Question

PC won't boot

Shawn Youngs 0

Hello, I have a HP OMEN30L GT13-0014 with Windows 11 Home, HP Moira3 motherboard, Ryzen 5 3600, 32GB RAM, Nvidia RTX 3060, 256gb NVME, 1TB SSD. I did a Windows defender offline virus scan and during the scan the computer suddenly shut down. I waited about an hour and tried to turn it back on, the fans and lights turned on but not my keyboard or mouse and my monitor screen stayed black. I've tried using an alternative mouse and keyboard, trying the keyboard and mouse in different USB slots, trying different Display ports and HDMI ports on two different monitors, I tried power cycling the pc, unmounted/remounted the RAM and GPU, resetting the CMOS by moving the jumper cap from pins 1 and 2 over to pins 2 and 3 for 10-15 seconds. Moved the jumper cap back to its original pins 1 and 2 position and turned the pc back on, removed the CR2032 MB battery for 15 minutes and reinserted it. After all that my screen remains black and doesn't seem to recognize my keyboard or mouse. I'm at a complete loss and could really use some help.

Hi,

In this case, it could be the processor or motherboard. Have you tested different memory modules in different slots, one at a time?

Check if the motherboard has speakers. Turn it on without the memory modules and see if there's any sound.

Thanks

I tried switching the memory modules in different slots too. I did just try booting without any memory modules inserted and my motherboard made 3 long beeps followed by 2 short ones

Hi,

If it's beeping and recognizing the problem, then you'll do the following: take one of the memory modules (if you have experience, clean it with an eraser) and test one memory stick in each slot (Slot 1_A) and try to turn it on to see if it displays. This must be done with the GPU connected; if your processor doesn't have video, then it will turn on.

If it doesn't turn on, remove the memory stick and test it with another one in the same slot to see if it turns on. If it doesn't turn on, test one at a time in the other slots.

Remember, if you don't have experience, I recommend you don't do this and seek HP technical assistance.

Thanks

Hi,

You're welcome. Could you let me know how it went?

Thanks

Answer 2

Based on the provided information, the issue is a no‑boot / black screen condition that occurs before Windows loads (no display, no keyboard or mouse power), after a Windows Defender Offline scan. The available context only covers:

Basic mouse/keyboard troubleshooting once Windows is running.
Windows blue screen / stop code troubleshooting when Windows at least starts to boot.
Recovery options and Safe Mode / WinRE scenarios where the firmware and display are working.

All referenced procedures (Safe Mode, Startup Repair, System Restore, clean boot, recovery options, stop‑code analysis, Secure Boot changes, etc.) require that the system can at least show firmware/boot screens or reach Windows/WinRE. The context does not provide guidance for a situation where:

The system powers on (fans/lights) but never shows any video output.
USB keyboard and mouse never power up.
Firmware/BIOS setup cannot be reached.

Because the context does not include steps for diagnosing this pre‑boot, no‑video, no‑USB‑power condition, there is no supported, documented procedure in the supplied material that can be applied to this specific scenario.
