building my pc...help me out

Hi guys,

I have bought all these components

Phenom II X3 720BE
Biostar TA790GX A2+
Palit GTS 250 512mb
Kingston 4gb ddr2 800mhz
WD 640gb hdd
Crossair VX450
Zebronics bijli cabinet


I have got a few questions regarding the installation of these components.

1) Do i have to change some jumper setting on the mobo.

2) Should i clear the cmos before booting it for the first time.

3) Is there an critical thing that i have to configure in bios. (i know i have to choose the primary and secondary hdd, but anything apart from that, something related to voltage etc..)

4)My cabinet came with a small wire with a black round speaker. The end of the wire has speaker written on it. Do i have to use it. I think the mobo already has that black round speaker.


Sorry for being such a noob
I am doing this for the first time. I just dont want to screw up anything.
Also let me know if there is anything important that i might need to know

1st ques: No don't change any jumper settings on the mobo

2nd ques: No need to clear CMOS

3rd ques: No need to change anything from BIOS. Just disable 3rd boot device if any. Set first boot device as CD-ROM as u'll need to install XP/Vista on it. And second as Hard disk

4th ques: If u think that speaker is on that board then its ok. Speaker is not important.

Important: Don't forget to apply thermal paste on ur processor and then insert it on ur motherboard. That's it.
