You might be right, but mine also seem to be a bit early, because...
I found the problem. And: the LEDs could be right, it IS the motherboard! Yesterday I tried almost all you told me. Except getting off the CPU cooler. But nothing helped. And I thought: maybe there really is something bad? So I searched for any damages on the mainboard. And: I found one.
After searching with a magnifier I found a scratch. It could happen during the opening of the case. This scratch cuts a slightly bigger and a very small circuit path...
It seems to be my fault, now back to the question: is dell selling the board only? To endusers? Should I ask the support?
