Installing Nvidia 266.58 on XPS 15 with GT 420M

I've received a new XPS 15 this week. Since updating Windows 7 I have seen a problem running Flash on the Nvidia GT 420M; flickering graphics. This is most noticable when running BBC iPlayer in full screen mode. I have seen other reports on the web that state that the latest Nvidia drivers (266.58) fix this problem. I have read on this forum about people who have successfully installed this driver. However when I try and install the driver (downloaded fom Nvidia) I get a message 'The grahpics driver could not find compatible graphics hardware'.

Does anyone know how I can get around this problem?

 

The only drivers that will work are from the Dell website since they are Optimus compatible drivers. However, Dell is usually slow at updating them compared to the nVidia website.

 

Actually, theres an NVidia beta driver running around that support optimus. I know because im using it.

somebody else posted it a few weeks ago, just search for it

 

I didn't have a no problem installing the 266.58 on my xps 14 with GT 420M

 

Me neither! Make sure you have the Dell driver installed and working and then install the new NVIDIA driver over it, don't uninstall the Dell one first!

 

Thanks for all the suggestions. And apologies are in order.

It turns out I've been a bit of an idiot.
Somehow I manged to download the desktop version of the drivers. I've now downloaded the notebook version and the installation went smoothly. And it has fixed the Flash problem.

 

I downloaded the 266.58, and it did not work on my XPS 15/420m...I had to roll back to the dell.com drivers. (my comp would freeze anytime it initiated the nvidia gpu). You actually got these drivers to work?

 

Did you get it from this link?
NVIDIA DRIVERS 266.58 WHQL

I uninstalled the dell nvidia driver before installing the new one

 

^^ I have installed that....
NO issues... Its great... I got a slight performace boost too..
Now i can run Dead Space 2 Maxed out at 1366x768 with stock getting 40fps avg

 

arg, still didn't work. Keeps locking up whenever the NVIDIA GPU is in use. Do you guys have the Optimus version?

 

You sure you're not downloading and installing the desktop version?

 

I installed that driver from nvidia no problems. Took less than 5 minutes and the extra performance was amazing. I'm oc'd to 730/960 and can play black ops with no lag whatsoever now. With the dell drivers, it acted like crap. I did have, and still have optimus after installing the updated drivers from nvidia. I have the i5 560 and GT 420M.

 

^^Yup...
Just goto nvidia site and download NOTEBOOK drivers ....
That should do

 

I was able to install the 266.58 drivers without issue also. I haven't really pushed the GT too much, mine currently runs at 650/850 which gives me what I need to play Rift well.

 

Okay, now I have these drivers installed (my problem before was that there were multiple drivers installed which i uninstalled through programs features rather than device manager). Anyways, these for sure work, as i am able to watch a video downloaded to my computer, but it will not display flash video with the nvidia GPU. It either shows a black screen, or if i try to go full screen, it crashes my computer. Have any of you had this problem?

 

Ok, so this gets weirder. I installed the flash 64 bit plug-in, and now i have flash working in Internet Explorer, which is great, but still the same old problem in Chrome. Any ideas why this might be and how i can fix it?

 

Chrome does not support adobe and has it's own flash stuff, that's AFAIK. I'm also using chrome, though there's no problem.

 

This is a problem the new flash 10.2 has with the nvdia drivers. I got the same problem. No solution so far.
