I have a PC with an BIOSTAR T- Series TA880GB+ with AMD Phenom II X4 B95 and a PSU of 400W (thinking of upgrading it to 500w and a better 12v rail. ) I booted the PC and the LED_1 at the bottom right blinks. So I followed the tutorial at Tom's hardware and removed everything and tested it by keeping each part in at one time. Then, after putting everything in, the LED_1 Just remains on. But LED_2 is off. Please help me with this.
