Hi, i am having i5 3rd gen cpu with gigabyte h61m-s along with msi 1660 ti 6gb graphic card. Psu - cosair vs 550. Ram 8gb ddr3 cosair. On hitting the power button, all fans and graphic card lights are turning on for a min and goes off instantly. I wait for 2-3 mins but still its not working. Need a suggestion where i am wrong.
