I received a new board (RMA'd) late Jan 2013. Installed it & all was OK. Until now.
Came to turn it on & it cycles on then off repeatedly. I reseated everything including the CPU, more paste (all done only 2 months ago) and now it doesn't cycle, just stays with the fans roaring away until I kill the power. I've just tried a 750w Thermaltake PSU - still the same. No beeps, no POST codes on the led display, and the monitors spring to life with their Dell message then drop back to no signal.
Before it was RMA'd in Jan it was working, and all the componemnts were getting along fine. 2nd gen i5, 8gb suitable RAM (can't remember specs but OK'd by the last Intel RMA chap I spoke to), HD6770 graphics card, Xclio/Meridian 530W PSU
I was hoping that the no codes on the POST display was a clue, but haven't been able to find anything.
Please can anyone help, as this board has spent nearly as much time at Intel as I've had it going
