Hey everyone! I have a quick question regarding a really weird problem I'm having with Half Life 2. Whenever I start it up, the Valve splash screen plays out all right, but then the game crashes to desktop with a "HL2 is not responding" error message, here are the details: Code: Problem signature: Problem Event Name: APPCRASH Application Name: hl2.exe Application Version: 0.0.0.0 Application Timestamp: 4445c334 [B] Fault Module Name: StackHash_abcc[/B] <------ [I][U](This seems important..?)[/U][/I] Fault Module Version: 0.0.0.0 Fault Module Timestamp: 00000000 Exception Code: c0000005 Exception Offset: 74ece2d4 OS Version: 6.1.7601.2.1.0.256.1 Locale ID: 1033 Additional Information 1: abcc Additional Information 2: abcc8f7853b48d9807d6d51eb1fa5df9 Additional Information 3: abcc Additional Information 4: abcc8f7853b48d9807d6d51eb1fa5df9 The reason this error is so baffling to me is that the game ran fine less than a day ago. Nothing has been changed except for my location, which shouldn't matter as far as I know. One fix I've thought about using was to simply run the game in windowed mode, however I can't seem to do so. Does anyone know how to make this happen? I've tried adding the -W argument on the shortcut that launches HL2, but it still runs in fullscreen...? Anyways, any help is greatly appreciated! Thanks! EDIT : My computer is a Alienware M17 laptop, the specs far exceed the minimum reqs. for HL2, I'm running Windows 7 Ultimate. Drivers, DirectX, etc are all updated.
