Parts are all "new" as in i just unwrapped them. I have been collecting smaller bits like the case and lights and fans for a few years. With the price drop i got most of my major parts like cpu, mother board, and gpu. Cpu: 5900x Gpu: xfx 6600xt Mb: gigabyte b550i aorus pro ax, itx Psu: coolermast v850 Case: darkflash dlh21 My bios: f13, but tried f14 and f15 with same results. Ram: corsair vengense pro 8gx2 Corsair led strip Noctua fans to replace case fans for noise Corsair h60 aio cpu cooler Ssd: samsung 980 250g, samsung 970 pro 1t, and Seagate barracuda 4t Ok. Did the bios flash and I get fan spin. However, I cannot get anything else. After flash, the fans kick on. Once they stop completely, I try to boot using power button from case(all plugged in correctly) and no go. Flip off power and clear cmos. Try to boot again. Nothing. Rip out the case connectors and try to short the pins with same result. I know I get power because usb devices light up under 5v. So I have power. Everything I flash, same results. I can get led strips and fans to power up, but nothing else. After 10 minutes, those also turn back off and I have no way to power them up again except to do another bios flash. Running minimal things on the board. Next thing is that it must be a bad cpu, right? Even though it is brand new? Just needing to bounce stuff of someone. Thanks for any insight. I have 5 days left to return the cpu. I fear i may have too....

Chose to replace the motherboard and purchase a replacement. Identical problems mean the CPU is likely dead. It’s frustrating when the new CPU arrives damaged...

You've reconfigured the system by swapping the power supply, motherboard, and CPU. Now you're running a 5600X with identical results. Everything except the fan is intact. You flashed the QFLASH and connected the CPU, M.2 SSD, RAM, and a 6600X GPU. When trying to jump to power, nothing happens. Someone, please suggest possible fixes—I'm using a 16GB USB stick, so I might need a smaller one if available. Need some guidance!
