When I try to turn on my pc, it wont display anything on my monitor. All fans are on, but I see a red light (cpu) coming from the MoBo. My friend and I checked to see if maybe the cpu had bent pins; it was fine. So we had redone the thermal paste and screwed on my fan, turned on the pc and same thing happens. All fans turn on, no display, and red light on cpu. Any help on this would be appreciated.
