From this thread
So after I replaced some RAM memory REINSTALLED damn XP, put the minimum
of programs on my machine and opened the half open connection limit that every windows has.
Normal limit is 10 TCP/IP connection, I upped mine to 50 connections
Cuz I read an article which stated that power users that use a big amount of
connections need more the 10 and that could lead to problems if your connections are to the maximum or trying to exceed it
So far no more problems.
