    I have a similar problem with my board, and if I leave the comptuer on, in Vista and it goes into sleep for awhile it'll turn itself off and then when I try to get it back on it'll do this boot looping.

    Also when I try and overclock it sometimes too far and switch settings in bios, when I go to change the settings to something different and it goes to reboot it'll go into the loop.

    I'll take off legacy USB support and see if that helps.

    I have same problem with like reboot over and over, I thought it's bad ram but turn out bad CPU !!!, yes I did try use other CPU one is celeron 420 works, other one I just bought E1200 backup cpu works fine while my E7200 is on the way to rma dept.

    What version BIOS do you have on rev 1.1 ? mine are F4

    If your bios is older than mine, I guess you could try flash F4 or F5 if it
    help.

    Try reapply thermal paste (arctic 5) and secure it all 4 push-in pin all the way down.

    remove all devices but cpu, vid card, one working ram to plug on slot 1 or slot 3.

    boot up into bios then hit load defaults then save to exit.

    (sometimes cmos battery can cause problem, won't save bios setting or reboot, also cmos battery dies at warehouse being sitting on shelves before it shipping out).

    if no help, try use different CPU and see what happen.

    I don't have another cpu lying around to try and I'm not going to buy one just for testing purposes. If I stopped trying to tweak the overclock then it would be generally fine, as long as I could get it to properly deep sleep/hibernate, as that's the only time at present it would come up.

    I am thinking it may be my video card, but not sure.

    WHAT??? Are you crazy? No offense meant, but yes you must have ram in the system for it to turn on at all

    Please test this ram in another PC or your's if you can one stick at a time >>>

    I am having a similar problem but... if I run everything at stock speeds and all set to auto, S3 sleep works and the PC will wake up without issue. If I try to OC (8x400) I get into the loop.
    CPU- q6600
    Mem- G-Skill DDRII 800 CL5-5-5-15 1.8-1.9v 4pcs of 2gb each.
    Would you please populate all of the fields below with what I should try in the bios with this CPU and mem combination.
    Thank you in advance for any assistance you may provide.

    Same issue here. When resuming from Standby (S3) computer will start up and go into the reboot loop. Doesn't even stay up long enough for anything to appear on screen. Holding out for a BIOS fix.

    But does it work with stock (not OC'd) settings?
    I am of the mind that if it works stock but not OCd then I am missing something in setting up the OC.

    resolved my issue this afternoon.
    I went back to all stock and it will resume from S3 without issue.
    Target OC was 3.2 so I tried 9*355=3.195 instead of 8*400=3.2
    I tried leaving the multiplier at 9x and set the CPU host freq to 355
    PCI exp freq to 100
    MCH Freg Latch to 333
    Sys mem multiplier to 2.4B (memory running at 852)
    everything else is set to auto.
    I didn't touch the memory settings.
    I am now able to resume from S3 sleep without the boot loop
    F5 bios
