HELP! Problems with Internet connection

It's been like months, my internet connection has this problem:

It is always in good status, but whenever I want to play Counter-Strike Source or open Steam, sometimes it is good to connect right away, but most of the times, whenever I click to join a server, it says that server not responding, and I know it is my problem that I cannot connect to it, but all the other things worked good (IE, MSN Messenger) so i don't what problem is that, if I talk with Verizon (my internet company) I don't think they know the problem they wil just say "We are monitoring your connection and it seems good"

SO please help me if you know about this kind of issue.

Thank you!!

Although I guess the only common denominator is CSS.

How about firewalls? Have you cleared all your temporary Internet files and cookies?

You might try looking at your Event Viewer for any synchronous entries:

Event viewer: rt. click My Computer then click Manage then Event Viewer.
Or: Administrative Tools/Event Viewer or Start/Run/ eventvwr
Open the system as well as the application tabs & look for X errors. Click error line for details.
Post back the source & event id & Description especially of errors that seem to coincide with this issue.
Also check the Information lines that might coincide with this issue.

If you deleted them then that's about all you can do there.
