   I have an Acer Aspire 8920G - 834G32Bn with NVIDIA GEForce 9500M GS running Vista HP 32bit.

   I recently noticed a performance issue flagged by Vista in the Performance Information and Tools->Advanced Tools window. It indicated that nvlddmkm.sys (NVIDIA compatible Windows Vista Kernel Mode driver) was interfering with Windows resuming from sleep mode.

   I then updated the NVIDIA driver to the latest version 7.15.11.7561 from the Acer Web site.

   The performance issue still remains. However, I noticed that the Vista WEI score for Gaming Graphics dropped from 5.3 to 5.2. Wot's... uh the deal?

   Also, I see a new driver - Notebook Release 186.81 WHQL on the NVIDIA Web site. Has anyone tried it? Is it OK to give it a shot?

   Any idea about the nvlddmkm.sys problem?

   Googled and found people have bigger problems with it than just a performance warning. BSOD is as big as they come. Fortunately for me, it's not come to that. Not yet?

   On my 8920G, I ran the NVIDIA 186.81 drivers under Vista and am now using them under Windows 7. The version is 8.16.11.8681. So I don't think you should have a problem.

   I can't recall the rating under Vista, but under Windows 7, my '3D business and gaming graphics performance' score is 5.7. Unfortunately, the 'Desktop performance for Windows Aero' score is 4.5, which becomes the final score. I haven't yet found a way to improve this yet but it doesn't seem to cause a limitation in normal use.

   Ensure that you have ALL of your updates for Vista. There are updates available that should resolve the "sleep" issue.

   I think Peter may have got out of step with his answers. His answer in another thread stated that Nvidia provide support for their drivers.

   Since I recently got an answer from Acer support that they don't support software, only hardware, I'd think you could quite happily install the official Nvidia drivers. As I've said, I've had no problem with them.

   Sleep mode can be affected by the graphics card driver and it's interaction with the OS. There are documented cases of both an implementation in the OS and or the graphics card driver that results in sleep mode not working properly. In most cases people that I have seen most people are not up to date with their operating system updates as the vast majority of video card drivers for Vista are by in large bug free over the last year and a half.

   Sorry about the late response.

   My Vista OS 32bit HP is indeed up to date. I'm stumped because the issue was supposed to have been fixed by Microsoft as back as Vista SP1. I've even tried the latest nVIDIA driver - 8.17.11.9562. I installed a USB printer yesterday and it seems that this device is also interfering with Windows resume from sleep.

   No crashes yet though.

   I checked a HP Pavilion notebook running Vista HP (also up to date) but indicates the same performance warning.

   I could always perform a system restore but shudder at the thought of zillions (exaggeration) of apps I use that would have to be reinstalled. Thanks.
