heres a copy of what i pm,ed you
ok ive had a look and that spec alienware (i saw your forum post) has a 680i sli motherboard (as far as i can tell) and the chipset drivers which should include the network controller drivers are here (these are for 64 bit as per your original forum post)
nForce Driver
now im going on info from here

so make sure your friend checks these specs against his , i looked on the alienware site but their support is seriously lacking , something i find surprising for a company that sells such overpriced pc's
remember to update your post with this info incase anyone else happens across it it will help them too
