Just to clarify something when you say secondary power supply above cpu do you mean the 8 pin cpu power connector? That has to be plugged in.
I came across before this issue. did you try with 1 memory slot (such as only slot 4) ?
if there is a possible to try another psu i would be more helpful for diagnostic, I guess.
Hi,so i bought a whole new machine and i'm having a problem with my motherboard (i think). When i finally managed to run the machine, it went into a restart loop. Every 1-2 seconds, it restarts, when it's in dual bios.If i switch the machine to single bios, the machine "runs", but only fans start (keyboard lights do not turn on), so it appears that nothing else works but the fans.
