I just delidded my 7700k on my MIXH and changed out the fluid while I was at it. When I turned it on it was only on for 10-15 seconds then shut off and won't respond to the power button. I hooked the psu up to an old motherboard outside of the case and the psu turns on. Three possible issues I can think of. 1. Water got on something but I didn't see any problems. 2. one of the washers holding on cpu block is still wedged inside mb somewhere, I thought they were plastic so I wasn't worried but found one and they are infact metal, there's one or two unaccounted for. 3. cpu cracked or burned up, I went for a naked die and it may have broke or wasn't making good contact with block.
Thought's?
