P8P67 Deluxe Long Black Screen (No Video or Activity) before POST

[BoneyardBrew Member]

Hello!

I own an ASUS P8P67 Deluxe and it seems to take about 8-10 seconds before I see any sign of video (monitor receiving a signal) or activity when I boot. After this delay the BIOS takes a couple of seconds to POST and then my computer boots normally. I've attempted to Google the issue but haven't found anything concrete. Is this normal? I wouldn't have guessed a UEFI motherboard would have a longer boot time than the last board I owned with a legacy BIOS.

Things I've tried so far:

• Disabling all onboard devices, the splash screen, USB 3.0 support etc.
  
• Removing all but one stick of RAM, disconnecting all of my drives + my keyboard and mouse.
  
• Updating the BIOS, clearing the CMOS, restoring default settings.
  

My system:

ASUS P8P67 Deluxe (3rd Gen)

Corsair TX650 Power Supply

Intel i5-2500K 3.3GHz

4x2GB Corsair XMS3 DDR3-1600MHz

GeForce GTX 680 2GB

Crucial M4 128GB SSD

I'm just about out of ideas and I'm hoping someone here owns the same board so we can compare times.

Thanks in advance!
