So long story short i installed new mobo, its been working flawlessness. The only wierd thing is that when i press the power button to turn on comp, it turns on for 2 seconds, then turns off for 2 seconds, Then turns on again and works properly. My mobo is gigabyte 990FXa-ud3. I have read in a few forums that some people are having same issue.
Its not my psu, i have a 700 watt.
