Hey, I need to assemble a PC for my girlfriend. I ran into this issue: I bought an AMD Ryzen 5 3600 GTX 1660 Super MSI B450M Pro-M2 Max 400 Watt. I want it to be quiet but powerful! Also, I have a used GPU and mainboard from eBay. The CPU and RAM I had at home are fine. After setting everything up and turning it on, the GPU and CPU fans start spinning for about two seconds before staying normal. The CPU debug LED on the mainboard lights up for roughly three seconds and then turns off. No other debug lights come on. My monitor doesn’t show anything. What I’ve tried: checked the HDMI cable connection, switched to DVI and DP, tested for short circuits, looked for damaged boards, reconnected everything, even swapped the mainboard to another model that works. I’m pretty sure the mainboard is faulty. Maybe there’s something else I missed before buying a new one. Thanks. Yannik

It seems the problem isn't related to the BIOS because the CPU requirements for that board are met with the 7B84vA0 BIOS, which is the initial BIOS for the board. This suggests a failure in the board itself or damage during shipping.
