New Computer Won't Start!

[shicx1]

Hi, I finally built my new comp after 2 weeks of waiting for my case which had to be replaced cause it was defective. When I try to start the computer, nothing happens at all! The "DRAM Power LED" and "Standby Power LED" are on. I had to leave all the parts in a box covered with newspaper on top for 2 weeks cause I was waiting for my new case to arrive. Btw, this is my first time building a comp, so maybe I did something wrong that alot of first timers do.

Sounds like you might have hooked up the cases momentary switch wrong...

No fans or anything turn on? Its goota be something with the switch and or power supply....something should happen if those are hooked up correctly

Yah ur right, I hooked it up wrong, now it turns on, but it sort of starts up. The little fan on the motherboard is spinning, but the fan on the PSU and CPU look like they cant start up. Someone on another forum says I need 480W.

I think that might be splitting hairs, you've got 450 watts.
Could some of the other case wires be hooked up wrong?
Maybe you should unplug as much as possible & add things back 1 at a time.

does the bios/CPU/PSU have some sort of quiet fan feature? is the 12V 4 pin to the motherboard connected? do you hear any beeps from the speaker connected to the motherboard? try removing the video card and see if fans power up.

did you forget to plug in the extra 4pin power connector to the motherboard? I see that a lot...
