Hi,

I just got an iBuyPower CZ-27(GT70) laptop with a 780m today with all the drivers preinstalled. The first thing I did was to try and open the NVIDIA control panel to try to set some settings. A message box came up saying NVIDIA display settings weren't available. I'm like ok, maybe I need to be playing a game first so it switches graphics cards since its probably running on the Intel HD 4600 graphics right now. I open up Bioshock Infinite to see if it would fix the problem, but the control panel still wouldn't open. Not only that, it was still using the Intel HD 4600. I tested with League of Legends and I got 30 fps only on high settings with only the shadows being set to low.

I then open up my device manager and go to display adapters, while running a game, and I see the Intel HD Graphics 4600 along with GeForce GTX780m with a yellow warning sign. I tried tinkering further with it to no avail, and in the end I decided to reinstall windows 8 as a last resort.

Once I finished reinstalling windows 8, I tried reinstalling all the drivers that came on the cd. One driver couldn't install though, which were the NVIDIA ones. It kept saying that it couldn't detect the hardware so it wouldn't install. I went to device manager, and under display adapters, there was only Intel HD Graphics 4600 under it. I then tried to disable that to see if it would work; once I disabled it, a second thing came up which was Microsoft Basic Display Adapter with a the yellow exclamation warning. I tried to install the NVIDIA drivers after, and it worked. After restarting, I tried to open the NVIDIA control panel again, and a message box comes up saying NVIDIA display settings not available, You are not currently using a display attached to a NVIDIA gpu. I go to device manager and still see Microsoft Display Adapter.
(EDIT - I right click and it says Code 31.)
(EDIT2 - I disabled Windows Driver Signing. It changed to Geforce GTX 780M. I installed my drivers again and restarted, now it has disappeared from Display Adapters in my device manager.)

This is the point I got up to and now I'm stuck with what to do next. Please help.

Got the Msi Ge70 with the Intel HD Grphics 4600 and nVidia gForce 765m graphics cards. i have the same problem as above. how ever if i have the intel card enabled through device maneger it just says that its using the intel card, if i disable the intel card though it just switches to Windows Basic Display Driver. getting rather frustrated with this as i have tried working out this problem for some time now.
Hope someone have a really great advise of what the problem could be.

I just went through a difficult process trying to figure this out with an Origin PC. The GTX 780M would be recognized for a while after rebooting or putting the machine to sleep and awakening it. Then the screen would flash, and when I looked at the Device Manager, only the Intel HD 4600 was working. A Microsoft Basic Display Adapter was added but not functioning properly.

Origin really tried. They sent me a new graphics card, which had the same problem. I sent in the PC. They found some problems and sent it back. It took the card much longer to "fail" as above, but it still did.

Calling them again, the tech tried disabling the EVGA Precision X overclocking software. That solved it. I'm not sure, but I think the problem started with the installation of Windows 8.1 soon after I purchased the PC. In any event, I don't need graphics card overclocking and certainly wish I had never ordered it. After two months of dealing with this, I don't even want to try to get it to work. If you want to see if this is your problem, open the EVGA software and uncheck the box that says it should run at startup. Reboot and see how you do. In my case, even the fans are running 90% quieter now. Apparently overclocking with EVGA Precision X, even on an idle PC, can create more demand on the card than it can manage. The odd part is that it had taken it as much as six hours to fail (but did so religiously every day) after the repair shipment to Origin. I'm guessing they adjusted the software but still didn't recognize it as the culprit.

One other note: Even if EVGA is set not to allow overclocking the GPU, check out Task Manager and the amount of CPU strain it creates just by monitoring the GPU. In my case, four separate instances of EVGA were open to manage the GPU all the time, and consumed a total of 65% of a mammoth processor's resources. Keeping it from running at startup improved the PC's performance (and quietness) measurably.

My take-home lesson is that if you really need overclocking, be prepared to manage it carefully. If not, stay far, far away.
