I've been battling BSOD for a month now and have reinstalled Vista 3 times. I am still getting BSOD with a 116 error code indicating nvlddmkm.sys. I can boot into Safe Mode and I can boot Vista with the nVidia graphics driver disabled. When I get the option to check for solutions (after going into Safe Mode following the crash), I get a message that the nvidia driver has failed. I tried downloading the newest driver from nVidia's website, but I'm still getting BSOD. I have run diagnostic tests on the hard drive, CPU, memory and motherboard and it passes all these tests. I did try running a diagnostics test on the graphics card twice (with the driver enabled) and it crashed the system both times.
So, I think the card is shot since I'm still getting BSOD with the newest drivers. I'm fine with replacing the card if it will save my computer, but I don't want to spend the $$ if something else is wrong with my computer. Are there any other tests I should run on the computer before buying a new card? Also, what card should I get. I have an HP m9150f with a Nvidia 8500 GeForce card. Also, I have not downloaded the Service Packs or updates from Windows (I did the first 2 times I re-installed and the system was still crashing). Should I install them right now or will that just complicate things until I get the graphics card figured out?
