So here's the story: A cat pee'd into my keyboard, so the computer sometimes thinks that I'm pressing the Shift, Alt, or Ctrl keys when I'm not. That's why I bought a new PS2 keyboard, only to find out that the new keyboard acts the same way like the old busted keyboard. Which led me to think that the pee somehow also destroyed the PS2 Port. Question: Can I just desolder the PS2 wire from the keyboard and directly solder a USB wire (replacing the PS2 wire) so that I can connect the keyboard into a USB port on the PC? EDIT: I already bought a PS2 to USB adapter. Problem is it doesn't work like the 'ordinary' keyboards. It's OK for ordinary use but for FPS games, it's not OK. It has a problem with multiple keys being pressed at the same time. (Eg. Pressing 'a' + 's' then letting go of 's' but still pressing 'a' should have an output of "...aaasaaa..." but using this adapter it outputs "...aaas" ). I hope people could understand what I'm trying to say here.
