BSoD caused by nvlddmkm.sys
Hello everyone. First of all, I apologize for any possible misspellings/mistakes, English is not my mother tongue.
I've been having an issue with the "nvlddmkm.sys" driver for about 3 months now. The thing is that it started all of a sudden, when the screensaver started playing back then. It seemed to freeze the laptop and then it restarted, showing a "double screen" and a lot of vertical pink/green lines all along both screens. Even the resolution quality seemed way lower. It was something that could be fixed by shutting the laptop down and turning it on again or just by restarting it but, one day, it just showed that issue everytime. I took it to a technician who couldn't find the problem and I just kept using the laptop as usual. When I turn it on, most of times, it does the "double screen and lines" thing but some other times it works normally, as if nothing was wrong. When it works properly, sometimes it crashes down. That's how I got to finally notice (not long ago) what the problem was: An issue with the nvlddmkm.sys file as it finally displayed a BSoD and I got to see the System failure details. I've been searching for help in different forums with no luck. I've seen there's a way to fix it but many people say it doesn't work (the "download another nvlddmkm.sys file, rename the older one and replace with the new one" thing). I haven't tried it because I'm afraid of making a mistake and not being able to use the laptop anymore ^^; That's why I tried asking of possible solutions and it's effects before doing something wrong.
I'm attaching the .rar archive from the SF tool.
As additional info:
The laptop with the issue is a Dell Inspiron 1420
My OS is Windows 7 Home Premium 32-bits
Processor: Intel Core 2 Duo
CPU T7250
2.00GHz 2.00GHz
RAM memory: 1.00GB
GPU: NVIDIA GeForce 8400M GS
BIOS Video version: 60.86.45.00.10
Driver version: 185.85
I have a question: What are the normal/common temperatures for this kind of laptops? And for that specific GPU?
Any help will be appreciated
