Manager) and see if that makes a difference.

Go to the Device Manager, RIGHT click on the entry for the video card and then Left click Properties.
