Newly built PC not turning on

[mad_mike333]

Hello everyone,

before i begin here are my specs (and before you ask i have seen the sticky thread about boot/video problems)

MOBO - Gigabyte GA-P67-DS3-B3
CPU - Intel Core i7 2600k 3.4GHz
GPU - Radeon HD6950
PSU - StarTech ATX2PW530PRO 530W
RAM - Corsair 6GB, 1600MHz
Heatsink - Zalman CNPS9900
Case - Antec Three Hundred

Ok, so i connected everything together, following the MOBO manual and when i pushed the power button on my PC, i hear a small noise and nothing happens. when i press the power button again i hear nothing, i only hear that sound when i take out the kettle lead, turn the PSU switch on & off, put the lead back in the PSU and push the power on button again.

ive opened my case up to see what was happening when i turn the PC on, and it seems my CPU heatsink's fan moves slightly (for less than a second) and is then unresponsive.

Any help/feedback would be greatly appriciated. if you want to know anything else about my PC feel free to ask.

Oh and here is a video i recorded showing what happens

I think it might be a problem with the PSU, but before i go out and buy another i want to see if anyone else has had this problem.

Short?
How did the psu work before?

this is my first time buying components separetly and installing it all myself. i havent been able to test the PSU, as my family only have laptops.

just another thing as well, i plugged in a PS /2 keyboard and the light came on for a second, same as the LED on the front of my case. this is all happened very quickly though.

Edit ---- i have bought another PSU and a MOBO speaker as well. I will give an update when i test the other PSU & also if there are any beeps with the MOBO speaker too.

i have solved my problem. My PSU has a wire with 3 molex connectors AND a 4 pin connector. when i connected my fans via molex, i also plugged in the 4 pin connector into the motherboard.

As this is my first time building a computer from scratch i assumed the 4 pin connector was to be plugged into the motherboard system fan slot.

when i took the 4 pin connector out, the system successfully booted. So it turned out it wasnt a PSU problem at all, just a connection problem.

Hope this helps anyone experiencing the same problem.

Just be glad you didn't break anything, IIRC we just recently had another poster who did the same and fried his system.
