Is This a Cooling Problem, Power Supply, or Something Else??
Hey guys,
I just built a new PC and it is giving me power issue problems. It ran perfectly for a week, but then it shut off automatically last night. I turned the power supply switch off and back on. The motherboard LED light came on, but the machine would not boot up when I pressed the case power button. I waited 15 minutes, unplugged the power and plugged it back in. As soon as I turned the power on from the power supply, everything boots up for a second, and then dies down. I clicked the case power switch, and it maintained a stable boot and operated Windows normally. However after two hours of use, I turned off the computer. I tried to turn it back on, and it was dead again. I really don't think the problem is a bad component or periperal. Otherwise, the computer would never boot back up. I suspect that it may be a cooling issue. I checked my BIOS and the CPU temp ran up to 68C. I purchased a Intel Pentium D 2.66, and the reviews do mention that it runs hot with the stock heatsink. Does these symptoms sound like a heating issue, or perhaps a fault power supply? I don't have my specs with me right now. Thanks! |

Damned things go bad at the slightest excuse. That's why I always have at least one or two spare *known good* power-supplies on hand. I also have a PS checker that tells me if a supply is completely dead. Hmmm ... Thinking about it: I should have picked up another one, last time I was down at COMP-USA, when they had those real nice ones on sale. Damn. In any case, buying an extra power-supply, even if it isn't the problem, is never a mistake; and is pretty much cheaper than any of the other replacements. Still: You might check *real good* to be sure your CPU has good connection to its heatsink. Mounting one wrong, without good thermal-compound, cocked, backwards, or other ways of not getting good connection, can cause all sorts of problems when it overheats. -- _____ / ' / â„¢ ,-/-, __ __. ____ /_ (_/ / (_(_/|_/ / _/ _ |

It sounds like you have a bad PSU, most likely.

'System' is more than just a power supply. Every answer will be wild speculation until you provide some useful numbers. In but two minutes, those numbers can be obtained using a procedure in "When your computer dies without warning....." starting 6 Feb 2007 in the newsgroup alt.windows-xp at: http://tinyurl.com/yvf9vh In your case, those numbers would be particularly informative both when system is working normally AND when it tends not to start. |

I didn't know what to look for, only that 5V and 12V were OK under load. Peter. -- Peter. If you can do it today, you didn't put off enough yesterday. |
