I have a Amilo D 1840W that won't start. After pressing the power button three of the four LED's flash for a some tenth of a second, the fans start running but otherwise there isn't anything happening.
Prior to this it could boot and starting Windows but turning itself off after a minute or two.
Someone suggested it could be overheated due to excessive dust in the cooling system. I disassembled the heating system but there wasn't that much dust in it.
So, what's wrong?
