So I get a txt today from the fiancee' saying the computer was making a clicking noise, so she turned it off. She said she had the log in screen up but when she tried to log on it wouldnt let her (I think the screen was froze where it was at). So she turned it straight off (which she said she had to push the button a while before it turned off). I took off the side and don't notice anything out of the ordinary. I unplugged and plugged in and it still doesn't work. Swapped out video card because I thought that may be the issues but still not bootup. Switched hard drives with an old one I had laying around to still nothing. There is a green light behind the tower by the power plug that is green and on and there is a yellow light inside the computer by the motherboard that is on when plugged in. Nothing will turn on nor will the fans even spin to do the 'pre-startup' it usually does? Is this the motherboard? Is it completely fucked now? Thanks for any help and information!
