Are you using an ATA-100 rated cable with that brand spankin new drive? 
  Put the HDD at the end of the cable with the jumper set to master.  On 
first boot up go into the BIOS to let it auto recognize the drive.  Try 
just the HDD drive by itself just to see that it works.  I would put the 
  CDRW on the second IDE channel as Master.  My Samsung works great that 
way.  Some CDRWs will only work in this config.  There are reasons you 
would want this to be on its own channel that I won't go into right now.

To see if it is a power problem, plug in one device at a time per boot 
up.    You never did say what wattage your pwr supply is.  Is it rated 
to handle a P4$$?  A 300 Watt should do.  Some lower watt ones will work 
in OEM systems, but they have been through a lot of testing and if you 
blow one they will replace it, if they trust it, I trust it till I 
replace it.
