K8N Neo4 Platinum - random system power off
« on: 03-April-05, 23:35:26 »

Hello, i have the following Problem:
When i run my favorite video game, after some minutes my computer suddenly powers off. The Power Led is blinking in approx. 3 second period. I am not able to restart the computer until i completely switch off power (by either the switch on the power supply or removing the power chord). When the computer gets into this state, it will power off again, quite quickly, on any attempt to reboot (even after completely powering down).
According to CoreCenter, and after trying the game in windowed mode, my CPU temp. never exceeded 47 degree C.

My setup is as follows:
MSI K8N Neo4 Platinum
AMD64 3500 (winchester)
takeMS 1Gig CL2,5 RAM (one module installed in slot 0)
BeQuit 450W power supply
Thermaltake Silent Boost K8 heat sink

any ideas/similar experience?

  • hi tomfromrom ,
    welcome to the forum. :yes:

    1) If it's a memory error the pc usually reboots. You can test your memory with Memtest86+
    2) What's the amps on the BeQuit 450W power supply. this is uasually shown on the side of the unit as Max Output 3.3v=??A, 5v=??A, 12v =??A.  Can you provide this info please.
    3) What Os & Update are you using.
    4) Are your Drivers upto date (Downloaded from Nvidia.

    luck :smile:

    Sounds like a PSU that is too weak to me. The give away is the blinking Power LED along with the need to completely remove power before it wants to restart. How many AMPS are on the 12v rail of that unit? You can find that info on the sticker on the PSU. As I remember BeQuiets have a rather weak 12v rail and our systems require a strong 12v rail.

  • Given that it heppens during gaming, it could be a video card issue.  Have you checked to see how hot your GPU is getting (right click the desktop -> Properties -> Settings -> Advanced -> Geforce 6600GT -> Temperature settings)?  Download the program available at and run it with the temperature monitoring window next to it.  If the temp goes much above 90, then your video card is probably getting too hot and causing the system to crash.  

    Your CPU temp is good, but are you running overclocked or at stock speeds?

    Some additional informations:
    the power supply is a BeQuit BQT-P4 450W S1.3
    +3.3V-28A +5V-45A +12V-22A -12V-1A -5V-0.8A

    Windows XP Professional SP2 with all current patches from Windows Update
    All Drivers updated by MSI LiveUpdate (including the NVIDIA VGA Driver), to the current versions, as of April, 2nd
    (can't check the version numbers as i'm currently at work).
    I've disabled the FDC controller (as i've got no floppy drive), the raid controller (SATA 5-8), and the serial & parallel ports.
    All BIOS settings 'conservative' (no overclocking applied, all timings/Voltages set to automatic).

    To reiterate, the system does not reboot or freeze - just powers off, with the power led start blinking (as if it went to suspend mode).

    BTW what's the expected/safe working temperature range for the AMD64 Winchester CPU? What's the max temp. the Health Status should display?

    Thx for your answers.

  • Hi tomfromrom,
    Thanks for the extra info.
    just powers off, with the power led start blinking (as if it went to suspend mode).
    Does sound like a power supply issue.
    Your effectively running with only 3/4 of the recomended 12v amps. see
    Temps are idle 36C load 54C. Maximum per AMD = 65C.

    I'd be inclined to use the Nvidia site for your drivers, MSI ive  update is useful for any of the mSI Software you may use & bios updates.

  • Hi tomfromrom, I saw that you posted on my random shutdowns PS2 keyboard thread...

    Do you mean to say that by changing keyboard model you have cured your random shutdown behaviour?

    I am wondering because its important that we know if the same problems occur on the K8N Neo 4 (I.e. the problem is not fixed yet)...
