Ok, so I am working on this Dell Dimension 8400. The fan goes full power, and no boot. After replacing the fan, still does it. It appears to be a heatsink problem. A very common problem on the Dimension 8400 from what I’ve read. The heatsink doesn’t make great contact with the processor (how it knows that, I don’t know). Anyway, while playing with it, I noticed that the computer will boot if the heatsink is tilted to one side. So I had to make that permanent. This is the ONLY way I have found to get it working without replacing the heatsink and motherboard, and possibly the CPU. I know it has “hack” written all over it, but oh well. It works, and I’d call it “creative” ;-)
