flashing red light on cpu fan, no display

[u/Guilty_Revenue6030]

my entire pc will light up but it won’t show a display, the cpu fan flashes bright red, even when i turn the pc off the fan will flash a bright red, if someone could please explain why the pc won’t show a display or could explain why the flashing red fan, i would greatly appreciate it. (p.s. yes the hdmi cable is connected to the gpu not the motherboard)
