    Changing a power supply should not result in that BIOS message. Did you reconnect every power cable - to the motherboard jackS, to the hard drive, to the SSD, to the GPU?

    What did the BIOS message tell you to do?

    Did you ever successfully get Windows to start up?

    Possibly the cmos battery was dead; removing the pw supply cleared bios settings. Check bios mode matches how windows was installed ie legacy or uefi.
