Freezing While Home Network File Transfer!

[burger1113]

I've tried doing file transfer before, from my win7 desktop to xp laptop, and my desktop would
freeze every time, making me force-reboot. Back then, I just thought it was just a laptop problem,
but I just tried this with my new second desktop with win7, and it still happens!
the old desktop that freezes's specifications are as follows.
Q6600, HD5770, 4G ram, 1TB HDD, Win 7 64bit

I must say I know more about computers than anyone around me, but I really can't figure out
what the cause of this could be! Please help.
