One Way to fix Nvlddmkm.sys Windows Vista Problem!

Various websites and a potential class action law suit talk about the problem of using the 8800 Series GPU with Vista. When running DreamScene, DirectX 10.0 demos, and video DVD's, a message pops up after a couple of seconds of a blank screen saying that Nvlddmkm.dll or Nvlddmkm.sys has lost connectivity and has been restored. In most cases the computer has to be rebooted to permanently stop the error once it has occurred even AFTER the offending program (such as DreamScene) has been stopped. In some cases, there is a BSOD pointing to Nvlddmkm.sys or some other error message, which requires a hard boot.

Many solutions, including driver updates, elimination of older versions of the drivers, BIOS changes, and removal of Creative X-Fi drivers have been suggested in hundreds of blogs. None of them work in isolation for long. The most promising solution, the elimination of older Nvidia drivers lurking around in Vista has been acknowledged by Nvidia and they have introduced a new installation program/driver in their 158.15 release of April 12. This did not work to completely alleviate the problem.

Well, for me, I have fixed the problem; I simply installed 158.15 which slowed down the recurrence of the problem but definitely did not alleviate it, and then later, as part of my two month quest to solve this problem, as an experiment, turned off UAC. Everything has been running fine for 2 days including DreamScene, which is a record; DreamScene had not run for more than 5 minutes prior to this last step. I had never before been able to run the DirectX 10.0 demos that are downloadable from http://www.nzone.com/object/nzone_cascades_downloads.html which is now astounding me with its beauty and stability. I urge you to test this (less than perfect) solution or to get Nvidia to test it. I have “replied” to many of the blogs that I found about this subject and offered this solution; one person has responded telling me that it had fixed his problem too and one person had always had UAC turned off and AFTERWARDS installed the new drivers and nothing changed for him. It certainly would be beneficial, if this is "the" solution, to get the word to Microsoft and to Nvidia. Though I have gone on those websites to report my finding, I am not sure that it will be seen by enough people to give Microsoft and Nvidia an incentive to test. We al;so need some active participants to these blogs to carefully track down differences in setup that may affect this SERIOUS problem.

I have to say that I had this problem and this fix helped me out greatly when trying to fix my rig.

Why is Windows closing my program?

Windows might close a program and then notify you if it determines that the program is either a security risk or incompatible with this version of Windows.

When Windows closes a program because of a security risk, it is because some programs might use your computer's random access memory (RAM) in a way that could be exploited by a virus and harm your computer. Data Execution Prevention (DEP), a security feature of Windows, tracks how programs use memory. If DEP finds memory being used incorrectly, DEP will close the program and let you know. If you trust the program, you can add it to an exceptions list so that DEP won't close it, but you should first check with the manufacturer of the program to see if there is an updated, DEP-compatible version available.

When Windows closes a program because of compatibility issues, it is because some programs could damage Windows if you try to run them. If Windows notices that an incompatible program might harm your computer (for example, by damaging important system files), Windows will close the program and notify you. Check with the manufacturer of the program to see if an update is available, or check Problem Reports and Solutions in Control Panel to see if a fix from Microsoft is available.

	• Open Problem Reports and Solutions by clicking the Start button , clicking Control Panel, clicking System and Maintenance, and then clicking Problem Reports and Solutions.

Now I would have to say that this official statement is kinda flaky in how they word it. Alot of time programs fail in vista is due to ad coding or bad compatibility with vista itself.

How to make firefox faster! Simple to use changes to help speed it up!

1.Type “about:config”. Into your address bar at the top of the screen. If there is a prompt just click past it. Now looking at the page You should see a long list of words on the left side. Find these phrases.

network.http.pipelining

network.http.proxy.pipelining

network.http.pipelining.maxrequests

Usually Firefox will make one request to a web page at a time. When you turn on pipelining it will connect many times at once, which will really speed up your pages loading!

2. Alter the entries as follows:

Set “network.http.pipelining” to “true”

Set “network.http.proxy.pipelining” to “true”

Set “network.http.pipelining.maxrequests” to some number between 25-35, I personally use 30. This means if you my settings, it will make 30 requests at once.

3. Lastly right-click in the long list window and select New-> Integer. Name it “nglayout.initialpaint.delay” and set its value to “0″. This value is the amount of time the browser waits before it acts on information it receives.

If you’re using a broadband connection you should REALLY see a big boost in speed!
