Hello: New to this forum and a bit of a newbie to forums, so please indulge me.
Need help resolving "display driver atikmdag stopped responding and has successfully recovered" issue associated with black screen.
Platform: 4-month old Dell XPS 420 with Quadcore chipset, 4 GB RAM, running Vista Ultimate SP1 (32bit) and an ATI Radeon HD 3450 video card. No gaming software, no TV tuner, no dual monitor; just basic productivity software and a 20" flat panel widescreen monitor.
~4 weeks ago, out of the "blue", experienced a series of random "blue screens" after which the OS typically rebooted on its own (error code 4e in the Windows problem history).
Initial troubleshoot w/Dell: "bad hardware", so they replaced the MoBo memory under warranty. No problems for 3 weeks.
~5 days ago, another blue screen, same error message. This time, extensive t-shooting w/Dell (Windows debugger, etc): "bad hardware or drivers, perhaps bad memory on video card". So, we uninstalled the OEM version of the video drivers and installed a newer one (turns out, I now know, this was NOT the *most current* version, as there's an even newer version on the ATI site) AND they sent out a tech to replace the video card (3 days ago).
Since then, I now no longer have "blue screen" OS crashes, but *black screen* video display crashes (error code 117 in the Windows problem history) and the error message: "Display driver atikmdag has stopped responding and has successfully recovered". Windows diagnostics ran OK, no problems detected (FWIW).
Dell is clueless -- they most recently claimed today that my OS/registry must be "corrupted" (after THEY blundered through the driver uninstall/reinstall) and that I should reinstall the OS (losing countless more hours of productivity, inconvenience), even though there's every indication this is the video card/drivers, not an OS issue.
Since reinstalling the OS just didn't seem right, I've researched this on my own, finding my way to your forum.
I've learned that this is a COMMON issue between Vista and ATI drivers.
I've learned that MS blames ATI and ATI blames MS.
I've seen a host of proposed causes and (more importantly) a host of proposed fixes and solutions.
I also see that there's an even newer driver version on the ATI website.
This seems to happen most predictably soon after system start/reboot, even with only my browser open (no gaming, no videos, etc). It's intermittent, but annoying. I've already wasted countless hours with Dell, even with their live screen-share, "premium" tech support.
Aside from reinstalling the OS (which seems pretty clearly will NOT fix the problem), what has worked for you?????
Thanks so much!!
EDIT: I forgot to mention, if there's already a thread on this, please forgive me and please direct me to it (I'm a bit of a geezer on these forums :sigh
