Apparently this model is not sold nor supported in North America. Or many other countries except Thailand. That's the only Acer website I could even find it listed on. I suggest you contact the Acer technical support dept. closest to the country of origin and ask for a recovery cd.
It's possibly the 2400 series drivers, ie: 2420, 2430 would work on this model but I don't know since you failed to id each of the hardwares.
