<<Now I am not a genius but generally when I have built computers in the past the hard drive is set as the master and cd rom as slave?>>
It all depends on how many cables we are talking about...and the type of cables.
Yes, you are correct in assuming that the boot drive (or only hard drive) should be configured as the master when looking at BIOS and such...but the optical drive should also be configured as master, on a different cable. That's for the old PATA/IDE setups common to all motherboards.
But...it's no longer that simple
Newer motherboards which have only 1 IDE connection ...provide the opportunity for users to only connect 2 IDE devices (hard drives and optical drives), whereas older motherboards historically have provided at least 2 connections affording the opportunity to connect a total of 4 devices (2 on each cable, 1 as master with the other as slave). The newest motherboards may not even have any PATA connectors, providing nothing but SATA connectors.So the old proverbial wisdom about not connecting the hard drive and the optical drive on the same cable...applies only to some motherboards, motherboards which have nothing but PATA connectors
To add more confusion...SATA connectors have their own pattern in the BIOS. Since each connector can only support 1 device, users don't have to worry about master/slave jumper settings...but they still need to look in the BIOS and see which connector/connection is depicted as master. The boot SATA drive should be connected to the connector reflected in the BIOS as master, IMO...although I'm not sure if this is the only connection pattern that will work.
We need to know what type of connectors each drive has. It's possible for you to have 2 or more PATA...1 PATA and 2 or more SATA...or all SATA.
If you tell us the manufacturer and model of the system you bought...or the motherboard manufacturer and model if you had it custom built, someone can tell you how your connections should go.
Is that a SATA optical drive or the traditional PATA optical drive? Same question for the hard drive.
Wiki has a decent article which gives a view of the SATA motherboard connectors (1st pic) and the SATA cables (2d pic). Some SATA cables have the right angle connector pictured, some are straight...but the end on the two looks as pictured.
FWIW: BSODs can be caused by many things, let's wait for info for you and then we'll try to get the connections to what should work smoothly...and go from there.
