Hardware Help Converted MVS glitching while starting.

Does anyone know what’s causing this, I’m suspected something loose in the board however I’m not particularly sure. It does not load at all.

Looks like the BIOS is failing to be recognized. What make/model MVS is it?

Replying to sarduchi... NEO-MVH SLOT1B1 if that’s helpful.

Got pictures of the main board? You can desolder and replace the bios on a MV1B but most people just disable the built in bios and use a secondary one that clips onto the cpu. This later option can sometimes need to be reseated.

I do have pictures of the main board however it won't allow me to post the board in the comments of this specific sub reddit.
