Also is there a chance the CMOS battery failed while I was connecting it? I was considering getting a replacement just in case, even though it's a new motherboard. How did you connect the CMOS battery? You should have two pins labeled "CLEAR CMOS". Just unplug the PC and connect these two pins (I use a flat screwdriver). It’s a bit uncertain but worth a shot. Have you attempted to remove the GPU and disconnect the internal GPU? That might be helpful. If that doesn’t work, or if you can’t fix it by clearing CMOS, or by swapping RAM (have you tried a different stick?), or by removing the GPU entirely, then the next thing that comes to mind is the VRM on the motherboard.

How did you jump the cmos battery? You should have two pins called "CLEAR CMOS". You simply unplug the PC and jump these two pins (i use a flat blade screwdriver).
A bit of a long shot but worth a try - have you tried to remove the GPU and run off the internal GPU? Probably worth trying.
You mention that "it flashed the bios screen, the cpu temp read 91c, then crashed." I don't know the order of operations nor do I have a schematic but if this is a hardware issue, I wonder if you fried a cap in the VRM on the mobo. Don't replace the mobo on this guess, but if you can't rectify by clearing CMOS, or by moving RAM (did you try 1 stick?), or my removing the GPU, then the next thing that comes to my mind is the VRM on the mobo.
I tried all of your suggestions, and I jumped the two pins with a jumper cap. If the VRM is shot do I need a whole new motherboard? It's still within the return window for Amazon, I'm thinking about sending it off anyway just to avoid a lot of head scratching.

well, if you tried removing the GPU and still have the issue, then I cannot think of anything else. Maybe somebody else has something. Yes, if the VRM is fried you need a new mobo.
It's hard to troubleshoot via a forum thread, so don't do it based solely on my attempt to assist.
FYI - I have 30+ years of troubleshooting electronics, but even with all the tools and schematics available sometimes I don't identify the bad part correctly the first time...

I appreciate your help anyway. Amazon has replacement for non working components at no charge and two day shipping, so I'm going to take advantage of that. I'll post back here in two days if my new mobo still doesn't work.
Someone is asking if the CMOS battery might have failed while they were connecting it, and whether they considered replacing it even though it's a new motherboard. They also want to know how they connected the CMOS pins and what steps they took before the system crashed. Another person suggests checking if removing the GPU exposed internal components and recommends trying that approach. There is a mention of the BIOS flashing, high CPU temperature, and a crash, with speculation about possible VRM damage. The original poster tried all suggestions and used a jumper cap to clear CMOS, but if the VRM is damaged they think a new motherboard might be needed. The advice given emphasizes trying different fixes before jumping to conclusions.
I also have a quick question—what if the VRM fails (I have a month to return the motherboard so I’ll get it checked)? Does that mean I received a defective board where the chipset simply can’t handle overclocking? It was an Asus Prime Z270-A, which got good reviews on PC Parts Picker. I’m not sure if I’d still be able to overclock it.
I have another brief inquiry.
If the VRM turns out to be damaged (and I have a month to return the motherboard, so I’ll get it checked), does that imply I received a defective board whose chipset can’t handle overclocking? It was an Asus Prime Z270-A, which was well-reviewed on PC Parts Picker. I’m not sure if I should have overclocked it or not. I just want to know if there’s still an option for that.
That motherboard should be fine for overclocking. I don’t understand the method you used in BIOS—whether it was a bad board or something you shouldn’t have changed. Most BIOS systems have safety limits, but I’m not sure what settings were adjusted.
The motherboard includes a feature in the BIOS named EZ TUNE. One of its options is EZ overclock. It prompts about the CPU cooler you have and then selects a suitable overclock setting for it. I was reviewing the BIOS settings and had turned it on before completing the setup or updating.

hmm, that's curious. It doesn't seem likely the problem came from the motherboard unless there was an issue with the board itself.

hmm, interesting. that doesn't seem likely to be the cause unless the mobo had a problem.
update: received the new mobo, installed it, still has that little red light. no boot or post. i think i'll try replacing the cpu next, unless it could be the pcu. i'm not sure if i damaged my i7.
