I've honestly tried everything. I've been building PCs and water cooling them for 15-20 years now. Apart from one damaged socket due to my own stupidity I've never had an issue like this. What perplexes me is that it booted up the first time to give me the code, now it doesn't even power up. I can't remove it from the case as it's all watercooled. AMD should really come up with a better CPU/socket design if it's this bloody fussy. Getting a bit sick of it all now considering what I've spent.
