Not sure if faulty motherboard or PSU

So recently, my computer is not displaying anything on the monitor which made me think that it was a Video Card problem since it happened to me before and I immediately replaced the video card and it worked. This time it happened again and I decided to RMA it since it still has warranty. When I finally received the video card. The results were fine, they even did a burnout test and said that it is good and does not have problems. They returned it after I got home I tested it and it still does not work for me.

And here's what happened:

Before I RMA'd my card, the whole system is running. Fans, leds, hard drives, mouse led, keyboard led and etc. But after the I received the card from RMA and inserted it. The mouse and keyboard led is not turning on anymore but the fans and drives are still working. So it got me thinking that I either have a faulty motherboard or psu. Help anyone?

  1. Without swapping parts it is hard to tell but the lights not coming on points to the board.
  2. Wouldn't the lack of LEDs indicate a PSU issue? Not trying to contradict or confuse but I am just curious.

    Really? I'll try more experiments later, I can't really borrow any spare motherboards to try.

    Maybe spare PSU?
  5. I really don't have a spare PSU and I don't know someone with a spare PSU. My last option is to buy a new one which I don't really want to rush since it may be the motherboard.
