Hi z300m thanks for your time to help me with my issue with blinking light. Yes you are right and I also checked online manual and google search it came up with that. The leds2 and le5 is blinking, and sorry in advance for my poor English. I was bit paranoid because I just build the system last night and just powered it up today for the first time. And these blinking light I thought I done something wrong. I still have to go over the hurdle of setting it up god help me you guys makes it look so easy. But it is vey hard to setup if you don't know what you doing.once again many thanks for your help
