ASUS ROG Strix B450-F Gaming Motherboard Issues

[YawgmothWorker]

Hello, I'm having issues with my motherboard, and here's my incident in detail:

I was using my computer as usual, went out to do some errands, and when I returned, my Windows was completely frozen. I performed a hard reset, but it didn't boot up again. The motherboard's VGA LED was lit in white, and nothing else happened.

After several reboots, I managed to access the BIOS, which had graphical errors (red spots all over the screen). I exited the BIOS, and it indicated that my Windows files were corrupt. Upon attempting to restart, it didn't even boot into Windows.

Things I tried:

• I attempted to reset the CMOS. After doing this, the graphical error disappeared briefly, but it returned when I moved the mouse, and I couldn't boot into Windows again.
• I also tried updating the BIOS, and the same happened: the error disappeared briefly but returned.
• I visually inspected the components but didn't find anything unusual.
• I tried booting from a USB drive with Ventoy, Hiren's Boot CD, and the Windows installer. I reached the Ventoy boot screen without issues, but none of the ISOs would load.

Before this, I had some electrical issues where the power went out, and when it came back on, the PC wouldn't turn on. I had to disconnect and reconnect all components to get it to power up. I measured the power supply voltages without load, and everything seemed fine. Voltage measurements from the BIOS were also within acceptable ranges.

My components:

• ASUS ROG Strix B450-F Gaming Motherboard
• AMD Ryzen 3400G CPU
• HyperX Fury 8GB 2666MHz RAM x2
• MSI Nvidia 1660 Super 6GB Graphics Card
• Sentey SDP650-FX 650W Solid Power 80 Plus Power Supply

I suspect the motherboard is damaged, but I'm not sure. Any recommendations would be greatly appreciated.

Hello, @YawgmothWorker 

Based on the scenario you described, please refer to [Motherboard] Troubleshooting - No Power/No Boot/No Display and test with minimal components to isolate the possible cause.
If possible, please perform cross-testing with the CPU, GPU, PSU, and related hardware.
Also, kindly refer to the link provided below for further issue identification.

Due to your situation involving power outages, it is difficult for us to ascertain whether hardware anomalies were caused by current waveform disturbances.
If you have already attempted the aforementioned troubleshooting steps and are still encountering abnormal displays during startup or an inability to power on, we would recommend sending it in for repair diagnostics.
Please contact ASUS - support center if needed.

Thank you.

Hello, @YawgmothWorker 

May I ask if you have referred to the links I provided and attempted troubleshooting for both software and hardware issues?
This includes checking for any damage or debris on the GPU's golden fingers, cross-testing the GPU in different PCIe slots, or performing the steps mentioned in the provided links, such as testing with minimal components to isolate the possible cause.
If possible, we also recommend cross-testing with another GPU or hardware to eliminate the possibility of individual hardware issues.

Thank you.
