  1. SPECS:
    Asus A7N8X
    AMD xp3000+
    1gb Corsair PC3200 XMS LL
    ATI 9800 pro ? Geforce 7800 GS OC
    Maxtor 120gb SATA
    Antek TruePower 480
    Audigy 2

    Problem History:
    Computer began restarting during active periods in windows over a week ago.
    3dmark 03, 05, and 06 all freeze during load of or near start of tests
    (tests sometimes render normally for 20 sec before freezing)
    -Causes non-recoverable crash, no error reporting, PSU must flipped

    -Windows was reformatted and the ATI 9800 was upgraded to an AGP Geforce 7800 GS OC.

    - All drivers are up to date, bios up to date, mobo drivers up to date, raid as well
    - windows is also fully updated

    -Tried multiple driver versions for raid, and many graphics drivers
    - Still getting random restarts every hour or so and 3dmark has same problem.

    -Ram was checked using windows ram diag and mem86 (5 passes)
    - errors found under two tests (10ish total)
    -isolated sticks via removing one at a time
    -one stick found to be the only one defective
    -booted computer with the good piece of ram and tried 3dmark 03, and 05
    -this failed as usual and my computer still restarts when in windows
    - tried installing a game (F.E.A.R) to test but could not finish without restart

    -The ram sectors that are not matching are not the cause since the computer was booted with the single stick of good ram and problem persisted.
    -PSU could be the problem? Rails under PC Probe look tight however…

    Any suggestions would be greatly appreciated!. Thanks for all of your help.

    1. check ram with memtest 86+ for at least 7 passes.
    2. PSU is most likely the culprit.
