Spontaneous Power-down

Recently developed a problem in my standby computer. It has turned itself off 2 or 3 times in the past month. Only one of these events occured in my presence, (the others were when the machine was idle). There was no warning message or anything. One minute, I was composing an email message and the next, POOF! There may have been a slight "click" sound and the machine was dead -- completely powered down! Any ideas or suggestions? This is a 4 year old Gateway. Pentium III (450MHZ), 30GB WD HDD, 384MB memory, Win 98SE. Only thing that I could think of was possibility of overheat somewhere. But the air exiting the case has always been quite cool. I'm open to suggestions. Thanks, guys!

It's the temperature of the CPU

In reply to: Spontaneous Power-down

that shuts down due to temperature. Can't judge that by feeling the exhaust air.

Open the case and clean the fans etc, make certain that they are running at full speed.

C heck and recheck...

You do have either a heat related problem or the capacitors are breaking down. Open case and blow out and clean all dust bunnies. Then, closely inspect the capactiors aren't bulging, distented, leaking or distorted. Also, verify all fans are working and then possibly route any cabling/harness for better air flow. If things settle down with case open, then likely a heat problem. If you close case and problem returns, then again check for better airflow. Also, a weaken cpu can be failing when under stress and/or other componets. Also, I wouldn't rule out a failinmg power supply at well, replace with a decent higher wattage(350W+, 400W is better) unit should you feel you want to play or save the system. The cost of replacement parts may affect your final keeping of system.

Thanks for the suggestions. As I said, this is my standby machine, which will be donated once I have my recently built one running for a while. Don't want to put much money into it. The Power supply possibility had occured to me, too. While it's possible that heat is the culprit, the fact that it's doing it while "at rest" seemed to rule that out, in my mind. Will do some further testing.
