Hello,

So my problem is a bit odd (at least to me, I've never had a mobo behave this way before).

I have a system running a Gigabyte GA-B85M-HD3 mobo, an i5-4430, and a GTX 660. Today while browsing the internet, my computer crashed (power off completely). It was afterwards unresponsive to the power button. However, after ~10 minutes it spontaneously booted and said I had corrupt bios, and reflashed backup bios via dual flash. Now, the computer is working (I am typing from it now) but it is behaving rather strangely:

It is sometimes unresponsive to power button input, instead booting ~4-5 minutes after the button is pressed. When it is restarted via software (or sometimes when it is powered on from cold) it takes about 30 seconds to boot up to the gigabyte POST screen.

However, the computer once it gets to this point seems to be performing fine in Linux, Windows 7 and OS X...

Any ideas? So far, I have updated to latest BIOS via QFlash (i have read @BIOS is not so great) and have replaced the battery on the mobo.

Any help would be appreciated, thanks :)

I set up everything as I normally would, the only thing I normally change is a setting on how to treat legacy USB devices (I forget exactly what it's called) in order to circumvent a problem with chameleon bootloader. Other than that, and sometimes fiddling with fan speeds, everything is optimized defaults and has never caused issue with my system before.

I have also tried booting without that setting enabled and the problem persists (the only reason I change it to treat legacy devices as floppy is to get rid of this annoying message with the bootloader)

So, the delay seems to be a permanent thing now... I haven't been using my PC for the last few days, but today I noticed there is frequently a marked delay between pressing power/waking from sleep (true sleep, not the hybrid thing on Windows) of around 5-10 minutes.... This computer is not really usable in this condition, does anybody have any ideas I could try to fix this issue? Any help would still be greatly appreciated, thanks.

I think it might be a software problem. I always turn off all the sleep modes in advanced power settings. Windows sleep modes have always been problematic, IMO. My computers are either off or on and I sure do not leave a comp on over night or when I am not around. Unless downloading an extremely large amount of data that I know will take a while.

Erm, I really appreciate the help, but I don't think you understand the problem. The computer will not power on when I push the button. What I meant is that this happens both when it is being turned on cold (like if I unplug it from the wall, plug it in, and turn it on) AND if it is sleeping (as in actually putting the CPU into the sleep state, not anything to do with software such as Windows Hybrid Sleep).

I apologize if my wording was confusing, but unless I am missing something I have no idea how a computer not responding for 5-10 minutes to physically push the power button could be a software issue... The PC will not emit a beep code, power on LEDs/fans or anything for this 5-10 minute time period, and has certainly not booted into an OS when powered on cold.

Thanks for the response. Nothing happens differently when I push and hold the power button. The machine still will not respond, and will turn on instead 5-10 minutes later.

Thanks for the advice, but when I turn it on from cold it is definitely not asleep, the bios flashes and runs all checks, and the bootloader runs and boots either os, not resuming.

I have also tried cutting power completely to the machine for a few minutes to ensure it is off, then powering on, with the same results so I am fairly positive it is not sleeping.
