Computer wont turn on [pictures]

[willclarke]

I have been building my new computer for the past few hours but i got stuck plugging everything in. Everything seems to be plugged in but it wont power on . Can any experts tell me what i am doing wrong?

I am using
P7P55D LE motherboard
5850 Graphics card
westerdigital 500Gb hard drive
550w corsair psu
haf 922 case
i5 750 CPU + heatsink
2x2Gb g.skill ram


RAM installed in to dual channel slots

CPU + Stock heat sink, installed in to 4pin socket labelled CPU fan.

Graphics card, 2 6 pin PCI have been plugged in.

Optical drive - installed in motherboard and powersupply. No idea what the 7pin at end does i do not have anything that fits.

Hard drive - i recycled from my older computer so no instructions on installation.

Wires from back

is there an LED lit on the motherboard?

also, did u turn on the switch on the psu (sometimes there is / isnt one)

Any activity from the fans or power lights

Argh at the huge slightly out of focus pics.

Okay basic checks:

Is the 12V ATX 4 pin / 8 pin connected? (can't see it in any of the pics)
Is the power supply switched on? (I've done this before)
Try with only 1 RAM stick in (could be one of them is dead).

check the small wires from the power switch, reset switch that join to the mobo. could be you got them in the wrong slots?? some led pins too - you getting any signs of life at all?

no ledon motherboard, i plugged the 20 pin connector in but cnanot find the 4 pin one

On the very far right of this pic there is a blue 4 pin connector, above the blue heatsink, have you got that plugged in?

 

[stulid]

I can just make it out in your top picture, nothing plugged in!

 

[willclarke]

no but i have a 8 pin connector not a 4 pin. how do i plug it in?

 

[stulid]

Pull the plastic cover off the other four pins.

You sure you not got a four pin?

 

[willclarke]

im certain yeah

 

[UKDTweak]

Looks like the 4 pin is not connected...

Plug the centre 4 of the 8 pin into the 4 pin socket, same thing

 

[PhillyDee]

There may be 2 8 pin connectors. Select the one that fits.

Remove the black plastic cover from the motherboard socket and place in there.
Or: The 8 pin will also come to bits in to 2 blocks of 4. One half will plug into the socket with the black cover still in place.

plugged 8 pin in but still not working

 

[willclarke]

one 8 pin was 6 + 2 and is now in grphics card. I plugged the middle 4 of the 8 pin to the 4 pin socket

Have you got any spare power leads you could try? It could actually be the fuse in the plug has blown.

Same board i have by the looks of it, or similar. make sure you have plugged in the 2 power connectors into the motherboard. one next to the memory, the other above the cooler. by the picutre you can just about see the one above the cooler isnt plugged in, therefore stopping the boot up.

 

[stulid]

Have you removed the plastic cover?

Not sure how you fit the middle pair of a 8pin into your connector without mounting sideways?

 

[MonkeykingZX]

can you take a pic of how you've plugged the 8 pin in?
