I have a dell Vostro 3500 which was released early 2010. The windows 10 upgrade app tells me I cannot upgrade to windows 10 because of the NVidia GeForce 310m driver is not compatible.
I also have an inspiron 1545 released late 2008 this can be upgraded to windows 10.
I have looked into this driver issue as I have been running windows 8.1 on the Vostro 3500 laptop for sometime. However the graphics driver sometimes crashes and has to recover. While this is useable it is not ideal.
In order to run windows 8.1 I had to download and install the old XP 64bit driver and run it in compatibility mode and as administrator. This took some effort and messing about to get it to work as well as it does.
However I have tried to install windows 10 preview on the system it will not let me install at all so I cannot even get to the point where I can try the windows XP driver. When I try to install directly on this system.
However I did install windows 10 preview on a different dell laptop the is compatible and them moved the hard drive into the Vostro 3500 to see what would happen.
Windows 10 worked on the laptop except for the GeForce 310m which had a exclamation mark in device manager. and it too sometimes crashed and had to recover
This is telling me the only thing stopping this laptop running windows 10 is the lack of a dell GeForce 310m driver
Will dell be releasing an updated driver for this graphics card as it seams very unfair that one laptop over a year older than the other can upgrade while the newer higher spec one cannot. Just because DELL cannot be bothered to come up with a new driver for windows 8.1 and windows 10
