Hey guys, this is my first thread and i was hoping to get some help.

I'm currently building a new box and ive run into some trouble.
I thought the build was clean but when i turned the box on i got nothing on the monitor.
The CPU fan didn't start up either, i checked it was connected and it looks fine.
Also there are 6 lights on the mobo that come on...but no beep?

Just incase you need the specs, here they are:
mobo - Gigabyte GA-EP45-UD3
cpu - E7400
ram - Kingston hyperX 1066mhz 2x2gb
gpu - Gigabyte 4670 512mb
psu - Thermaltake 430 watt
plus a hdd and a dvd drive

Any ideas on what the problem could be?
All help would be greatly appreciated!
Thanks

Did any of the fans start up? Or you press the button and nothing at all?

Yeah the psu and case fans started...just not the cpu fan :S

try one stick of ram

also make sure the power supple is plugged in all the way on the motherboard.

Well the power supply is plugged in all the way.
As for the ram, i don't really wanna turn it on again until i think i might have got the cpu fan working

Also just incase anybody was wondering, i checked both the ram and the video card in my current system and both work.

It can run a bit without the fan running. It takes a bit before the heatsink heats up to the frying point.

Try plugging the CPU fan into the other fan plug if you can. Don't worry if your missing a pin

Now make sure that the cmos is on and not reset.

I'm thinking the CPU or the motherboard most likely is DOA.
