Studio 1537 with Intel GMA 4500MHD graphics corruption

Why has Dell stopped offering the Studio 1537 with integrated Intel GMA 4500MHD graphics? Is there a technical problem with it? I have one that was purchased in November '08, and I am having problems with graphics corruption, apparently when an app is using Direct3D, when any of the four newest Intel driver packages is installed (two from Dell Downloads and two more recent from Intel Downloads -- the latest dated Dec '08). Only an old driver v7.15.10.1508 dated June 20, 2008 that came on the Dell Drivers CD seems to work okay on my system, even on a freshly installed Vista Premium SP1 on an external eSATA drive with just the necessary drivers installed in the sequence specified in Dell Article ID 296410. There have been lots of important fixes to the driver since June, but every newer version I've tried has severe intermittent graphics corruption with some apps (probably using Direct 3d) on my Studio 1537 (see cropped screen captures below)

I know there are revisions to chipsets as well as drivers. Is Dell waiting for a revision of the GM45 chipset before they start offering the GMA 4500MHD graphics again in the Studio 1537? Or are all the recent drivers defective? Or does my Studio 1537 have a unique defect?





Another strange characteristic of the malfunctioning drivers is that the Vista Performance Information control panel reports a lower graphics performance score with the newer drivers, down from 3.8 on the works okay driver to 3.4 to even 3.1 with the most recent. What's going on?!?

As far as I can tell, Intel doesn't provide a way on their web site for end-users to report problems with these drivers, or to ask a question. Does anyone know of a way to contact Intel about this?

I'm eager to get my Studio 1537 repaired, but I'm frustrated that I don't know how to proceed.

If you want to try to reproduce the problem, see my instructions in my post at the Dell Community Forum: http://en.community.dell.com/forums/t...

Thanks, if you can help,
