Other possibilities for my display 'stopped responding and has
successfully recovered'
First off...I don't expect most of the folks on the thread
to read this, just the few that find this sort of troubleshooting especially interesting.
So, poking around with system information I find something
strange, this list of IRQ numbers, it ranges from 0 to 190,
with two exceptions:
IRQ 4294967294 Broadcom NetLink (TM) Gigabit Ethernet
IRQ 4294967293 Intel(R) HD Graphics
System information gives all IRQs' an "OK", but the fact
that the number is so high sure makes me wonder.
My hardware devices...
I have one unknown device marked with an exclamation point
in my device manager, this is all that shows, no other
identifying information--and no drivers are installed for
this device.
PCI\VEN_8086&DEV_3B64&SUBSYS_04381028&REV_06
PCI\VEN_8086&DEV_3B64&SUBSYS_04381028
PCI\VEN_8086&DEV_3B64&CC_078000
PCI\VEN_8086&DEV_3B64&CC_0780
I think this has to do with Intel AMT, and
for good or ill, I've uninstalled anything
I could find to do with it hoping this might
clear up my display failures. I'm not even sure
I would want this sort of pathway into my PC!

That said, I thought I might run this thing...
Unknown device identifier, to see for sure.

Now, getting to actual drivers, among the many video device drivers for my Intel HD (I have the Pentium G6950 with
integrated graphics) I see this one standing out from the
other file names
c:\Windows\system32\difx64.exe
google searches suggest it too might be something
for Intel AMT. !!!
One driver I'm certain is essential, and that System Information
reports as being the biggie happens to be this one
c:\Windows\system32\DRIVERS\igdkmd64.sys
I have the latest one I think
(8.15.10.2119, 9.85 MB (10,326,784 bytes), 4/21/2010 6:18 PM)
Finally, there is one more driver that looks interesting
when I google around for it...
c:\Windows\system32\IGFXDEVLib.dll
google found...
Intel(R) integrated graphics controller
Startup Type: This program uses the
Winlogon Notify key to automatically start.
This key is used to run certain programs when
specific actions occur such as computer
starting up, a user logging in or logging
off, or a computer shutting down.
Once again, we are sort of in this area of sleep mode
and such.
Whew, that is all for now--any thoughts are much appreciated! |
