Check RAM is seated right and in correct slots. Check CPU is seated right, and fan plugged in.

IN fact disconnect all the drives for now and just try booting it with the minimum - CPU, GPU and RAM What PSU is it?.
Tried booting with minimum made no difference all connections seem ok. It's a 420w PSU the brand is ISO. I don't think it's a power issue, somethings up with the on-board video

1134930 2010-09-06 03:30:00 What does this mean then?

Intel has introduced a new "Intel® HD Graphics" with the new generation chipsets H55 & H57. Unlike integrated graphics in the chipset, this new technology works only with a CPU with integrated GPU, such as a Clarkdale CPU. If you use an older CPU without the integrated GPU, the onboard VGA will not function as the graphical function is not present in the system. The rest of the system can still function. You will need to use an add-on VGA card for display.

New mainboards with Intel HD graphics require the dual core clarkdale which has GPU\CPU on the 1 die.
i5 Lynnfield does not and if on a P57 will be okay with on-board graphics...what chipset do you have on the mainboard?

1134932 2010-09-06 03:35:00 You are going to need a CPU that does support integrated Graphics if you want the On-board - other wise you will need to use a graphic Card , as per Speedy's link - the I5 - 750 Doesn't

Intels Site Specs (www.imagef1.net.nz) -- Almost got caught out with that the other day - The Asus P7H55-M One of these as theres several (www.imagef1.net.nz) all require the correct CPU -- note what it says in brackets in the picture
(Choose processors with Intel Graphics technology for VGA support).

The problem you may have is the onboard is trying to take over, and the graphic card wont register. BUT if the CPU doesn't support the graphics, then the card "Should" take over the job.

Do you have another PC you can try the graphic Card in to make sure its actually working ?

Yeah it's strange how the graphics card wont work. I will try it in my PC and get back to you. I'll also try the graphics card from my PC in the one I'm building and see if that works.

To clear up confusion I'm building a PC for a friend. I have my own PC which I built BUT WORKS:confused:

Okay, so really, you got the incorrect board for the cpu if you didnt want discrete graphic. P55\P57......

ASUS states your cpu should work though with the add-in gpu you have, so I would say either the PSU isnt up to much, the mainboard is faulty or the GPU....

I would do as PCT suggests, put together on a anti static pad with just cpu, ram and see if you can get the moard to post!

Well whether its the problem or not - it's crap. I'd change it to something decent.

1134936 2010-09-07 01:38:00 Update:

Removed motherboard from case put on anti-static pad, left CPU, 1 RAM module, graphics card and power connected to motherboard- turned on with no change (no beeps, no posts just CPU fan spinning and motherboard LED on).

Then removed all RAM- Received beeps regarding no RAM.

Put graphics card into working PC- Working fine

Connected PSU from faulty PC to working PC- Didn't boot, no beeps, no posts just CPU fan spinning and motherboard LED on. Thought yay problem solved PSU faulty, but no...

Connected PSU from working PC into motherboard- Again turned on with no change (no beeps, no posts just CPU fan spinning and motherboard LED on)


So what I got from all this is that the PSU and motherboard a both faulty, but what are the odds of that? As all parts are new.

I'm so confused!

Here's my specs, can you see anything that would cause conflict?

Motherboard-ASUS P7H55-M
CPU-Intel Core i5 750 socket LGA1156 Speed: 2.66Ghz
RAM-DDR3 1333 2GB CL9 x2
GPU-Sapphire Radeon HD 4350

1134937 2010-09-07 01:49:00 or , faulty psu connected to new mainboard booted and damaged new mainboard now both are dead!
are you connecting 12v and 20\24 mainboard plugs?
