New Build Wont Start - MBO posted, Cpu Fan wont spin - PLZ HELP!

[fallenhero]

Going crazy...please help.
I built my new computer last night, however it won't start. There is power to the motherboard, because I can hear and see the fans when I turn it on, it also beeps when I pull the graphics card so I think the board posted OK, however the Heatsink fan doesn't move. It initially spins a rotation or two and that is it. It does the same thing when I power it off, just a initial spin or two and then it stops. Any ideas...I would be so grateful.

Here are my system specs:
Intel Core 2 Duo E6750 Conroe 2.66GHz LGA 775 65W Dual-Core Processor
GIGABYTE GA-P35-DS3L LGA 775 Intel P35 ATX Intel Motherboard
Rosewill RP550-2 ATX12V v2.01 550W Power Supply
4stick of - G.SKILL 1GB 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400)
APEVIA X-JUPITER-JR G-Type X-JPJGT-BK Black SECC Steel ATX Mid Tower Computer Case

Thanks so much for your help!!! It's been a while since I've built a system..so frustrated!

Welcome to PCM.

Do you have both the 24pin and 4pin power connections in place? If not, plug em both in.

If so, try this out of the case troubleshooter: http://forum.pcmech.com/showthread.php?t=132409 and let us know the results.

Also is the CPU fan plugged into the CPU fan port on the motherboard?

I'd try a different power supply. Rosewill doesn't manufacture their own power supplies (or anything else) and buy from other companies so you really don't know how good it really is. It could be a rebadged L&C or DEER power supply for all you know.

Rosewill has two ODM's. One is Youngyear, and ATNG.

Youngyear makes Apevia, Logisys, MGE, Ultra X-Connect, and Rosewill psu's

ATNG makes Coolink, CoolMax, Rosewill

At least, I think so...
