HP 1045 DX Motherboard replacements

Hi, first post here so sorry if Im on the wrong subforum. The thing is that I spilt water in my laptop and appareantly the Hard Drive died along the Motherboard (processor and the rest of the components runs fine as the computer still can be turned on, but I can't install an OS and the hard-drive shows lot of errors during check-up). I can't get a replacement for the Motherboard here because now Im living in Chile and I got the Laptop in the States so the hardware isn't compatible and I've never shoped for a motherboard before so Im completely lost.
This laptop had an Intel one with an integrated Intel HD 4000 Video card, I want to, if posible, get the same one as I was pretty comfortable with it (although if you have another recomendation for under $250 that would be fine)

Thanks for reading.
