I was playing some games on my gaming PC yesterday when my cat stepped on the power switch to the surge protector, causing it to shut down and then restart in about 0.25 seconds. From that point on, the PC has been unable to boot beyond the ASUS splash screen.

In the BIOS I can enter, it identifies the memory and CPU, but the motherboard lacks graphics support. The Radeon 6900XT appears to be functioning properly in BIOS and is attempting to start.

When trying to boot, I receive a post-message prompt where I can enter BIOS, followed by just the ASUS logo with a spinning window that keeps looping indefinitely. It doesn’t freeze or return; it continues spinning for over 45 minutes before I eventually give up and restart.

Trying to access the automatic recovery option also fails—it displays a message saying automatic recovery is starting, but the wheel spins unchanged.

I’m unable to boot using recovery media or an OEM Windows 11 installer USB drive.

This morning I replaced the motherboard, thinking it was the issue, but the new one behaves identically. Both SSDs were swapped with identical bootable drives without any modifications. I’ve tested each RAM stick separately and then purchased two new ones, yet nothing has changed.

Currently, the only components that remain unchanged are the CPU and the Radeon 6900XT.

I tried using an older EVGA Supernova 750 power supply, but it didn’t help.

It seems the CPU might be faulty, but I’m not sure if this would even allow the system to run without it. That’s probably the next step.

System specifications:
Asus ROG Crosshair Hero VII motherboard (replaced today with a Asus B550-Plus, no changes)
Ryzen 9 5900X with Noctua air cooler
64GB G. Skill RAM (replaced with 16GB Corsair RAM, no changes)
EVGA Radeon 6900XT video card
EVGA Supernova 850 Gold Plus power supply (replaced with an old EVGA Supernova 750, no changes)
Evo 980 SSDWDD Black SSD (both SSDs were removed and replaced with a 970 Evo, Windows 10 install, no changes)
Windows 11

if you have a local computer shop they will generally provide system diagnosis
that involves checking each part separately to identify the issue.
or if someone in your vicinity who knows their setup
uses their machine to test your own components.
if you manage to resolve this quickly and pinpoint the problem
you might still be able to cancel any extra purchases made during troubleshooting.

if you continue using this surge protector you might consider testing it without it and with a different wall socket.

Thanks, I found a few local suggestions. I'm also heading to some areas with Micro Centers next month, and if I haven't fixed it by then I can still try them out. I value being able to handle problems without needing to visit a store, so having alternatives is helpful.
I'm less concerned about having extra equipment—when my main PC is ready, I can easily create a solid backup system from the components I already have. The AM4 and DDR4 specs aren't the latest, but the 5900X meets all my requirements with some extra space for future upgrades.

I might use your backup computer to download a new Windows 11 ISO with the media creation tool and install it on a USB drive you’re certain is reliable, using Rufus.ie. Then I’d remove all the SSDs and other drives before attempting to boot from the new USB. Or I could try booting from another USB running a Linux distribution (which I suggest keeping handy for any situation) to observe how it responds.

Power interruptions usually aren’t caused by drops in power, but by surges when electricity restarts. If this happens again, I’d first check the power supply’s circuit breaker.

Tried the media creation tool and a standard USB drive without an SSD, along with the original Windows 11 USB.
