My messenger gets disconnected very very frequently. Anybody who knows how to solve this problem?

I've seen that others have this kind of problems also. I've a brand new Dell pc with lot's of memory and fast internet. I'm sure it's not an internet connection or not enough memory problem, rather ym connecting problem. I sent an error report but no reply came. I've been using ym since 7 years now, but it's never been so bad. I can't talk, can't send files because I get disconnected every 2 mins. Mainly if I chat but also it gets disconnected when I don't do anything on ym. It's extremely annoying. I'm sure this is a yahoo problem, because when you send an error report via ym you can also see "Messenger gets disconnected on it's own". So I'm sure yahoo knows this problem. I just don't know whether they are working on solving this problem. I tried all 3 connections: no proxies, firewall connection, no network detection. All connections have the same problem: I keep disconnected. If somebody has or had such a problem and he/she was able to solve it, please let me know how. Thanks!
