You need to check laptop model, or just measure power port and check against https://www.cui.com/blog/selecting-appropriate-input-and-output-plugs-for-your-power-adapter

After checking some 4090 rendering posts it mentions that when rendering it uses about 300-320w for GPU. I would think if you would get boot error that would be pcie problem. Maybe it is some signal integrity problem, when rises goes too close to PSU or when they are near MB PCI-e slots and rises are really close to each other. Clarifying my previous post, main task now is to rule out PSU, by checking if PSU A can run two GPUs and motherboard, cpu. Quick search showed that a lot of posts with people hacing PCI-e problems with this motherboard, here's one. https://forum.level1techs.com/t/help-with-wrx80e-sage-se-render-server/190742

I would start with disconnection one GPU and test again. that would check if powersupplies are enough or pcie lanes are enough. EDIT: Did you remove GPU that is connected to PSU which also runs CPU and MB?

In my country 5995wx costs 7k eur, I would better get this combo https://www.ebay.com/itm/175786915446?itmmeta=01HX68FD2YFBQAV9AK7CFTG8P0&hash=item28edb77676:g:idMAAOSwmg5kluPf&itmprp=enc%3AAQAJAAAA4H6TInk5jVyeNvU85r%2B0f3U48zAtUl8Z61Ad3DBZ2%2BWWYwv6yXBOun0Cmq%2FatamAuUzptFZmfxeMadgQGe%2F14Nu8CdFfB9oaTKsrnBOrlcXP%2B%2FRNcsZ2QbHiEN2HRrJ8mucgljb6TF6279SMsTv%2Bbk61fztOZz6w4pS8PaiBIDq0Mo4Oj%2Fy7fvPJnuMViAyk6r7SiHrGy8NLlw0SWTz0Av7XcF53I2iy4%2BklbupJ3m6MnMwlMcBj8bmdLM2b0yOFNBAyYgqnVkCw6bEdDq6ylfZgWiqaVF1V8AkrV8C13Xwv|tkp%3ABk9SR8jRvcjpYw

Heres build with microcenter builder with 4070 super and ryzen 7700x for 1500$, if you select your local store you should check if 7800x3d bundle is in stock https://www.microcenter.com/site/content/custom-pc-builder-intel.aspx?load=2e1ed771-426f-4485-a6d8-b753a7ff3edb

Still would push for this one, 100 Eur more, but you get almost 2x fps in any game. Okey if you don't want to go with amd you still need to choose 4070 as the gpu, or buy used GPU. https://www.youtube.com/watch?v=Eyuukli2epw

I think this one with 14th gen fopr 100$ more is better deal. https://www.microcenter.com/product/671237/powerspec-g446-gaming-pc

whats current PC your father is using, new PC with 3060 sounds bad. Maybe Don't upgrade GPU and do when theres more money for that, maybe use old case.

Did you follow thisd guide? https://rocm.docs.amd.com/projects/radeon/en/latest/docs/install/install-pytorch.html Theres specific pytorch version for amd gpus.

Similiar thing happened to friend of kmine, his sssd was dying, reinstalled win then good for week or two and after that same, stuck at loading win or at boot logo and no boot option

There are some software privacy solution for specific dell and hp monitors, you can find what local you have. EDIT: seems like that only works for their laptops.

Thats great deal for 12c laptop withg 4070. Hope Asus TUF16 quality and good cooling

Maybe that's some bitcoin miner, what does windows defender say about it?
