[HELP] PC Bricked during adrenaline update

Hey everyone, I'm in a nightmare scenario and need some technical insight.

Specs:

• CPU: Ryzen 7 7800X3D
• GPU: XFX 9070xt Swift
• Mobo: Asus Tuf b650
• PSU: MSI mag a860gl

3 days ago, I upgraded from a 6750XT to a 9070XT. I did a clean DDU wipe and installed the 25.9.1 drivers. I specifically checked the option in DDU to "prevent Windows from downloading drivers."

Everything was perfect for 3 days. Today, while I was using the PC, (i'm guessing Windows decided to ignore my settings) an adrenaline update started in the background. My system completely crashed/froze mid-update.

After 10 minutes of a black screen (no input detected), I had to do a hard shutdown.

The PC is now effectively dead. When I hit the power button:

• The DRAM light on the mobo flashes for seconds.
• The PSU clicks and cuts power immediately.
• It happens even with the GPU removed and with reseated RAM stick

I've also tried a CMOS reset and BIOS flashback but the issue persists. I'm going to a repair shop soon, so i just wanted to know if anyone has had similar issue recently. Thanks
