question to all the computer guru's out there! I just built a computer a few weeks ago. Everything was running beautifully, and then one day I get home... NOTHING! I push the power button, and the PSU fan turns on, CPU fan turns on, Case fans turn on, and there's the light for my ethernet card is on... but nothing else. Nothing shows up on my monitor, no beeps, no power lights, etc. etc. etc.... what happened? Why did it stop working all of a sudden? Can anyone help?
