I have an Asus Zenbook Prime UX31A with a Core i7 3517U CPU and Intel HD Graphics 4000 running Windows 7 Ultimate 64 bit Service Pack 1, with all current updates installed. I have been experiencing what appears to be an intermittent loss of sync on the display, which completely scrambles the image. The only way to clear the issue is to reboot the system, after which it is always fine. This would seem to suggest a software/driver problem. There is no correlation with a particular task or app, idle time, suspend/resume (though it never does this coming out of resume), operating temperature, or the amount of time the system has been on. It can run fine for weeks or have multiple occurrences within one week.
I updated the original graphics driver from 2012 with the current Intel driver available from Asus which is 10.18.10.3412 dated 1/22/2014. The Intel Driver Update Utility would not allow the installation of any drivers from the Intel site since Asus has evidently modified the driver for this system. I'm at a loss as to what to do next. Any assistance would be greatly appreciated.

Hello, hij2001:
Thank you for the information provided.
I would like you to test the behavior of the system in the following scenario.
Please access the BIOS and leave the computer there until you get the scrambled display, if this happens, the BIOS is at a pre-os level which means that no drivers are loaded.
By doing this, we could find out if the issue is the screen or not.
I insist on this because different drivers from different providers have been tested, as per your answers so far, so we can find out the source of the possible issue I am recommending this test.
Regards,
Esteban C

I'm willing to give this a try, but since the failure is so intermittent, the best I could do would be to try it overnight a few times. The problem is that there is no guarantee that it will fail as it has been fine running overnight in the past.
While this test will eliminate the drivers (which by virtue of it failing across multiple drivers and OSs, I think we already have), I don't believe that this would determine whether it is the screen (which I personally doubt), silicon, or other HW failure. Nevertheless, I'll try it a few times and let you know the results.
Regards,

I've left this in the BIOS screen for 6-8 hours per night, and a continuous 16 hour stretch over the weekend with no failure. I'm not sure that this has proven anything since the problem is intermittent in nature and I can go several days without a failure. It's also not clear to me that if there was a failure, you could determine whether it was the chipset, motherboard or display. I'd be interested in your rationale for this determination.
Per my earlier responses, the fact that this has persisted across both Win 7 and Win 10, and multiple versions of drivers would seem to suggest hardware, and the combination of the loss of sync and motorboating audio would seem to eliminate the display in favor of the other two hardware elements.
How would you like to proceed?
Thanks and regards,
Howard
Hello, hij2001:
In this case if possible, request an RMA for your product.
Since the problem is not easy to replicate, it is difficult to troubleshoot it.
It could be a hardware issue that would be one of the options.
If this is a boxed desktop processors, you could add this thread in the RMA request with Intel Customer Support: http://www.intel.com/content/www/us/en/support/contact-support.html Contact Support

This system is well out of warranty, and doing so would cost $50 to diagnose, and $500 for a new motherboard (which would be the "repair"), and another $10 for return shipping. Clearly not worth the money. Since Asus support claims that this is not a problem they are seeing despite several support forums with similar issues, I will simply live with this until it either creates a hard failure, or the frequency of failure becomes unbearable, at which time I will replace the system.
Thanks for your troubleshooting suggestions.
Regards,
Howard
