Computer turns on, then turns off one second later.

Roughly 2 weeks ago, I bought a list of components for my new build. A week later, I put my new build together. When I pressed the power button, the computer would boot up for about one second before turning off, it would keep trying to boot every 3 seconds until I turn off my PSU. I searched the internet and was advised to take out every component one by one until I was left with the motherboard, CPU, CPU fan, power supply and case (with the power button wire plugged in), I did, and it still wouldn't boot. There was this one time however where all the fans remained on, I didn't know whether it had actually booted into the BIOS because I didn't have it plugged into a monitor, but all the fans, including the CPU fan, were running at full blast.

I sent the PC off to a friend of ours, a very experienced technician. He narrowed the problem down to a broken motherboard or CPU, either because they were DOA, physical damaged or killed with static, but he didn't have any 1155 socket motherboards or CPU's to confirm which one was broken. I was very gentle with the components and I don't I killed them with static, I didn't feel any shocks or hear any clicks, I worked on laminate flooring, I have as much hair as Bruce Willis and I didn't wear baggy or fluffy clothing. While I didn't use any fancy equipment or techniques to ground myself, I did regularly touch the metal door handles and metal framing of my conservatory.

I decided to take a gamble and return the motherboard to eBuyer and call their customer services to explain my situation. The guy on the phone pointed out that I had bought an Ivy Bridge processor just 2 weeks after launch and that the motherboard may not have the BIOS update to support the new architecture. The guy one the phone was pretty certain that it was a BIOS / CPU incompatability issue and suggested that I should obtain a Sandy Bridge processor from friends or computer specialists to update the BIOS (something I don't think I can do). Our technician friend wasn't as convinced but said it was a possibility.

My specs are:

CPU - Intel Core i5 3450 Ivy Bridge @ 3.1Ghz

(Both ordered together on 16th May)

RAM - Corsair 2 x 4GB @ 1333Mhz
PSU - OCZ silent something 500w
Case - Casecom 6788
GPU - Sapphire Radeon HD 5770 Vapor-X

Are there any particular symptoms that could diagnose which component is at fault and why?
Is it possible that I killed something with static?
How likely is it that the Ivy Bridge processor is incompatible with the motherboard and what can I do fix that?

I've been tempted to buy a mid-range Z77 board, it will be future proof, it won't be incompatible with the Ivy Bridge processors and most importantly it should work as long as the CPU isn't at fault. It will be the quickest solution as this is causing me a lot of stress, I'm becoming impatient and it's a huge distraction, I can always sell or try to return the Asus H61 at a later date.

Thanks in advance, Brennan. :hello:

  1. I've gone through that list many times for the past 2 weeks, I've narrowed it down but it's too vague to pin point the problem and I'll need to fork out at least £100 to find it. I was hoping someone would be able to help me and find the problem by looking at my specific symptoms and specs.
