In Windows 7, I keep getting an error message that no supported hardware was found. But when I run the widget on nVidia's website, it finds the card without a problem and recommends 186.03...but I can't install it
By the way, this is in a Dell XPS One 24".
i had the same problem and solved it by manually editing the proper INF file. it worked for another member on here as well and he posted a very detailed description of the steps here: I'm just ready to give up
we all have the exact same Dell A2420 with Windows 7 x64 and 9600M GT card.
you will notice i posted an update a couple posts down from the above link. the NVDM.INF file did not work out as well as i had hoped and i started having a minor but annoying issue so i modified and switched to the NVAM.INF file instead. you may not experience any issues depending on the software you have on your machine.
also, it is worth nothing that even though my machine is working almost flawlessly now, i had to tweak a couple things to get it working in tip-top shape. it seems that the display drivers have issues with some of the more advanced power management options, so the best setting is "Performance", not "Balanced", which is set by default. and turn off hibernate and sleep. when my computer goes to sleep, it is 50/50 on whether it will come back or not. sometimes it blue screens and sometimes it just hangs, so i just set it to never sleep. i still have the monitor turn off and the hard drives turn off which seems to work fine.
