I have MB MSI Z77A GD65 with Intel 2500K. It worked fine, but I was on vacation for one week and after my return, it dont want to boot. (During vacation, I turned off my PSU and unplugged electric cable from wall.)
After I push power on button, monitor signs no signal and MB stuck with code "d7". After it, I need to push power button for 5sec and it shut off. It will eventually boot up on third - fifth attemp everytime. I tried to unplug everything from board, leaved only PSU, CPU and one ram module, but still same result, it will boot 1 time from 5 attempts (average). Is it clearly for RMA or what should I try?
Thank You for any suggestions.
