The interior is very clean. And the fan is working...

Hum... doesn't seems to be a common problem. Did you try with another video cable and/or another monitor (tv set) ?

... it's a stupid option because if the dc shut down really, i don't think it's the video cable, but ...

check power supply for correct voltage

to be honest, if this was 5 years ago, i would have said take it back to the "seller". but now you can get them extremely cheap. perhaps buy another DC unit and test that with your other one?

Sometimes, in addition to cleaning the pins you need to make sure they make contact properly with the part you take off. Lightly bending them in a bit may ensure a decent connection. Please don't bend a lot though, just a firm push should be enough.

This is mentioned in the same tutorial linked to earleir though.

This may not help though if your problem lies elsewhere.

my computer did the same thing your dreamcast is doing and it was becuase the fan wasnt working properly. so like most people said, its prolly overheating

open the console its real easy, to the left of the gd rom drive is the power board unscrew it and gently lift it out. clean it finely with a psp cloth or similar and be sure to clean the pins too then reassemble. you have to do this every couple of months due to the poor cooling in the dreamcast and the amount of dust that quickly gathers.
