Problems with new build

Hi, I recently completed my i7 build and all worked first time;

i7 920
P6T Deluxe
6GB G-Skill ram
GTX 295
WD 500 AAKS
Seagate 250GB
LD 22x Dvd burner sata.

then yesterday morning i bought a new

TP-WN951n Wireless card
22x LG DvD Burner IDE
500gb HDD Seagate.

i installed the new components, the HDD worked.

i went to use the DVD drive and it will open and close but wont register in the bios or in my comp or under Device manager.
I am using the IDE cable that came with the mobo, it is labbled with HDD could this be the problem (I need a new cable)
i ve tried using the different colour connectors on the cable (Slave, Master)

Secondly my wirless card. i installed correctly and device manger registered it, then i installed the drivers and porgram off the disc provided.

the card was then registed as TP-Link Wirless adapter in device manager.
the program however which you need to get a connection (I Think) wont work it says that the card doesnt exist.
so i unistalled the program and then installed the Atheros chipset drivers from their site but still i cant seen to get it to work.

Please Help.
