Hello new to the forums. After dealing with this issue for over 2 weeks and constant tinkering im freah out of ideas. Every time I launch a game thru steam mainly Half-life 2 games i can get anywhere between 5 to 15 minutes in to it the game will freeze for a second then black screen then back to desktop with a message HL2 has stopped responding. I check event view and thisd is the messages i am getting:

I have tried reinstalling steam, games, direct X, reinstalling windows, reintalling SDK 2007 I have also run Hard ware diagnostics on all my equipment. Can someone please tell me what im missing. pretty please :)

Try updating your drivers to the latest WHQL version. If the problem still persist, use the beta drivers. Also make sure that the steam client and all of the Half-Life games are fully updated and that they are not blocked by Windows Firewall.

well seems to be a stick of bad Memory just did a entire run thru of Nightmare house and no crashes. thanks M1GU31

First see this:-

Problem signature:
Problem Event Name: APPCRASH
Application Name: hl.exe
Application Version: 1.1.1.1
Application Timestamp: 3fd11900
Fault Module Name: serverbrowser.dll_unloaded
Fault Module Version: 0.0.0.0
Fault Module Timestamp: 42f19fab
Exception Code: c0000005
Exception Offset: 0d28e290
OS Version: 6.1.7601.2.1.0.256.1
Locale ID: 1033

Just see the name of "DLL" file which is causing this error(in my case it is serverbrowser.dll). Search this file in your game directory. You may find 1 or more no. of files. Select its properties and then under Security tab click Edit, click Add. Now enter your username and tick Full Control.
Do this for all DLLs which are causing this error. If you are changing game, instead run the game directly instead of changing. E.g hl.exe -cstrike, instead of going through hl and then Counter strike.

Hope this helps...:)
