yesterday i switched from stock cooler to Hyper master 212.
It was my first time taking whole motherboard apart since you have to take everything out to get backplate on.
I should've taken pictures of the motherboard so it could be easy for me to know which wires belong where but i didn't.

after i installed the cooler, i tried to plug in the wires where they belonged
i plugged in the psu cable (24 pin one) to motherboard. Plugged in the CD drive to motherboard, (2 wires, one power and other one for reading etc) and same like this for Hard disk.
I plugged in system fan and cpu fan
I pluggedthe graphics card and it's power cord (6pin one)
There was 8 pin socket and i think it was for the cpu but i had no 8 pin wires so i put in a 4 pin one that fit it. I plug in the 2 ram sticks into their slot.
I plugged in the 2 usb cables in right place
i plugged in the power button and reset button wires as well as others such as LED in sockets where it mentioned it. i put the speaker cable (2pin) onto a 7 pin one like this ...
.... (i put that speaker cable on this one)
There is HD audio and Ac 97 audio cable but i plan to put that in later when windows actually boot up.

I press the power button and fans start aswell as graphics card since there's a small light on graphics card. Fan for PSU, system and cpu start but i don't hear any beep. It doesn't boot up.

My specs are:
Amd athlon 64x2 5000+
Nvidia 450 GTS
G7 power extreme 580W
mp-a2am-hd3 motherboard

There's only 4 pin one. no others.
 
Do you have the monitor plugged into the correct port? If that doesn't work try putting it in the onboard gpu.

You should have a 8pin but it might not be absolutely necessary. If those 4pins doesn't work can you plug it into the other 4 pins? (the notches should line up with the notch on the connector, do not put it in backwards you will fry something)

PC now boots up because i took out the first ram stick that was underneath heatsink, if heatsink and ram stick touched each other, does it cause it not to boot up?
