G73jh - BSOD under video card usage.

I have three dump files of a laptop I have been trying to fix. Here is what I have been able to determine what happens as a roadmap. Two are from running TERA, the most recent one is from running Furmark (050712-25537-01.dmp). This means the computer has crashed under both DirectX and OpenGL environments.

It's an ASUS g73jh. The specs are at this link:

Unfortunately this laptop doesn't have the original CDs. I still however can get copies of required software if it comes to that. This was an ebay sell.
This is making it very difficult to get drivers for other devices on the laptop.
This laptop is not being overclocked. It has been left overnight with me so I can try suggestions and I can extend this time frame as necessary.

Any time the video card comes under usage (League of Legends, TERA, Furmark) the laptop monitor will flicker for a fraction of a second (I assume this is TDR working) and eventually it will go to a black-white vertical pinstripe screen for a few seconds and then ultimately BSOD (I assume this is TDR finally failing). Drivers have been reinstalled and completely reinstalled at least twice.
The catalyst version is 12.4 mobile. I'd like to try a 12.1 mobile. 2-3 are off limits.

I'm open for suggestions and completely stumped. This laptop is apparently brand new and out-of-the box (it looks it and acts it for the most part, anyway).

Re your stop-0x116...
"It's not a true crash, in the sense that the bluescreen was initiated only because the combination of video driver and video hardware was being unresponsive, and not because of any synchronous processing exception".

Since Vista, the "Timeout Detection and Recovery" (TDR) components of the OS video subsystem have been capable of doing some truly impressive things to try to recover from issues which would have caused earlier OSs like XP to crash.

As a last resort, the TDR subsystem sends the video driver a "please restart yourself now!" command and waits a few seconds.

If there's no response, the OS concludes that the video driver/hardware combo has truly collapsed in a heap, and it fires off that stop 0x116 BSOD.

If playing with video driver versions hasn't helped, make sure the box is not overheating.

Try removing a side panel and aiming a big mains fan straight at the motherboard and GPU.

Run it like that for a few hours or days - long enough to ascertain whether cooler temperatures make a difference.

If so, it might be as simple as dust buildup and subsequently inadequate cooling.

I would download cpu-z and gpu-z (both free) and keep an eye on the video temps

There were issues with video card drivers in G73JH after people tried updating to any driver not provided by Asus. Easy fix.
First, get the disks provided by Asus to install your OS, etc, so you'll have it all factory fresh. Then flash the video card BIOS by following this link:

Once the video card BIOS is flashed, you can upgrade to ANY newer versions of Catalyst WITHOUT issue.
Congratulations on your purchase of a premier gaming machine--there is little it won't do. I got mine super-cheap also, because the original owner tried to upgrade using a standard video driver without flashing the BIOS, ended up with the crashes, and sold it before doing the research.
Now I have a beautiful machine, factory fresh, at half the price, and I LOVE it.
Also, ASUS support is very competent.
