HLEP! Need new computer components.

I need a new motherboard and Power supply.

I have an intel core 2 duo CPU with the heatsink that was supplied.
WinFast TV DTV1000 S that I have never managed to get working... but meh might try when im bored.
gf9400gt Nvidia gfx card.
Netgear wg311v3 wireless pci adapter
and a 2g ddr2 chip with a few ddr1 chips but they are insignificant.

my limit is 200 delivered. Thanks for your time. I dont know why i cant figure it out. Everytime I get into it my mind blanks xD

You're going to need more info about the CPU - its codename, clockrate or date of release - otherwise it's impossible to know which socket you'd need.

Depending on where you live, it might be easier to pick up parts. I'm using Umart Online (order online, pick up from warehouse), but you need to find which parts you need.

You need a motherboard with:
x socket (pending CPU info)
DDR2 RAM slots
PCI slot for DTV
PCI slot for wireless
PCI-E slot for the graphics (just confirm that, it's unclear).

Do you have a Case, HDD or DVD burner?

Also, I recommend whirlpool forums for computer questions, that's where I went when I wanted to put together my new build. They actually know what they're talking about, I just know how to google stuff.

775 CPU haha (DELETED)-who knows what I was trying to say.... anyway this MB I think has everything I need http://cgi.ebay.com.au/Gigabyte-GA-8I945GMF-RH-Pentium-4-LGA-775-Motherboard-/130484955746?pt=AU_Components&hash=item1e61826a62#ht_3327wt_908

have 2 dvd burners (who knows why^^) Sata HDD idk what to say about my case.

Well, luckily most cases fit most motherboards. Just make sure it's not a slimline case or motherboard (ATX or something, I didn't do research).

As for PSU, just get one that fits the case, and make sure it supplies enough power for your parts.

Good luck.
