I have:
amd athlon 62 x2 3800+ 2.0ghz
3.00 GB ram
windows vista 32bit
nvidia geforce 9600 gso

and my computer crashes whenever i play any game. This only occurred when I went from windows XP to Windows Vista; it was a clean install. ill be able to play a game perfectly for a few seconds and then it will just crash. I'll play a old game like counter-strike on lowest settings and it will still crash. i've also tried underclocking the GPU and placing a huge fan next to my open case and it still crashes. I've had this problem for about a year, in the beginning I tried numerous ways to fix it and then just gave up for like 8 months, until now. From that time, I remember that i got BSODs that had nvlddmkm.sys errors. any help please!

RE: nVidia BSOD nvlddmkm.sys - Depop
I have found and fixed the problem today. This is what appears to happen.
during the installation of the most current drivers 100.65 Vista, an OLD file
nvlddmkm.sys is copied into windows/system32/drivers and not the current one
in the install. As a result the new drivers are attempting to access a file
dated 11/2006 instead of 2/2007 ver 7.15.11.0065 which is in the newest WHQL
driver ver 100.65 vista 32.

Fix: Go to windows/system32/drivers and rename nvlddmkm.sys to
nvlddmkm.sys.old. Go to the nvidia directory and find the file nvlddmkm.sy_
and copy it to windows/system32. Using the cmd window (DOS box) type
EXPAND.EXE nvlddmkm.sy_ nvlddmkm.sys. When the expansion is complete, copy
the new nvlddmkm.sys to windows/system32/drivers and restart the computer.

Your computer should now work properly.

You will notice that any uninstall and reinstall of nvidia drivers will not
remove the old nvlddmkm.sys file and will not overwrite it with the newer
version. You have to do it manually. I do not know why this happens but who
cares as long it is fixed.

this from google

best best is to follow instructions above, download nvidia cleaner and newest driver and start over

problem potentially fixed, not sure from what though. i did the thing suggested with the .old nvlddmkm.sys file and i also removed two sticks of ram (were part of a 2gb ram kit), and i also didnt have a sound driver (sound driver disappears sometimes whenever i restart my computer for some random reason). been playing for a good 20 minutes. going to reinstall sound driver and see where that gets me.
