PC software expert, familiar with hardware

OK, I'm fairly good with computers, but will need some support with a laptop past warranty and a desktop PC with 1.5 years warranty.

For the laptop it is regarding the GPU, it has 2, only one is being detected (the unwanted one) and the regular steps (Nvidia control panel, enabling/disabling etc) is not working.

For the desktop I believe itís the GPU as well, screen will go black then reappear after 5-10s, the PC is still running and the monitor works. I switched monitors, still does it. Going to try a VGA cable tonight in case itís the HDMI connection. Most of the time during these blackouts thereís no error, however when running BF1, it sometimes blacks out and maybe every 3 days it blacks out then crashed with an error stating it cannot find the graphic card.

All drivers have been updated correctly.

The graphic card is more than strong enough to handle BF1, itís the AMD RX470 8Gb version. Also, this blackout happens sometimes while on youtube.
So, some might tell me to return it, well Mediamarkt will accept it, then replace the whole desktop. This does not have to be done, with the amount I have installed on that desktop and the configurations, I will have lost weeks of time. If itís the GPU, itís a fairly simple fix. Iíd like a second set of eyes to confirm this but I also need to confirm that if I make the change myself, then I will not void the warranty. I talked with their customer service they claim if I come in, they could print something up, we will see this weekend. I donít trust them to do it themselves as I once did that, and then when they turned on the computer, it made a terrible whirring noise, then froze. They promptly exchanged it but refused to let me take out the hard-drive to recover files.
Before anyone criticizes my choice for mediamarkt, as many do, one has to remember that the products sold there do not reflect the store, an ACER PC is the same one sold at Digitech or melectronics as a blu ray copy of the hobbit is also the same at all 3 stores.

Anyway, willing to hire someone who has deep knowledge to give things a second look before I start taking things apart.

Re: PC software expert, familiar with hardware

For laptop: try to find gpu enable/disable option in your bios, maybe to update your bios to the newest one. At least that was the case with mine

For desktop: if you have more than one PciE slot, try to change it, it might work.

Re: PC software expert, familiar with hardware

As stated, everything has been updated and I've also tried dis/enabling

For the desktop, I will try it, if it does not void the warranty.

Re: PC software expert, familiar with hardware

I've never heard about laptops with 2 GPUs, what model is it, if I may ask?
Regarding diagnostics, sometimes it's worth booting from some live Linux USB stick, like Ubuntu live. Latest distros usually have latest Nvidia drivers, and AMD drivers can be installed on the fly (well, you can't reboot though, but you can modload them and restart the graphics).

Whatever tests you do, make sure you have a good backup of your OS and data.
Ideally, make a hardware-level copy of your disk(s) and experiment with a freshly installed OS on a new disk. It may be few hours of work to prepare the test environment, but you may loose days and months worth of work if you don't do so.

Gaming laptops often have 2 GPUs. My Acer does.

There is the discrete nVidia one and the Intel one bundled with the CPU.
I even have a little widget telling me which one is being used.

The system that manages is is nVidia Optimus

As stated, most gaming laptops have them. Actually pretty much any laptop with Radeon or Nividia graphic Cards have 2 as the HD graphics are built in and standard on almost all motherboards now. Might seem useless, but it's cheaper to make all the motherboards the same instead of making 2 seperate ones.

Laptop has already been cleared, all files on EXHD and as for OS, anyone with the free or registered copy of Windows 10 doesn't need to worry about that anymore, when the computer/laptop boots up after a factory reset, all you need to do is sign into microsoft and it automatically installs your OS.

Been testing the desktop, found that it only does the error now when in multi play and not while playing offline, sometimes still with YouTube. Never heard of being online (especially since I'm still connected while on single player mode) being the cause of an issue with the GPU...

If you mean Intel or AMD graphics built in CPU, I've never considered it as a "second graphics card", hence the confusion.
Anyway, best way to tell software from hardware problems, is to try another OS,
like Ubuntu Live USB from https://cdimage.ubuntu.com
