I am flummoxed by an issue with my Dell XPS 410, which is about 4 years old now.
-When powering up from a cold boot, the power light comes on amber and the fans kick in loud and fast, like a plane preparing from take off.
-When this happens, I can get no video from the DVI port on my video card. If I switch to the VGA port, I get distorted video. I can restart, however, and go into Safe Mode, which seems to work OK.
I thought it was the power supply, but I have swapped it out with a new one and get the same behavior. I also tried a different graphics card, same thing...
According to Dell, the amber light means an issue with memory, expansion cards or the graphics card. I've reseated each of them (although now I think about it, I haven't tried booting without some of the memory modules) to no avail.
I've actually determined that the fan noise is coming from the CPU fan, but am not sure that that would cause all of the symptoms I'm seeing. I'm starting to think it is a motherboard issue, but I'm not sure. Any thoughts?
