Compter frozen at BIOS splash screen

[Prodigydeadeye]

Issue:

Recently I created a Win 10 installation USB to install on one of my internal hard drives. I recently switched to Linux, but wanted to have Windows as a boot option for my games. I restarted my computer, pressed F8 to choose the boot device, and selected the USB. This took me straight into my BIOS (not what I was expecting). I exited the BIOS and restarted. When I restarted, I was met with the BIOS splash screen that popups up briefly during the boot process. The issue is that now the computer gets stuck at this splash screen. My peripherals are unresponsive. I cannot press DEL or F2 to enter the BIOS. F8 doesn't work. The screen says "Please press DEL or F2 to enter the UEFI BIOS settings."

The computer has worked flawlessly since 2014 w/ no problems up until now.

 

What I have tried:

- Rebooted multiple times

- Disconnected the Win 10 installation media

- Disconnected all USB devices

- Disconnected and reconnected all SATA devices. Confirmed power cables to CPU and mobo were securely connected

- Disconnected/reconnected CMOS battery

- Checked for bent pins or swelling/burst capacitors on mobo - none

- Checked fans, CPU and case fans spin fine

- Swapped RAM with known good sticks

-Mobo has no status LEDs lit, no beeping, etc.

-Attempted to recover BIOS using a USB drive, BIOS file, & mobo manual

 

Specs:

• Intel i7 4790
• Noctua NH-U12S heatsink
• Asus H97I-Plus mini ITX motherboard
• HyperX Fury 2 x 8GB 1600Mhz
• Corsair CX 550M PSU

Try doing a BIOS flashback if your motherboard is capable of it?

It can only be flashed from within the Advanced Mode in the BIOS.

Did you try removing a critical component from boot to see if it'll give you any error? Like try booting without your ram, wait for it to fail, then install the ram back in and try rebooting.

Yes, but I saw no change in outcome

Mobo is probably bricked then. Since you can't do a BIOS flash via a usb stick, you'll probably need to RMA it...
