nvlddmkm.sys BSOD

nVidia BSOD nvlddmkm.sys - Vista Hardware Devices

I was running an Asus laptop with an Nvidia Geforce 8600M GT video card (with a driver from April 30, 2009 obtained via the Asus Update utility) in it running Windows Vista Home Premium. Everything was fine. Suddenly it crashed and i got a BSOD msg referring to
nvlddmkm.sys

Looks like some glitch with the Nvidia display driver and Vista.

I found this forum with the solution.
What worked for me was:
- Boot into Safe Mode
- Run, cmd, sc delete nvsvc
- restart computer
- In the Display properties, change it back to Aero.
- Done

Everything seems fine after this fix.

Asus laptop built-in webcam upside down

I use an Asus laptop. My built-in webcam was working fine until recently. Now it shows upside down. I had recently updated a lot of drivers. So, I rolled back the driver (Control Panel\Device Manager\Imaging devices... and it works properly now.)
I am using Windows Vista.
If you are having a similar problem in Windows XP with a built-in webcam on an Asus laptop, try rolling back the driver.

I found a lot of info relating to this problem on Linux, and the solution there was to re-program something.

Direct Console MSNHOOK.dll fail

If you have an Asus notebook computer and you get this message, or ending in "failed to load", do not be alarmed.
What has happened is that with a new anti-spy-ware definition update, your anti-virus and/or anti-spy-ware program now thinks that this Asus notebook utility is a trojan (spy-ware).
To fix this you will need to go into your anti-virus/anti-spy-ware program and add the path to the Asus Direct Console folder, as well as the paths for LCMP.exe and MSNHOOK.dll to the exceptions.
After doing this, download the latest Direct Console (also goes by other names like Direct Messaging...) version from the appropriate Asus site and do a repair install to put the msnhook.dll file back (or just restore it from the virus vault). Reboot and the message should be gone and Direct Console should be running and properly functioning.
