    Hi all. :)

    Are two problems.
    1. My Dreamcast always loses the date/time when I turn it off.
    2. My Dreamcast resets when there are variations of simple energy. (The simple act of shutting the door of the microwave oven resets the Dreamcast)

    The PSU, the control board (where has the battery), and GD drive were tested in another mainboard, and everything works normally without the problems cited.

    The mainboard with this problems has the following mods:
    1. SD card mod
    2. VGA mod
    3. Reset mod
    4. Battery mod
    Note: The VGA mod stopped working, but the problems mentioned here already existed before this.

    Seems to be something on the mainboard. Maybe some component or some kind of bad contact, I don't know.
    Thanks to anyone who can help. :)

    Try sticking probes into the voltage outputs of the power supply and record it as you do something that will reset it. If the voltage dips, you can be sure that the PSU has died, easiest thing to do would enjoy to replace it with a PicoPSU. If not, the main board or something past the PSU is at fault.

    Not sure what this "reset mod" is, but I would recommend replacing the PSU with a PicoPSU
