hi there im new here and need help

, i just bought a new motherboard ( Gigabyte nForce 430 S939 PCIE MATX DUAL CH DDR400X4 TV OUT ) and CPU ( AMD 64 3700+ ) and everything looks to be connected correctly but when i switch it on nothing seems to happen, im just wondering if my PSU isnt powerfull enough as its 300W only, could this be the case or is it something else u think ? i mean the PSU says it supperts AMD but mind u my last CPU was only 32bit and the motherboard was really old so hmm ? im just hoping its not the parts that i orderd thats the problem...

any advice would be great thanks

Welcome to PC Help Forum.

Let's investige your theory on the PSU. What else do you have in your PC?

hi thanks for the welcome ..

i have 2 hdd 1 thats 80 gig and another at 160gig
2 ram cards are installed at the moment a 512 and a 256
theres a dual layer dvd writer and a standard cd player
and a 3 1/2" floppy drive

also something i noticed was that the psu socket on the MB was 24 pin but my psu was only 20 , not sure if that would be the problem ? i mean nothing happens atol when i try switch it on the fans dont start or anything , the only thing i hear is the PSU power down when i switch it off, its like a little sqeual sound for a second

What about the graphics card?

Also, yes that pin issue could be a problem - you may need to purchase one of THESE

theres actualy a gfx card built in to the MB untill i buy a new one
