Hi @ED12041 

Welcome to the HP Support Community! We're here to help you get back up and running.

I understand the concern. Based on the details provided for your OMEN Transcend 14-fb0000 showing CMOS Reset (502), intermittent gray screen, black screen with fans running, and a frozen cursor on the restart screen, the behavior may be related to BIOS initialization, CMOS settings, or startup hardware detection.

Please try the following troubleshooting steps:

Perform a hard reset:

• Power off the notebook.
• Disconnect the AC adapter.
• Press and hold the Power button for 15-20 seconds.
• Reconnect the adapter and power on the system.

Restore BIOS defaults:

• Turn on the notebook and repeatedly tap Esc.
• Select F10 BIOS Setup.
• Press F9 to load BIOS default settings.
• Press F10 to save and exit.

Run HP Hardware Diagnostics:

• Power on the notebook and repeatedly tap Esc.
• Select F2 System Diagnostics.
• Run:
  • System Tests
  • Memory Test
  • Storage Test
• Note any failure IDs that may appear.

Perform BIOS recovery:

• Turn off the notebook.
• Press and hold Windows + B.
• While holding the keys, press and hold the Power button for 2-3 seconds, then release the Power button while continuing to hold Windows + B for several more seconds.
• If the BIOS recovery screen appears, follow the on-screen instructions.

If the notebook occasionally reaches Windows:

• Connect the AC adapter.
• Install the latest BIOS available for the OMEN Transcend 14-fb0000 from HP Support.
• Restart the notebook after installation.

Take care, and have an amazing day!
