igdkmd64/i3 540 crashing widows 7 x64, no bsod but occastionally a .dmp file

[idata]

I am getting a crash when playing video, particularly full screen video, on my i3 540 HTPC. Usually there is no .dmp file, but I have gotten 3 of them from the daily crashes in LiveKernelReports. The problem is semi-intermittent, but nearly exclusively happens when playing video. Out of the 50 or so crashes, 1 of them happened at desktop.

When playing the video, the system will freeze. The display will present with ~14 columns, alternating between clean display and garbled. The garbled columns appear like stacked = signs, about 20px high each, with alternating garbage and clean display (iirc.). Anyway, it always presents the same way, leading me to believe it is a video issue. Also, on reboot the machine needs to get through post with video off, then rebooted again to get video out to work. This issue is the same using dvi=>hdmi or hdmi, but hdmi is even touchier.

All drivers are up to date already, by manual inspection and according to the intel software update scanning tool. The latest video is 2104, which I have. Chipset & video bios are all current. Bios is flashed to latest. All the basic bases have been covered.

I doubt it is a heat issue, since I can:

1. Run 4 threads of distrubited.net (max 100% on both cores, as well as the 2 fake HT cores)
2. Run http://www.ozone3d.net/benchmarks/fur/ FurMark at the same time, stressing the GPU directly
3. Do this for 24 hours, in the same enviroment
4. Voltages all look fine, no spikes or drops according to HW monitor and several other monitoring tools.

The 3 minidumps all point to igdkmd64.sys. I have them to attach, but can not in this forum software. They look sorta like this, but this is from the previous (2086 build) if I am not mistaken. I have not had a crash produce a .dmp file since then, it usually goes down too fast.

Probably caused by : igdkmd64.sys ( igdkmd64+1cc60 )

Got a blue screen finally, rather than an instant reboot. I am also getting reboots as soon as the shell starts up, also instant, but this time I actually got a dmp file.

Intel really doesn't care. I have actually had to recommend AMD since this happened, or at a bare mimimum go in aware that the GPU should not be used and you MUST by a discreet card.

So far the support responses have been:

* buy a separate graphics card

* ask your MB manufacturer for *custom* drivers! (this is really, staggeringly, soul crushingly idiotic)

*

My only conclusion is that the integrated graphics/drivers do not work. Intel knows this, and won't fix it. If there is some help out there, I can't find it.
