I have an ASUS U43Jc laptop that came with an Intel HD Graphics card and an NVIDIA GeForce 310M. A couple of days ago I noticed Skyrim running SUPER slow and went to update the NVIDIA driver. Everything seemed to go fine, until NVIDIA just disappeared from the device manager and was replaced with something called "Standard VGA Graphics Adapter". I can't update or roll back the driver because when I try the computer says it doesn't have any NVIDIA hardware.

The thing is, SOMETIMES the card still shows up when I restart. Sometimes it's there for a few seconds before being replaced with "Standard VGA Graphics Adapter", sometimes it's there for an hour, sometimes 20 minutes, sometimes I start up and it's already gone. When I manage to catch it before it runs away, it says it's up to date and the option to roll back the driver is greyed out.

I've tried uninstalling everything NVIDIA related and restarting my computer, I've tried going into BIOS but there are no options related to onboard devices or chipsets or anything mentioned in any other forum I've checked. Please please please help.

First from Nvidia, then (after uninstalling everything Nvidia and restarting) from Asus. So both.

Ok, I think it has something to do with your driver installation issue. There must be an option on your BIOS to select between "integrated graphics" and "GPU", search it carefully.

1. Use Revo Uninstaller, CCleaner, Driver Sweeper, in "safe-mode" to completely uninstall the driver and clean the registry.

2. Enter BIOS and look for the PCI-E setup. If found change it to Nvidia GPU.

3. Restart computer, see in your device manager if the GPU is detected.

4. Then install driver.

Hope it helps.

Alright, I used IOBit uninstaller (my preferred uninstaller), CCleaner, and Driver Fusion. I assure you, I did not see anything like that in BIOS. I restarted, Nvidia was there, I installed the newest driver from the Asus website and installed it, then restarted. Nvidia was still there, but my computer soon blue screened.

So I went into safe mode, swept the driver with all three programs again, restarted and installed the latest driver from the Nvidia website (which is newer than the one on the ASUS site). Restarted again, and the driver information corresponded to the info for the latest driver, the one I had installed. And no blue screen! Huzzah! Resounding success!

...and now it's gone again. And now my computer freezes occasionally while streaming video. No blue screen, it just freezes and the sound buzzes until I force it off with the power button.

Now I suspect your MB, GPU and RAM. First try to take out the RAM sticks and clean it with a rubber/eraser(the gold connectors of RAM). Then reseat it properly.
If you have two sticks try one at a time. See what happens.

Another thing you can do a clean install of Windows. If your components
are good no harm trying this.

If the problem persists than I am afraid it's your GPU or MB. You can try another thing take out the GPU(if you can) and run the laptop on integrated graphics, see the result. If you see no changes than it's your MB. The best thing to do at this point send it for RMA or take it to a local store. Pro's can help you. Good Luck.

Ok, I appear to have solved the freezing problem. If RAM can be the cause of freezing, then it looks like that was it. I took out the RAM sticks and there was some crud on them, including something the size of a Grape Nut. Put them back in, started back up, I've had the Kitten Cam up for like an hour and no freeze. However, when I started up the Nvidia driver was there but said "device cannot start". Then after a few minutes it switched to the VGA adapter again. I guess reinstalling Windows is the only thing left to try. I need to find a way to do that.

EDIT: Scratch that, still freezing. I really don't want to try a clean install, but I guess that's the last thing to try before sending it in to professionals. I'm almost certain the GPU can't be removed.

I went through a very similar experience, It was surreal. Both my Geforce titans had disappeared from the device manager, and 2 of my three monitors were not working. The center monitor was working but the resolution was totally off. These are the moments when your spine chills, and panic sets in.
The computer technicians said it could be the ram or mother board or power supply, Or simply malaware. I was desperate. The PC seemed to be working ok but anything graphic related was out. I reinstalled Nvidia drivers to no avail.
The next day took my PC to the tech, who booted it up and the machine ran perfectly (Win7). Both my titan cards were back in the display manager. WOW. Although relieved, I felt i was in a bad dream, How is this possible?
I went back home, plugged in my PC to the APC back up UPS, powered up win 7, and the same exact thing..the titans has vanished!! My screen resolution looked horrible.
In an act of desperation, I look to the floor and see the UPC sitting there, an APC PRO 1000.
It seemed to be working correctly...surely it can't be the UPC?
It turned out it was the UPC. The UPC had gone bad, but with no warning messages whatsoever. In turn it was not powering up the power supply correctly which in turn had made my two Titans disappear and my resolution screw up.
As far fetched as this story is, I was very lucky it was only the UPC and not my two titans or motherboard.
