large .wav file crashes PC

Hi,
I’ve been trying to import large wav file(90mb) into sequencer and each time my PC Just jams up.Mouse cursor freezes up and all i can do is just switch off computer manually.its a real pain!
I’m using have a pentium 3 866mhz PC with 256mg RAM.Before anyone asks,I can’t import the file in smaller chunks as it is a long pice of continuous music:(
Wish blender could import mp3 or ogg files. Anyone know a way around this problem?

thanks in advance
