I just realized the PC speaker is not connected. I am currently trying to figure out how to connect it (any advice?), and hopefully I'll get some sort of beeping that will indicate what is wrong.

If I were to get an identical motherboard and just plug everything in like it is now, would it work? Specifically, would the RAID 0 work without any data loss?

Thank you for your advice on this headache of a situation,
