Predator Helios 300 G3-571 - Unusable GPU

Moderig

Greetings,

I received a Helios 300 laptop a few months ago to fix; I presumed its only problem was a broken screen. However, as soon as I factory reset the device and attempted to install the GTX 1060 drivers, I received a blue screen of death:

PAGE_FAULT_IN_NONPAGED_AREA from nvlddmkm.sys

I learned that nvlddmkm.sys has to do with the graphics drivers, which proved my suspicions that something was wrong with the GPU. I did everything in my power to fix the solution, some examples being:

• Factory resetting
• Downgrading/upgrading windows
• Installing old drivers
• Using the eGPU Code 43 script

After my first factory reset, GeForce Experience finally installed a set of drivers. However, the NVIDIA Control Panel was not accessible at all, even if I attempted to open it. No matter what, I received a Code 43 for my GPU in the device manager, which always disappeared after installing said drivers, but then reappeared after a restart. Every game I tried running at any point always used the integrated graphics.

I've heard that this issue likely spans from hardware problems. I've disassembled this device a few times to replace screens and disk drives, but I have no idea where the GPU is. I know it is soldered to the motherboard somewhere, but what exactly does it look like? I have watched several disassembly videos only to find no mention of the GPU anywhere. My hope is that whatever is physically wrong with the GPU, I can fix, like a loose cable.

Do you guys have any other suggestions? I've pretty much exercised all of my options in terms of software.

@Moderig the GPU is a chip and has to be unsoldered in order to take the chip out. It is underneath the heatsink. Solving problem with these chips is usually difficult.

I see, thanks. How much would a replacement GPU chip cost in this, or is it even worth it? Do you think there are any other solutions I can use to possibly fix the current GPU?
