Bad Drives?

I have 2 120gb Extreme SSD’s.  One was just recieved from an RMA.  I had to recently (today) replace the motherboard in my system due to a failure on it.  Now BIOS will not read either of the drives, but it does read my 1tb standard drive.  What in the hell is going on?  I’ve seem to have run into a rut of badluck recently but this is honestly too much.  Do I have some bad drives? Or what is going on?

do you have and external enclosure to test the SSD in?

The motherboard might not be compatible with the SSD. What’s the model number on this if I may ask?
