4 Keyboard + mouse connectors problem
I got this PC Compaq Presario 7170, which had a problem with mouse port. It didn't work. Serial mouse is working.
I replaced both ports and soldered a new ones, but since then my keyboard is also reporting a problem on boot - Keyboard error. But it works. If I press any of the keys with led light (num pad, caps lock or scroll lock) keyboard stops responding. I need to unplug it and plug it back in to make it work again.
Even though my soldering is terrible, I checked all the leads and everything is connected. I also checked surrounding caps and resistors and they seams fine. At least, what I know to check.
Any idea where I could go next?

Yes the new photo helps a lot! Sorry, but your solder connections look terrible. You may have a "cold" solder joint by looking at them.
I would neaten up the solder points by just touching it with the soldering iron until it flow and then slowly pull the iron away. Don't overheat and pull the iron away as soon as the solder flows. This could possibly be part of your problem ???
My motto is always look for the simplist solution first. You what is different and what did yo acyually do? You soldered so look there first.
It could be another component but start with the soldered connection.

No need for sorry, I know it is terrible. My soldering wire was too thick, but now I got a better one.
If there is a cold soldering, it wouldn't beep from the conector till the wire on the board (where it is stripped). Soldering point is between those two
