Hello, I recently downloaded an audio driver (Realtek Audio Driver V6.0.1.7304) for my g750jz but when the computer restarted after installation, screen was divided into 6 little screens, I dont know what happened.

41613

41614

41615

even the boot setup is divided:

41616

If I start Ubuntu, screen works good there:

41617

but when I restart the computer is divided again.

Can anyone help me?:(

Greetings.

Without a doubt, you're going to need a repair. Seeing that kind of problem before the system has even loaded an OS points to a hardware problem, because at that point the drivers haven't even been loaded. Since I believe the entire G750 series has two GPUs (the one built into the processor, and the Nvidia GPU) the problem can be masked when an OS is running on the GPU that doesn't have the issue - Ubuntu is probably using strictly the Nvidia GPU, while Windows and the BIOS/UEFI use the integrated GPU (which appears to be toast). I might have that backward, but overall the case still stands.

One way or the other, you're almost definitely going to need to get that repaired.

Wow.. what the hell.

This is like the ultimate april fools thing right here.. sadly, it isn't april fools.

When did this start to happen? Right after installing the audio driver?

If I was you, I'd do a backup of everything on the hard drive, use the BackTrack program and yank it off the hidden partition. Make sure you have nothing else running as you do it and revert your system back to factory. Hopefully it'll fix it.

I can only assume that Optimus got damaged somehow and now is trying to use the Intel GPU and the NVidia in some retarded SLI ':f

Doubt it's a hardware issue. Possibly just the BIOS doesn't know what GPU to use. Could do a reflash? ;x
