Then why sometimes boot without problem? and play even games?

I think I will return the sample for a Gigabyte one.

Any luck with the Gigabyte board? So that ASUS one was a sample board and not a retail/OEM one?

I had a similar problem. The pc would run fine and then start rebooting itself. Then it would run fine for days and then start rebooting. I swapped power supplies, hard drives, video cards, etc. I had two memory dimm's and swapped them and the problem was solid. I then removed them one at a time and found that one of them was "bad". Replaced both of them and have not had spontaneous reboots for 2 years now! Sounds like you have a hardware issue.

Thank you for your reply, however my PC does not restarts, it just cannot start windows from the ITE controller sometimes, or better more than half times.

I've changed the m/b to a different one, of a different brand.

Do you know how many times I install the OS, and the rest of the software?

If you were me you would have done the same.
