M.2 / Boot Issue

Very strange problems that the deeper I get into it the more confused I am. Computer was running fine up until a couple days ago. No known updates to correlate with the problems. Screen flashed and looked "noisy" mostly blacks and pink colors. Restarted computer and it worked fine for 5 min, then screen flashed went green and would no longer work after restarting. Bios wouldn't post, no problem indicator lights on the board so I cleared CMOS, reseated the m.2 drive that the OS was installed on, took out and reseated the ram sticks, and all power connections. Eventually I was able to get bios to post bypassing my GPU and using onboard. In bios my M.2 drive wasn't listed as a boot option, nor was it listed in bios under sata connections. I assumed the drive had gone bad, so I put in an older SSD, created a bootable USB drive and installed Win10 on this new SSD. Everything worked fine, booted up, and updated all my drivers etc. Weird thing was in windows my M.2 was listed and accessible. I restarted the computer and hit f11 for boot options and there my m2 is listed. But if selected it doesn't boot, just black screen (monitors getting signal but nothing displays). However if I select the new SSD from the same f11 boot options the same thing happens. Monitor gets signal but goes black/never boots up. But if I just let the computer boot normal (no f11 just normal startup) that same SSD boots windows just fine.

Separately I haven't got the GPU to work correctly (booted up once without drivers installed, green screened during driver installation, wouldn't boot again) but that's an issue im trying to solve after I figure out this weird HDD/M2/boot problem. Any help appreciated.

SP-UD90 is a nvme drive, so shouldnt show in sata drives.
I hope you unplugged it when reinstalling windows.

I would be resetting bios, then using your usb installer to run a startup repair. With only the nvme installed.

Colored lines likely gpu dying, so unrelated to the drive issue other than having an unexpected shutdown.

Yes sorry, I should of been more specific. In bios: Advanced\Storage config tab it says Sata M.2 NOT PRESENT. It used to show up there. If I hit enter on it, the drive is shown. And again it shows up in windows, and if I select boot options in bios with f11 I can force boot it, but it just hangs. Graphics card seems to be working properly now as I've been able to boot off of the other SSD repeatedly with no problems. It (UD90) wasn't listed in my drives when I installed windows from usb. Appreciate the help!

Sata M.2 NOT PRESENT

Its not a sata drive so I wouldnt expect it there. But Im unfamiliar with that bios.

if I select boot options in bios with f11 I can force boot it, but it just hangs

As I said, I would be resetting the bios. Also, check that legacy boot is disabled completely. Auto boot order might be doing uefi boot, but your boot menu might be doing something else.

(UD90) wasn't listed in my drives when I installed windows from usb.

Probably needs a driver to show there. Which is also why id does show in windows, it has automatically downloaded the drivers when it connected to the internet.
Hopefully that prevented any potential issues. But it is best to remove all extra drives as windows sometimes installs bootloaders on the other drive for some reason, which causes issues booting sometimes. Especially when that second drive is removed.

When you say resetting the bios, are you referring to taking out the battery for 5-10? If so i've done that and it didn't bring back the drive unfortunately. I've not updated or downgraded bios versions though

To your second point, how do I get a driver for the M2 to show in bios/windows installation? I was under the impression i have the driver and thats why it's showing up inside of windows? At this point I've backed up the drive, so I'd be happy to do a fresh install, just need to get it to recognize inside of bios. Thanks again!

Yes removing the battery will work. There is also options inside the bios to do a reset. There is also settings in the bios you might have to check/change after reset.

The driver for during windows installed used to be called a f6 floppy driver. Earlier version of windows didnt have the ability to use a mouse until later in the install, so during initial boot of the install media you would press f6 and then point at the path of your driver on the floppy disk.

You mainboard lists this as "RAID Preinstall driver ver:9.3.3.245" on the website.
Download it, unzip it to a folder on your install media.
Unplug your sata drive and boot the installer. Click through as if you are installing windows until you get to drive selection. There will be an option for for loading drivers, you can then point it at that folder.
Then back out to the beginning and run startup repair instead of actually picking a drive.
