so it turns on, no beep from the motherboard speaker (assuming you got one installed) and turns off right away or does it beep once (POST beep) then turns off..

try turning the system on w/o ram, if the mobo speaker (install one if you haven't) doesn't beep and it just turns off then it may be the PSU or mobo. if it beeps then it may be teh CPU itself.

When you put it together, did you make sure you installed the motherboard standoffs (if not already installed), and triple-checked to make sure they were in the right location? If they're in the wrong spot, or are missing entirely, you may short out something on the board. After the 4-pin/8-pin CPU power connector, that's the next thing I'd check.

Standoffs look something like this:

Yes all those are in there. I was able to get it to turn on and now my screen wont work. It has a no signal on it. i tried hooking it up in both mob and video card and nothing. when I try and hook my tv up to it via hdmi it will turn on and turn off.

And no there is no beeping at all

First off, make sure the monitor is set to detect the type of input you are using (VGA, DVI, HDMI). Make sure the power connectors are connected correctly on the motherboard, unhook power to hard drives and cdrom drives, make sure the cpu fan is connected to the cpu fan connector on the motherboard, and try one stick of RAM at a time. Go ahead and do a CMOS reset if you haven't done so already.
