Windows 7 Problem - Certain programs crash as soon as i start them? :(

[Superfly]

This problem started about a month ago with Windows Live Messenger. Since then i had no problems until last week when my game recording program WeGame began to crash when i start it up. Now today one of my favourite games Counter Strike : Source has started having the same problem.

When starting Windows Live Messenger i am given the Windows Live Messenger has stopped working.. then it closes.
When starting WeGame it usually crashes when i log in, with the same error.
When i start Counter Strike : Source it says Hl2.exe has stopped working and needs to close.

Please someone help me because this is stopping me from using some of the most important programs i use.

I have tried running as an administrator, in compatablility mode, restarting computer, reinstalling all 3 programs, using CCleaner and Windows Cleaner, closing other applications, disabling antivirus, scanning for viruses and many other things.

Any suggestions? Thanks, Ryan.

System Restore....go back to a point before the problem started. You should also download Seatools for Windows and test your hard drive.

Hello Ryan, Could you have a look at this Microsoft Hotfix...:

Symptoms:
A computer that is running Windows Server 2008 R2 or Windows 7 stops responding randomly. Applications or services that are running on the computer stop working correctly. Additionally, you cannot log on to the computer by using the remote desktop connection utility.

Causes:
This issue occurs because of a deadlock condition between the Lsass.exe process, the Redirected Drive Buffering Subsystem (Rdbss.sys) driver, and the Winsock kernel.
