Just built System. Fan turns on but nothing happens

Hello,

I just built a system.

AMD 64 4000+
Zalman 90mm heatsink/fan
foxconn mobo
1GB ram
380W power supply

When I turn it on the system fan and cpu fan power up. Cpu fan is connected to the motherboard. System fan is connected to the psu.

no display.
UPDATE:
I unplugged the cable connecting the hard drive to the motherboard and now I can hear the hard drive spin.

But NO Display? I should at least get and "invalid system disk"
What could be wrong? Is the 380W to small for my system.
 
take it out of the case and lay the mobo on a non-conductive surface with just cpu, mem, and vid installed and try it.
 
no one has anything compatable.

it's ether the cpu or motherboard? the cpu fan comes on and that is connected to the motherboard. what do you think?
 
no beeps. so i guess it is the motherboard.

this is the thing, i guess i might as well send back the cpu too (to be safe) because i only have a 15 day return policy from newegg.

will newegg pay for shipping etc... (will this cost me anything)
 
Reset the CMOS. I can't say that this will work for your mobo but its worth a shot. For my finicky DFI Lanparty NF4-SLI, I sometimes need to reset the cmos after a minimal system change.
To do this
1) Turn off system power (flip switch on psu)
2) Take out mobo battery
3) move CMOS Jumper to reset position
4) Wait (I usually wait overnight but I bet that is overkill)
5) Move Cmos Jumper back to normal position and put battery back in
6) Let us know how it worked

One more thing, does your mobo have a boot up diagnostic (usually a series of lights on the mobo indicating what is working in progressive order aka start up, cpu, ram, video, bootup

Have you tried this?

And also remove and reseat the HSF

 
First try with the bare minimums, CPU/heatsink, a single stick of ram, video card(you didn't list one, onboard video?)

Do you have the 4 pin ATX connector plugged in to the motherboard(square, with 4 pins, 2 yellow wires, 2 black wires)

If you still get nothing, do what some one else already suggested, use the bare minimums outside of the case.

EDIT: p.s. if you still get nothing with the bare minimum outside of the case, try with no ram at all, and see if you get any beeps(will have to have the speaker hooked up to the motherboard of course).
 
"What could be wrong? Is the 380W to small for my system."

Was once in a similar situation. I had a 350W PSU (18A on +12 rail). Newly built system would power on for about 2 seconds and then go dead. It was suggested I try a more powerful PSU. I tried a 450W PSU (with over 25A on +12 rail) and the computer started right up and ran with no problems.

It is certainly worth a try.
