New PC won't boot up

[EndOfHeart]

All the fans work even the video card fan and the lights turn on but nothing shows up on the monitor. Don't even hear a beep.

Athlon 64 3000+ 90nm
Chaintech vnf4 nforce4 zenith value edition for socket 939
Chaintech 6600gt pci-express
Seagate 80gb sata
rosewill cd-rw/dvd combo
samsung floppy 1.44mb
cosair value select ram 184 pin 512mb ddr pc-3200
Kingwin Mutant X with 420 power supply

I think it maybe the power supply but i'm going to keep trying out things. Also the power connector doesn't cover all the pins on the motherboard so it may get insufficent power?

Edit: the motherboard has 24 pins but the power supply only has a 20 pin connector so is that the problem?

Intel based boards are compatible with 20-pin but I've never read anything about AMD boards being that way, what does it say in the manual?

The ATX12V connector (that square one by the RAM slots) it's plugged in too right?

 

[EndOfHeart]

Yea its plugged in right. I had to email them for the manual (didn't come in the box) but they haven't responded maybe cause of new years dunno. I followed their online manual but even in that it say to refer to the book manual

Try removing the video card and RAM and reseating it

AMD boards should be, for the most part, 20 pin... the 24 pin setup is a S775 thing as far as i know.

What exactly are you looking for?

the 24 pin setup is a S775 thing as far as i know.

that board has a 24pin as well as the additional ATX12V

All A64s have the ATX12V ... the 24pin ATX might be a NF4/PCIe thing or it might be a Chaintech thing, dunno.
