Hi Guyz,

I recently bought new pc parts from a popular online S.A retailer company I assmbled a new pc the parts are as follows.

Intel I5 3750k
Z77-D3H gigabyte board http://www.newegg.com/Product/Product.aspx?Item=N82E16813128543
Cosair Vengence 1600MHZ http://www.newegg.com/Product/Product.aspx?Item=N82E16820233218
No Graphics card
2tb western digital hardrive
Cx600 cosair power supply http://www.newegg.com/Product/Product.aspx?Item=N82E16817139028
GMC-H80 chasis http://www.techpowerup.com/reviews/GMC/H-80/

I assmebled all the parts and very excited only to find out that nothing boots up.

I made sure the 24pin is firmly plugged in and the 4pin in the board is firmly plugged in as well.

Still nothing seemed to bbot up. Then eventually the pc went on for 2 seconds literally and switched off. Then I attempted again and it was dead.

I did the papaerclip test according to the website with one of the chasis fans and it span worked no problem.

I returned the power supply to the online retail compnay they said its fine.

Then I returned the CPU and motherboard and they confirmed it is fine as well I have asked them what happend when they tested it and I go no answer.

I have not tested the board with another power supply yet.

I Attempted to take the board out put in a solid surface (kitchen counter) plugged in the power supply connected the power inputs to the board still nothing happends.

I switched the power cable with the rest cable still nothing happebnd no beep of the speaker as well. It just reamins dead.
:cry:
Im not sure what the issure could be as I removed the hardrive and the ram and still no repsonse.

The motherboard is not touching the chasis as well when after I have assembled it.

Im not sure what the issue could be ? Is it the board, the cpu or the PSU that is still the issue and the S.A online retailer has told me they are all fine

The wallsocket I checked tried another socket as well even tested the wall socket and the power cable still nothing when I switch the pc on.

Do you guys think it is a compatibility issue perhaps or a voltage input or output issue?

Im not sure what to do extremeley disapointed please help guys.
 
One of these must be the culprit - mobo, CPU, PSU, RAM
PSU sounds good since it powers the fans. Jury is still out on the rest
Have you tried with only one RAM stick? Also try with a known working RAM stick if you've got one.

9/10 times when a client brings us a machine and its doing that its the PSU or Mobo, ram gives issues very seldom and i have not had a single faulty CPU in the last 4 years come in.

in your case the easiest thing to try is another supply even if it does power on that does not mean the voltage supplied is correct.

Is it known to be working? Built a PC maybe a month ago - no boot, swapped RAM, then all was good. If its not that, then we can at least establish that the retailer didnt check something properly and go from there.
 
I'd wager its the PSU. The fans could be powered from a different rail when its actually the 12v rail which the PSU that is dead.

I managed to wiggle the power supply it went on and off again for about two seconds.

I think the best bet is too take it into a store and ask them to test it with another power supply to determine if its the MB or the PSU. Il stand there when they do it I need to see if it works or not.

How would I know if the voltage is correct or not how do I check this? Its a Z77-D3H board and a Cosair600mhz?

Multimeter. I think you can allow a 1V variance before things get dodgy
