My 3TB D drive crashed my PC. Rebooted and it took a long time to start but it was fine, outside of my desktop being on the D. Turned it off to remove and recover the D and MB wouldn't post. Just nothing, so my Sys eng. husband troubleshot it and nothing seemed to reliably help. He ended up getting it to start by removing one of the sticks of RAM, and redirecting my desktop. It ran for a bit then froze and now it will not post yet again. We are completely stumped, it turns on, but no MB logo just nothing. We have tried many monitors, changing graphic cards, unplugging the c drive, nothing. Any help would be super appreciated. It is running windows 10, MSI B450 MB, The GPU just says Gigabyte on the part I can see and I can't remember what it is.
