My bad luck has struck really hard for my PC upgrade. I bought Ryzen 5800x CPU + ROG Dark Hero mobo to upgrade my aging 5820K i7. That Ryzen is insane cpu compared to my old i7. Everything runs at higher framerate and that Ryzen runs a lot cooler than my old i7 with a lot more performance and finally my GPU is the bottleneck of my frankenstein of a pc xD
So my bad luck started with a leak on my bigger 2x140mm water radiator, so I had to downgrade to a single 2x120mm rad. My original plan was to have 2x120 after cpu and 2x140 after GPU, but my chassis is too small for fit them both at the same time, so that leak doesn't really even matter. (And the system runs cool enough under heavy load with that 2x120 rad anyways.)
So I was enjoying better performance from mid august until early october until one saturday morning my pc wouldn't boot. Didn't even go over POST. So I check what Q-codes I can see from the mobo and I got that dreaded 0d code that no one knows meaning of (Reserved to future AMI Sec codes). So I got a replacement from RMA and the one I got was physically broken. RGB headers were bent inwards and start button was mostly ripped off from the soldering. So I had to RMA that one too.
I guess their RMA is handled by a bunch of ents, because it took like two weeks before they decided that I should send that mobo back for closer inspection. So I got an email last week about that they'll send me a new one and I'm still waiting my third ROG mobo to arrive.
So yea, I'm pretty sure that my rolls for luck were pretty low with this upgrade
