System: Windows Vista Ultimate fully updated, Intel E6600, Nvidia 7600GT,
4Gb Ram, one LCD VGA and one lcd via DVI etc, nothing is over clocked
Problem: I built this system 6 months ago and it has been running perfectly
since. On August 27th my system tried to automatically update the existing
Nvidia driver from Windows Update (groan, I know, I’ve changed it and will
never let this happen again). My previous driver had been working perfectly.
I was at work and came home, my system was unstable, I was getting TDR’s,
artefacts on screen and before I could really work out what was going on my
system crashed with BSOD on nvlddmkm.sys error 116.
Now it is in a loop. No matter what I do or what display drivers I try Vista
always crashes on reboot with the same BSOD nvlddmkm.sys error 116.
With an Nvidia driver loaded I get a BSOD nvlddmkm.sys at boot with error
116. Regardless of driver – 97.46, 100.64, 162.22, 162.44 etc
If I let my system update itself, ie with a Microsoft minimal driver, it
boots but all I get displayed is a blank black screen with a mouse cursor.
Microsoft Nvidia WDDM driver 25/01/2007 So it shows a mouse cursor that
actaully moves about but the desktop is not present, blank, black etc.
If I uninstall whatever driver is currently installed from safe mode,
removing all driver files, removing those in system32 and renaming
nvlddmkm.sys in system32/drivers, and then reboot, my system boots up with no
driver file loaded for the adaptor at all. This actually allows me to boot
into Vista and gives me a desktop but clearly this means I have no display
driver running and have no more than basic display functionality.
I really need help. My own view is Windows update partially installed a
driver or partially updated the driver that was on my system prior to August
27th. Somehow it never completed that operation and my system has residual
registry entries that point to incorrect driver files.
I have tried sweeping registry and I did find residual NVidia files but they
were minimal and when I installed driver again I had the same nvlddmkm.sts
I have two monitors one a Sony 17” LCD VGA and an LG 22” DVI. They were both
working fine prior but now they don’t, obviously. I have seen messages about
dual displays and the drivers/registry becoming confused. So I tried various
configurations of monitor - VGA only, DVI only, connected to different ports
etc. Each time same error BSOD nvlddmkm.sys 116.
It's now three weeks since this happened and my system is still farquhared.
I need some serious help, I am way behind on some lucrative projects and I
might pay for help to get this resolved. Help!!!
