I got a new 860 evo and it worked for a day then I switched motherboards and it stopped working. It would show up in bios for the first couple boots but wouldn’t show up in windows but not it’s completely stopped showing up in bios. I have a ASUS z390e gaming motherboard with a m.2 ssd and hdd that are currently working but the new 3rd isn’t. I’ve updating bios to the newest and have enabled csm. Please help and thank you.

List your specs like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:

Then mention which slots and SATA ports you've populated on your board with your storage devices. Also, if you can get into BIOS without much trouble, check and see which BIOS version you're currently on.

I have slots 1 and 3 filled with the hard drive and the not working ssd and the secondary m.2 filled. I’m on version 1305 for the bios which I just updated to.

Read your motherboard manual.
Some M.2 slots on some boards share internal wiring or resource paths with some SATA ports. The end result being that if you have something plugged into one of the 'shared' SATA ports the M.2 slot gets deactivated.

The m.2 had windows installed on it from before I changed the mobo and I can boot into windows from the m.2 which is recognized along with the hdd.
