hibernate

After clicking sleep or hibernate in Windows 7, my computer loads for a while and then goes into sleep mode, but not 1 second later it powers back up. The event log has no errors and no warnings appear when it comes back out of sleep/hibernation.

Here's my system specifications:

Asus P5KPL-VM
Windows 7

I believe this is all that's relevant. I've installed the latest chipset drivers, but I'm unable to update my BIOS (but this is another matter; maybe because the motherboard in the V3-P5G31 bundle is different).

I've also tried turning off the "Allow this device to wake up my computer" for the network card, keyboard, and mouse -- but this makes no difference.

If flashing the BIOS is the only thing that will fix this, then I will create a new question to this effect.

Maybe I should change the suspend mode from S3 to S1?

Why does my laptop resume immediately after suspend?
