Computer not responsive after resuming from sleep

[David Barishev]

Hey everyone,

I have been having a weird issue for a while now, which is becoming really annoying.
 

I put my PC to sleep when i'm away for a long periods of time (hour+), either manually (start button -> sleep) or automaticly as configured in Windows.

Sometimes when wake my computer especially after it's been a while - like overnight, the computer turns on (LEDs light up and fan start to spin) but I don't get any output on my display. My mouse and keyboard also don't get any power (lights turned off).

The computer doesn't response to reboot button or short press of power button and I have to kill it forcefully (long press the power button) but afterwards if I turn the computer on it boots into the same state before going to sleep (all programs open, everything is preserved).

Sometimes, after rebooting the computer I can see the old BIOS version logo and the computer is stuck before POST with short beeps with long pauses. I have to remove the GPU and reboot the computer which now boots with the new BIOS version logo, and afterwards I can return the GPU and boot fine. My Motherboard has duel BIOS so when the main BIOS is corrupted it's booting it's backup BIOS which isn't compatible with my GPU, hence the POST failure.

 

Does anyone know why the computer doesn't resume from sleep gracefully? Or why the BIOS is getting corrupted?
