Well it looks like your only option is to test some of the beta driver here: http://forums.laptopvideo2go.com/forum/159-19x-series-geforce-driver-releases/ I'm not sure if you've done this before. Just remember to download the modded INF file with each driver and replace with the one in the drivers files you download and read the posters comments for solutions before you try a driver.
Also you might wanna check out this link: http://xpsm1730.blogspot.com/2009/03/updating-your-video-driver-right-way.html for the right way to update nvidia drivers. You might have some older nvidia files that are messing things up.
On an unrelated note, today I checked out some of the windows 7 "optional" updates available for my laptop and I noticed a bunch of driver updates. After installation, it got rid of 2 out of 3 unidentified base system devices! I'm guessing the last one has something to do with dell media direct.
I have been contemplating upgrading to Windows 7 on my M1730 with the 8800m GTX card but not finding much good news out there in regards to this upgrade. From what I have found on Nvidia's site is the 8800M series is NOT supported at this time in Windows 7. If you go to this page http://www.nvidia.com/object/io_1241025430517.html on Nvidia's site you will see the 8800M series is not listed. Not sure why but I have also tried to contact Dell in regards to this and they give no answer as to why. I hope they fix this but I have to say as of right now I don't have my hopes up. Totally confused as to why this one card isn't being supported at this point in time.
It looks like dell is working on windows 7 drivers for M1730 and they should be up in the next 2 weeks or so. I guess it's taking them longer than the other xps laptops because there are problems with the 8800m gtx drivers. My 8700m sli drivers run fine on windows 7.
Dell replaced my M1730 in June of this year and the replacement, per invoice, has the 1GB nVidia SLI GeForce 8800M GTX. In the device manager the cards shows up as 2 9800M GT. I have installed the 186.81 driver in Windows 7 32-bit and it seems to be working just fine. I had a little bit of a problem getting the right driver for the PhysX but eventually I donwloaded the right one and now everything works. Wonder why my video card shows up AS 9800M? It did that in Vista too.
My original order had nVidia SLI Dual GeForce 8700 GT with 512MB GDDR3. I am assuming the upgraded it.
I just tested it and it's working fine for me. Maybe you need dell quickset or the dell touchpad/pointing stick drivers to make it run? I installed all the drivers I can find for vista 64 bit on win 7 and then did the regular windows update (the optional updates have driver updates, not the critical ones) after which I was left with only one unidentified base system device in the device manager. The ricoh drivers wouldn't fix this through automatic intallation so I updated manually from the device manager and pointed it to the ricoh driver folder and that got me all the drivers I need.
My guess they're waiting for nvidia to release stable 195 drivers for the 8800m gtx. The 186.81 drivers are working well on win7 for my 8700m gt card, but they don't seem to work for the 8800m gtx (from what I read here). The official desktop 195 drivers just came out, so hopefully soon for laptops. The rest of the win7 drivers work easily.
Alright, goobs23 here. I was the one posting about all my video card problems and such. I had a problem this week on Monday where my power light came on and the hard drive clicked, but the computer screen did not turn on. So, after talking to dell for a couple hours they decided to do on-site replacement of my motherboard. I talked to them on Tuesday night and they came Thursday afternoon with a new motherboard. Technician replaces it and still the same problem. The guy then orders me another motherboard and a video card (8800M GTX) for replacement on Friday and they came in less than 24 hours to replace both parts. When the technician came the second time he replaced both a new motherboard and the video card and upon turning it on my hard drive was not recognized. So, he went back to the motherboard I was given the day before with the new graphics card and BAM it works.
So, the main problem was my 8800M GTX being faulty. All that time I spent searching forums and blaming drivers for not working and it was just a bad card. Thanks for all the help that you all gave me in fixing my problem, but in the end it ended up just being a bad card and nothing I had done or not done. As far as all features working with the XPS M1730 and windows 7; I have gotten everything to work properly now.
