    Default PC won't stay asleep, or shutdown for more than a few seconds

    System is as below in signature. I just noticed this the other day. I don't normally shut my computer off, so I didn't notice the rest till tonight. Last week I tried to put my computer to sleep, since after I move I will be putting it in standby when not in use to save on the utility bill. The problem is that after putting it to sleep, it would wake up a few seconds later. I spent a couple hours troubleshooting this, all settings that should be turned off are off. Wake timers, disallow NIC to wake thje computer, everything.

    Command prompt and event viewer didn't know why the computer was woken up, showed "unknown" as reason for wake from low power state. I said to hell with it I'll mess with it later.

    Fast forward to today, I try to shut my computer down. And it doesn't stay off. A few seconds after it shuts down, it boots back up again by itself. I'm at a loss. I have all BIOS settings for wake on power loss or wake event disabled, wake timers in windows are disabled. I'm at a loss.

    The only thing I can maybe think of, is the PSU is faulty and it's detecting an erroneous power-on signal that doesn't actually exist from the mainboard? Can anyone provide any insight as to what might be going on here? I'm on the latest BIOS for my motherboard from MSI as well.

    Did you try unplugging the power button?

    Just tried that. No change in behavior. It turns off, and about 4-5 seconds later powers back on again.

    It's also of note that this happens if I do a proper shutdown from windows. But if I press and hold the power button, it shuts off and stays off.

    Try second PSU but I bet more on the motherboard, bad circuitry which works with the PWR On signal.

    It could also be one of your USB devices that is waking the PC from sleep. You can actually disable that for devices:

    The above tutorial takes the keyboard for example but also look under the tab 'Universal Serial Bus Controllers' tab and try disabling the devices that are listed under that tab.

    Carambola: well it would make sense for sleep, but not for turning on a PC from shut-down state.

    I have seen at least one board that supported turning on from off via USB. It was some kind of cheap thing from a Dell or something. Judging by how the keyboard I'm using at school has a "Power" key, there might be more that do.

    I'd be very upset, considering this is already the 2nd motherboard. The original one had defective PCIe circuitry causing crashing and blue screens with a gpu populated in either of the first two pcie slots.
