Newly Built Computer Won't Stay On
I just built a new computer, and when I turn it on, it turns off in about 4
seconds. I hear a longish beep, and all 4 fans in the system are turning before the whole thing shuts down. There is no time for anything to show up on the monitor. The system is as follows: CASE - COOMAS|CAC-T05-UB BLK/BL RT PSU - SUNBEAM|SUNNU450-US-BK 450W RT MB - ASUS M2N-MX GF6100 AM2 CPU - AMD|A64 X2 3800+ AM2 2x512K R MEM - 1G|OCZ DII800 OCZ2P800LP1G R HD - 120G|WD 7K 8M SATA2 WD1200JS The Power supply has this temp monitor fan controller thing, and it shows a temp of about 25 C, before the computer shuts down. I've tried starting with the knob at high, low, and auto, with the same results, that is shut down in about 4 seconds. I tried to boot before I installed the drives, and got the same results. Any help will be greatly appreciated. Thanks, Jack |

Thanks, Jack ----------------------------------------------- That particular DDR2-800 memory needs 2.2V and is geared more towards overclockers, but I believe that motherboard supplies a maximum of 2.0V to the memory and is not the best board choice for high voltage memory. Your memory is probably not supported, so I'd go to the Asus site to get a list of QVL memory for that motherboard, then do a memory exchange. if you can get your hands on some DDR2-533 1.8V memory just to see if it'll boot up, that could rule out other possibilities. Also, double-check that both 12V power cords are plugged into the motherboard. -Russell http://tastycomputers.com |

What I'm seeing on the Anandtech forum is that (variants of)this MB are causing LOTS of headaches, with regard to low RAM voltages in particular. Though AMD did put together a good rig using the M2NBP-VM CSM mated with the NVIDIA Quadro NVS 210S + nForce 430, it (the M2N) seems awful damn touchy about which components it's mated with. I haven't checked on whether the suffix on the board model means a lot. My opinion, which is affected by low intellect and bad upbringing, is that the ASUS MN2 board is more headaches than it's worth($100); probably more trouble than the time you'll spend getting it to work right. Maybe more experienced types can suggest something other than this nuclear option. http://avs.amd.com/Home-Page/Best-of...m-Provide.aspx ~best luck |

Might be defective, might be powering defective parts, or a general system build error has shorted something (doubtful since it stays on 4 seconds). The PSU might be checked with a multimeter, monitored right up until the point of shutdown. 2) Motherboard cause, either bios sensor reading out of range (like voltage or fan RPM), or hardware shutdown like CPU temp (particularly if heatsink isn't making contact- a merely marginal heatsink installation wouldn't be bad enough to hit overheat threshold within 4 seconds from cold-off state, it'd have to be removed and the interface inspected to determine this as 4 seconds isn't likely enough time to get to the bios health monitor page to see any readings. |

Since nobody else has mentioned it, I'll toss this out. Double-check your wiring job in regard to the power-on and reset buttons and motherboard pins. Your magic 4 second delay is exactly the effect you would get if power-off were being held down. Bob |

I know on some of them, it was not clear which way they should go on. Jack |

When the NFORCE430 and P965/G965 chipsets were first released, I had problems with some custom builds, whereby the system wouldn't reach a POST screen, but symptomatically power on, then power off in a never-ending cycle every 3-4 seconds until memory was exchanged for more compatible sticks, immediately solving the issue with no other component or settings changes. Since the OP was mentioning identical symptoms, and is using memory out-of-spec for his board, I suspect memory being the culprit. Russell http://tastycomputers.com |
