Exactly what the title says...when I try to boot up my PC, the fan starts making a tremendous amount of noise (sounds like a 747 to be honest), and I get nothing but a black screen. The light on my monitor remains amber, indicating that it is getting no display whatsoever...
However, when I unplug the CPU fan, it boots up normally (save for a message stating that the fan is not plugged in) and I can plug it in after Windows has started.
Any help is appreciated!
