I recently built a new system and I noticed today after trying out a game (Minecraft), my system power supply started to make these weird "sparking" sounds. Sort of like a coarse sand grain hitting the fan and when I turned off the computer to check it out, I felt the power supply and it was really warm. Almost hot.
Is this something I should be worried about? Please help, thanks.
Before sending it to the shop, make sure that all things are plugged in right. I remember this happening to one of my older computers, and the only reason it was making that noise is because it was unplugged ever so slightly, and the noise was the sound of the electricity "jumping" about 1cm to reach the metal prong of the socket.
