Question Dead Intel 0KV3RP motherboard ?

[Nyphrodel]

I got my daughter a DELL XPS 8940 Desktop PC in 2021. It's an i7-10700 CPU and the other day, it just went dark. This, of course, would have to happen just before Christmas. She's driving me crazy because she feels totally unconnected to the world without it. After looking it over, I'm about 99% sure the system board is dead.
I just purchased a new PSU because she wasn't get enough juice. So, I went a little over what she needed and purchased a Corsair 850w because we were thinking of future upgrades. I haven't installed it because it won't fit in the case because DELL uses as much proprietary equipment as possible.

Our original plan was to get rid of that proprietary PSU (it looks like a shoebox, for God's sake!), get a new case, upgrade the system board, and the CPU. She loves her Nvidia 2070 Super, so I don't need a new gpu.
I refuse to buy a prebuilt system again unless I can find a spankin good deal for Cyber Monday and just swap out some of the parts.

That aside, does anyone have any suggestions of where I should start? I'm loathe to spend the money that I've been saving for Christmas, so I want to go cheap, if possible. Maybe just replace the motherboard, for now...? I'd love some input because I'm super busy right now, and I can't think straight because she's driving me crazy! This is important! She just went to her room and slammed the door...AGAIN!

She uses her system for watching streamers, playing video games, and she plans on being a streamer herself in the near future.

Best advice, please?

if you do plan to upgrade the system innards for something concurrent and power hungry that Corsair unit should suffice. Sadly as you've found out the hard way, the parts inside the Dell prebuilt is proprietary, namely the PSU, case and motherboard.

The simplest solution IMHO is that you drop the processor, ram, storage and GPU onto a known working B460 chipset motherboard(sourced from a friend or neighbor) in order to verify that it is indeed your motherboard that's conked out, then into a small form factor chassis to round off the build.

If you're located in the USA, you might be able to round off the latter two purchases within $100. I'm assuming that the rest of the parts, namely the CPU, ram, storage drive(s) and GPU aren't compromised while either the motherboard or the PSU are to blame for your prebuilt's demise.

which does cost more than a case and motherboard, just off the top of my head.

There might be more worthwhile suggestions from the community though, so please hold out for more to show up.
