Problems with random power offs

  1. I recently put together the machine below, but im experiencing random shut downs where the power drops completely on it.

    The specs of the machine

    MSI K9N SLI-2F
    AMD Athlon 64 X2 5600+ 2.8GHz Socket AM2
    Corsair TWIN2X 5400 DDR2, 2048MB
    BFG GeForce 8800GTS OC2 320MB
    Cooler Master Real Power 550W
    Seagate 320 GB IDE HD
    Maxtor 250GB IDE HD
    Seagate 250 GB SATA HD
    2 x Wester Digital Caviar 250GB SATA HD

    I thought at first it may be overheating but I've been running MSI's system monitor for the last while and even while doing heavy processing the system temperature has been a fairly steady 33 degrees and the cpu at 42 degrees. The voltage across all three rails also seems to be fairly stable. I've also run memtest in case it was the ram and it returned no errors. I thought it might be the PSU but the PSU worked fine on the system below prior to upgrade.

    *MSI K8N NEO4-FI
    *AMD Athlon 64 X2 3800+ 2.0GHz Socket 939
    *2x OCZ GOLD GX XTC DDR PC3200 1024MB
    *Sapphire Radeon X1800GTO 256MB
    *CoolerMaster RealPower 550w +3/+12/+12

    IDE00 - Seagate Barracuda 320GB IDE
    IDE01 - Maxtor Diamondmax 250GB IDE
    IDE10 - NEC DVD Recorder
    IDE11 - Maxtor Diamondmax 250GB IDE

    SATA 1 - Western Digital Caviar 250GB SATA
    SATA 2 - Western Digital Caviar 250GB SATA
    SATA 3 - Seagate Barracuda 200GB SATA

    The only real difference are (in terms of power consumption) I believe the Geforce 8800gts vs the ati x1800 and the faster cpu.

    If anyone has any suggestions on what may be causing the problem or how to resolve it I would greatly appreciate it.

    Check the CPU temp monitoring settings in the bios... Make sure these settings are correct, and not set to too low of a shutoff temp. Make sure the CPU's heatsink is properly installed, the fan is running to speed and thermal compound is applied properly
