The power light (blue) is off and H.D.D (red) light is blinking in my CPU. The computer is functioning normally, but why isn't the power light on in the i-ball cabinet? -
Power button LED is blinking while I use the PC after I upgraded my motherboard, CPU, and RAM. But the PC seems to be working fine. It doesn't happen all the time,
