Hiyya and welcome viddog mate just go into your BIOS and if you know which of the drives you installed on just set it to boot from it.
You may have been better setting a SSD for boot purposes and the others for data but there again that would depend on the budget.
If it were me I would disconnect the other drives - see what happens then add the others one by one. If the problem starts up then one of the drives must be interfering with the boot process.
By the by did you prepare the drives before installing? Now some of the others who know better than me might say not necessary but I always do this before I use the drives. SSD Alignment
I know this is for SSD's but the fist page stuff
I use for all drives as I said.
If you want to make sure the drives are absolutely clean use the Partition Wizard to wipe them - takes a while and then follow the above process but you need a running machine to do that.
