Hello,
We have a problem with an old SGI. The SGI, type Fuel, boots ordinarily. However, after about 15 minutes a grey window on a blue screen pops up whithout any other warning, which states "The system is shutting down". Afterwards, the computer actually shuts down. During operation, a fan is runnig with a rattling noise. Thus, we think the reason for the shut down is a overheating of the system. Does anyone have an idea, what to do in this case?
