Multiple copies of Video drivers-what to do?

I have win 7 home prem 64 bit on a Samsung Gamer Series notebook. No problems for months. Didn't even need to restart ever except after updates. About 1-2 months ago, installed Nvidia Experience, but haven't loaded any games yet. Installed Steam 7-3, but haven't installed any Steam games either.

The most recent change was letting Nvidia Experience install driver updates, but no Betas. 2-3 driver updates in last 1-2 months. Just had latest update from GeForce 320.18 drivers to GeForce to 320.49 a couple days ago. That update also updates / Installs PhysX System Software 9.13.0604. And
Installs HD Audio v1.3.24.2

Seems like troubles started then, but I've also had about 16 Wordpad documents and 25 Firefox sessions open at a time while doing some financial research papers. Don't know if it's a coincidence or not, but when running WMP, seems like switching from Dual View to just the notebook display used to make everything wonky for 5 seconds, but then it would be ok. Now, I get a loud rattle and then no sound until I close and re-open WMP.

Firefox has also crashed w error 41 several times in last few days.

Mouse starts to intermittently stutter, then stops regularly for 5-10 seconds, then freezes. and CTRL Alt DLT doesn't do anything. Have to hard boot.

System Specs below & SF attached.

Any ideas or anything obvious in the report?

Thanks!

Samsung notebook. Gtx 675m graphics. On about 7-10, I had crashes and submitted an SF file for help. Thread is here:

Here's what I got for a response:

OK, so I uninstalled the Drivers from the Nvidia site, since they were apparently causing the issues. I called Samsung to ask if they have any updated drivers. Their last release was 02-2012, which was a few months before I bought this notebook new. They said the one on their site is the only officially supported one, but there are many different updated versions on the Nvidia site which should work for me.

I never tried any game play on the stock Samsung driver, because I replaced the C drive with an SSD right when I received it. I then did a clean install of Win 7 home prem 64 bit. So then I went to the Nvidia site and tried the "Nvidia Experience" program which auto-downloads drivers and settings for games.

I recently deleted the "Nvidia Experience" and the Nvidia driver which was causing the issues. So now I'm at a point where I want to start playing games. I installed the stock driver from Samsung. If I don't like it, I'll try a different Nvidia driver than the one I previously had installed.

After I installed the stock driver, out of curiosity, I did a search for the file which was causing the issue to see if it is in the Samsung driver also. I got 4 results for the same exact file name, nvlddmkm.sys. The dates "created, "modified", and "accessed" are different on two sets, and they are in different folders also.

Before I start loading games, I'd like to know if having multiple versions of the same file name in separate folders is going to become an issue, or if I should just let them be. I haven't done any gaming on it yet, but I've had zero errors related to the drivers since installing the stock driver. Do I "NEED" all of these files, or should I delete one or more? If so, which ones should I keep/delete?

Here's notes and snips for each one.

These top two seem identical except for the locations. They were both "created" July 18th 2013, which is about the date I installed the stock Samsung drivers. Plus, the dates last "Modified" are 02/2012, which matches the date of the latest updated driver on the Samsung site.

C:\Windows\System32\drivers\nvlddmkm.sys

and

C:\Windows\System32\DriverStore\FileRepository\nv_lh.inf_amd64_neutral_bc69f20e3115af59\nvlddmkm.sys



C:\Windows\winsxs\amd64_nv_lh.inf_31bf3856ad364e35_6.1.7600.16385_none_4a5c7d78e486512b\nvlddmkm.sys

and

C:\Windows\System32\DriverStore\FileRepository\nv_lh.inf_amd64_neutral_bc69f20e3115af59

These two also seem identical but in separate folders
ALL dates for these two files are during 2009 are during 2009. Notebook was
bought new 6/2012. Plus, size of these two files are smaller than the two above.

If this is any help, this is the last error message I got back before uninstalling the new driver and installing the older one.

Hi Arc,

I thank you for your advice regarding the multiple files of "nvlddmkm.sys" .

I definitely will mark both your post and the one replied to by Northernsoul55
as solved(Hopefully it WILL be solved). I didn't mark the 1st post as solved because I didn't follow his instructions until I had time to do so, some days later.

I usually have no problem uploading snips to my posts, but that morning when I clicked on browse, it did nothing. I tried opening a new session of Firefox, restarting my computer, starting a new thread and trying again, but every time I would click to browse it did nothing. So today I just tested it before sending this reply, and it went smooth as silk.

https://www.sevenforums.com/drivers/2...load-test.html

So I don't know what the issue was, but it's working now. Thanks for that link. It did show me a couple options I was not aware of.


Did you want me to upload the MSINFO zip into a reply to this thread, or somewhere else? As a new post in "BSOD" or "Drivers"?

I've spent a lot of hours getting my notebook system to the point where I'm not getting errors constantly. Some were probably caused by me changing things based on advice from others, so before I do this, can you explain if having these multiple instances of "nvlddmkm.sys" is a potential problem, and if so, how the MSINFO file will be used, and by whom? I'm cautious about uploading system info. I've uploaded SF files before, but never MSINFO.

Thanks for your time and I'll get that ready to upload while I await your response.

Eddie

Hi Northernsoul55,

Thanks again for your suggestions re this post: https://www.sevenforums.com/bsod-help...ml#post2458625

Seems to be much better now, with one issue I've noticed. I posted a thread on it here:

Multiple copies of Video drivers-what to do?


arc has replied and I'm waiting for him to reply again re where to post the MSINFO file.

Thought I'd keep you in the loop and I will mark both your posts as solved when we're done.

Thanks again,

Eddie

Sounds good,

Do I just post the MSINFO in my reply, or somewhere else?

I searched for "Merge posts" and nothing found. Do you have a link or instructions?

Thanks,

Eddie
