What is the make and model of your PSU and how old is it? The card can drop into your board but if your PSU is incapable of delivering the necessary power to the entire system, the upgrade is worthless.
I have updated my PSU to 650 watts
still having the same issue.
GA - 78 lmt ubd 3 (rev. 5)
8gb ddr3 Corsair Vengeance
AMD Fx-6300
MASTERBOX MB500 (cooler master)
