So i built my computer 4 years ago, and has worked well until 2 days ago. I was playing games and watching movies like i normaly do then turned of my pc. I woke up the next day to turn it on, the lights turned on and the fans were working. But i got no signal to the moniters and my led keyboard wont light up. So i tried moving the gpu to another pci slot and it didnt work. And thought it was the psu so i went out and bought a new one and it still didnt work. So this a mobo problem or cpu? I tried switching the ram around and that didnt work either?
