None of which is caused by Windows OS itself. But if you can remote access into your desktop if needed, there's nothing wrong with going for a Mac.

I mean your keyboard seems to have every button you need already. I don't like the only Fn key on the right because my right hand is controlling my mouse, suppose it's a keyboard for lefties? But if you're fine with it, it's not a problem. QMK/VIA is just key mapping to the max, it's not necessary for programming.

Think of water pipes with information as water and PCIe lanes as the pipe. A 16 inch pipe is going to allow more water flow than an 8 inch pipe right? and obviously the 16 inch will be physically bigger. However some times they will have x2 connections on x16 slots or cut one end open for cards with x16 slots to fit in, but their max connection speed is limited by the connection. For B550, think of having only a single 16 inch pipe for inlet but many 4/8/16 inch pipes as outlets with control valves, it allows each outlet to get the most water output they are rated for but wouldn't if they are asking for more combined than the inlet could provide.

Maybe it's overheating? Monitor its temperatures. You have an iGPU in there don't you? Try take the card out and play Elden Ring on the iGPU and see if it shuts down

It's not just phones and tablets, PCs don't have hardware AV1 decoding before Nvidia 30 series, AMD Navi 2X (RX 6000 series) and Intel 11th gen. Desktops wouldn't be bothered much but laptops will face the same problem.

7th gen and 11th gen. Honestly I dont think 14th gen is that disappointing compared to those two

Get tier D or better

If restart doesnt work, you'll have to RMA it. It's a laptop with everything integrated, not much you can do.

Lifting from one side as in picking it up with one hand? Didnt notice any noise other than plastic squeezing against each other. Did not try press down on the speakers.

I think it's pretty quiet. Typical low profile membrane quiet.

You might have to choose the boot drive in the BIOS again but that's it.

Sounds like you turned sticky keys on. It's a feature in the operating system.

what benchmark is that? They blacklist some like Furmark because it pushes cards too hard and breaks them despite staying within power limits, and blacklists can be expanded. Try an actual game instead It could also be an out-of-date Afterburner problem, OC software like this has to communicate with the driver so a driver update could break OC software too

But default power limit of a 12400F should be 65W, not 75 or 60? Either way, they are adjustable in the BIOS. Exact wording differ between companies but it should have "power limit" or "PL" in the name, say turbo power limit or PL1, with a number input. You could set it to whatever you want, I think the maximum allowed for a 12400F is 117W but Intel's not enforcing board makers to follow power limits because higher power makes them look better in benchmarks.

Did you follow instructions of the PDF file that comes with the BIOS download?
