A client's server shut itself off today with the fans running at high speed and both internal system health and External system health leds blinking red. The machine has a single Pentium P4, 3Gig processor and a single power supply. There is no sign of overheating anywhere in the machine but the room in which it lives was at 76 degrees Fahrenheit. Shutting down and restarting brought it back up but it shut down again about 2 hours later and now shuts down after a few minutes. I'm going to have to build them a new server overnight with a spare Fujitsu Seimens machine I have, but I need to get this machine diagnosed and repaired asap.
What should I be looking at? And what software tools can I use?
I'm putting a lot of points on this because the situation is critical and I cannot find anything that describes these symptoms on the HP websites.
