Been encountering a very strange issue of late. We been using Intel DQ67OW Boards for the last few months pretty much without issue until our latest batch where we are now seeing the machines Randomly Restart without Bluescreens and the only error in the Event Log is a Kernel power error telling us that the machine restarted unexpectedly.
The only promenant change I can see is the BIOS Version which on our new batch of machines came in with BIOS 51. I have since upgraded and tested BIOS Version 52 with no change.
I am unable to force the issue to occur it just decides to restart without any sort of provocation.
Have any of you seen this happen before?? If so could you let me know if you have come across a workaround or a solution.
I've gotten what I believe to be a workaround. If you disable EIST and C-State's in the BIOS the system seems to become stable. I can't say that this is actually a fix or a proper workarond. All I can say is that the PC's haven't so much as twitched since I changed those settings.
If anyone else runs into a similar issue can you try this and let me know if you get the same results as me.
I am having exactly the same issue.
I first noticed this issue when I used the default Intel driver install from the CD that came with the board. The problem was severe, the entire screen would flicker to black and come back. After a few times doing this, the system would reboot within 30 seconds of coming up. I know the memory is good, as I had used it on a prior system for some time and know it was stable (I upgraded that system to 8gb and took the 4gb and stuck it in this system immediately prior and that system, a Intel PW55B was perfectly fine)
I have installed the latest BIOS and video drivers with and it decreased the frequency of the reboots, from immediate every time within 30 seconds, to randomly every few minutes to an hour where the screen has a dark diagonal line about 1" wide goes across the whole screen left to right at a slight 20 degree angle.
This problem does not occur at all in SAFE mode at all, which tends to lead me to believe it is software related. Not one flicker or reboot while I am using the problem computer to type this.
