ELI5: if current computer graphics and processing are so much more powerful than the ps3/Xbox360, why can't the games be emulated perfectly on a PC?

Also, why does the ps3 have problems running ps2 games perfectly? This makes no sense to me.

Your standard PC speaks a different language than the consoles. The software (the game) needs to talk to the operating system and the underlying hardware. Imagine having to communicate with someone who speaks a different language, you would need an interpreter (emulator). This would slow down your conversation. This also applies to ps2/ps3 and the Xbox/Xbox 360.
