Hiya,
Built a new PC but it won't POST or anything. As soon as I turn it on, the yellow/orange DRAM light appears and... nothing else. All appears to be running fine, but no display etc.
Motherboard is an ASUS B450-F, with a Ryzen 3600X CPU and RTX 2060 Super GPU. 2x8GB sticks of Corsair Vengeance RAM (CMK16GX4M2B3200C16).
The motherboard box says 3000 series ready but obviously doesn't work. I did use a Ryzen 3 1200 to check the BIOS - using that CPU allows the PC to get into the BIOS, and it shows v3003 as the BIOS version. I updated to 3103 anyway, and tried the 3600X again - no luck.
Not sure what else to do? Have I got a dead CPU? I know it's not a RAM issue as I tried working RAM from another PC and no luck, and it booted fine with the 1200 CPU.
I've also tried clearing the CMOS to no avail. My CPU cooler is a Hyper 212 EVO and I've tried loosening that just in case (and it was also refitted ofc when I swapped the CPU to a 1200 and back again). I don't have a motherboard speaker so not sure if there are any beep codes.
