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!

      Tim Cook: "The US over time began to stop having as many vocational kinds of skills." What's the point of wasting time getting those skills if you can't get a job with them? Good Lord, maybe he and his cohort of CEO's who exported all these jobs to China should just shut the f**k up :D

    • Microsoft Opens Fairwater: Wisconsin AI Campus Runs as One Supercomputer via 800G Ethernet

      By +TRS-80 · Posted

      Closed-loop cooling and a custom 800G network protocol let the $7.3B campus run as one AI training machine. Microsoft confirmed June 23, 2026, that its Fairwater campus in Mount Pleasant, Wisconsin, is fully operational — and the engineering behind it makes the facility something fundamentally different from every data center that came before it. Where conventional cloud infrastructure racks up general-purpose servers and parcels out workloads to each one independently, Fairwater links hundreds of thousands of NVIDIA GB200 Blackwell GPUs into a single, coherent cluster using a two-story building design, 800-gigabit-per-second Ethernet fabric, and a proprietary networking protocol co-developed with OpenAI and NVIDIA. The result, according to Microsoft, is the closest thing to a purpose-built AI supercomputer that any company has ever placed in commercial operation. https://www.techtimes.com/articles/319205/20260627/microsoft-opens-fairwater-wisconsin-ai-campus-runs-one-supercomputer-via-800g-ethernet.htm
