Laptop wont boot after changing fan

HP Recommended
Microsoft Windows 10 (64-bit)

Hi, the bearing was going out in the fan, so I ordered a new one and swapped it out. Now the laptop wont boot. The power button works, and lights up after I press it and the new fan starts turning, but nothing shows on the screen. The led on the caps-lock button blinks 3 long and 2 short. I researched this and seems to be a boot failure, related to BIOS. I tried everything I found, including

  • re-seating the ram. I tried isolating it to one ram stick at a time, swapped them around, etc.
  • I tried connecting external monitor, and nothing shows on it.
  • I tried a hard reboot, and even unscrewed the battery and removed it and held the power button down for 30 seconds to be sure the capacitors were drained.
  • I tried removing the hard drive
  • I tried the BIOS recovery sequence. Which was holding down windows key + B, pressing power button for a few seconds, letting go of power and continuing to hold Windows + B. I tried it several times. Also tried doing the same but with holding down Windows + V
  • I tried putting the old fan back in (even though new one sounds just fine)

Nothing has worked. I'm starting to think I shorted something out and ruined the motherboard. I was really careful not to touch it, but maybe my sleeve brushed it or something? Any ideas of what the problem could be?
