now even cant start up. reset bios. cant.

last time same problem but i manage to start up after whole day testing.. buthen prime @ stock no problem. so i oced it to my previous setting. but after few days after restarting pc due to windows update then cannot start up again. No post screen. continous on/off PSU.

i just brought the mobo to service center for RMA today the technician tested it and said mobo's fault. luckily not my proc .. have to wait for one month..
