sorry for long read I picked up the board from here on the forums w/ a 2700X. Using with my existing 2x8G GSkill 3600 @ 3400 for stability... ( relevant to VRM temps perhaps ) evo supremacy and galax 1080Ti HOF with block. idle temps reprorted as 33-40 on cpu and 20-21 on gpu ( 2x280 rads ). I then plumbed a new WC loop into it and aside from what I believe to be normal 2700X temp concerns, it was running fine for this last week. idle temps reprorted as 33-40 on cpu and 20-21 on gpu ( 2x280 rads ). Fine until yesterday / day before , when I picked up RotTR game and started playing it. Suddenly, a psu power off happened while playing RotTR. I immediately unplugged everything and began looking for a leak.. nothing.. Ran the loop for another hour or two ( no power to the board ) using a jump started psu.. seemed fine.. So plugged all back in and booted up. Everything seemed normal, smashed a few hours of BF1 and skyrim, then went back to RotTR. Another poweroff.. :/ Thought it was temps this time, so I opened the case and threw a few more fans in there inc a 40cm desk fan on full ( just pointed at the board / VRMs ) hwinfo showed under game load showed vrms ~ 50 mobo 38 cpu 40 gpu 40 etc ( so nothing to worry about ) The poweroffs happened a few more times as I was attempting to troubleshoot ( always when playing RotTR) Eventvwr had nothing to say other than restarted rom a power off... Then yesterday, the board just doesn't post ( this happened after the latest hard power off ) When psu is turned on - board will light up w/ all leds etc. When powered on via switch, all fans start spinning, WC pump is engaged, but nothing happens... no debug leds. Ive reset cmos and replaced battery, swapped out ram.. only-thing left is to breadboard by draining and stripping the loop, before Im left with RMAing something ? any thoughts? thanks!
