I have a Dell E310 that is not quite 2 years old. In December, it would not power up. Only a flashing yellow light. The diagnosis said that it was either a power supply problem or a faulty system (mother) board. I took the machine to a local repair guy and he told me the same thing (for $30!). So I figured, I can change parts as good as the next guy. So I ordered a new power supply from Discountelectronics.com. I installed the new power supply and nothing changed. The cooling fan starts to turn and then stops, and I am still getting the blinking yellow light. One thing that is different is that the Power Supply fan now begins to turn, but it also stops. So I called Dell and ordered a refurbished motherboard. When it arrived, I installed it, took the memory sticks and CPU from my old motherboard and istalled them on the new board hoping this would take care of the problem. Still, a freekin blinking yellow light. Last night I read somewhere that sometimes a USB connector will become shorted or bent causeing a power issue which results in the blinking yellow light. So I checked the front USB's and everything seems ok. I pulled the board that the front switch and USB's are located and did a visual inspection and nothing seemed burned or distorted. I'm about out of ideas, considering there is not much left in the machine that I haven't checked out or replaced. When the whole mess started, there was a rather large dust bunny in front of the CPU cooling fan. I have been trying to find out if the cooling fan doesn't work, maybe a failsafe prevents a power up. I don't know, at this point I am about out of ideas. Any help would be greatly appreciatred.
