Hi guys,
I bough on Ebay a "used once" Mobo, P67A-UD3P-B3.
It looks brand new and basically un-touched. I got myself a New Intel 1155 CPU and 4 New 8 Gb ram sticks.
Also I got a BIG Gelid Tranquilo cooler. PSU 700 w.
When all assemble (just the most needed basics, 24 pins power+8 pins cpu power. 1 hard drive and 1 CD-DVD)

I fired up the Mobo and ............................Fans started, lights came on. It ran few seconds then stop. All dead !
then restarted then stopped again and so on ! I also noticed, the CPU fan runs very slowly.

My question : is that Mobo dead ?

Make sure you have the latest bios installed. Some P67 boards had that issue.

Uh
How do you install any BIO if the thing don't even run light up

Without knowing the details of the hardware you are using all we can do is guess as to what the problem is.

As TFisher has suggested, the first thing to consider is the BIOS but you are now in a position where you may need the latest BIOS to run your CPU and you can only update the BIOS if you have a CPU that is being recognised. Without knowing which CPU, you are trying to run, we can't say if this is the cause of the issue you are facing.

If it turns out that the CPU is not being recognised then you need to either buy a cheap one that will be recognised by the earliest BIOS version of the motherboard, find a friend who has a a supported chip and who will let you borrow it to do the BIOS flash, find a friendly PC shop who can do the update for you (this will usually cost) or contact Gigabyte Technical Support here: http://ggts.gigabyte.com/tech.asp?ClassID=2&Country=U.K.&SourceWeb=B2C and see if you can arrange for them to update/check the motherboard for you.

Thank for trying to help.
My CPU is : Intel i5 3330S Quad Core 2.7GHz 6M SRORR LGA 1155
My RAMS are : 4x 8GB DDR3 PC3-12800 1600MHz DIMM C10 Blue Heatspreaders.

And I have the strong feeling Gigabyte Mobos are not good news when I see how many posts (problems) people have with them.
Better stick to Asus or As Rock, I guess !
