Great, i get home from work and find my fairly expensive dell precision machine, which i use as a web server, in some state. All three fans spinning very loudly at full power like a jet engine and the computer completely dead. When i restart the computer no characters are printed, the monitor doesn't even get off standby, no error/beep codes, nothing at all save for the insanely loud noise of the fans. It's not the memory nor any external component, and everything smells fine inside the machine (i.e. nothing burnt). This might have been caused by a power outage, judging from the blinking of my alarm clock, even though i have an expensive APC battery backup plugged into a surge protector. It sounds like a power supply problem, but before i throw any more money into this system i'd like to know if anyone has had a similar case.
