My Left 4 Dead 2 keeps crashing?

[Micoo]

I've recently installed a ton of mods for L4D2, but when ever I start the game up it makes a whistle noise and then crashes instantly. At first I though that the mods were causing the problem so I uninstalled them and launched the game; the same thing happened.
I really don't know what the problem could be..? Help would be really appreciated.

Try to verify the integrity of files in the properties of the game. This had happend to me twice and after I verified the files the game ran just fine.

Thanks.. I'll try that

It didn't work ^^

I've even uninstalled the game, reinstalled it, and then tried to laumch it, but the same thing keeps happening

Set Launch Options "-autoconfig".
I doubt it's a hardware conflict, but it won't hurt to try.

None of these things work, but I think it might be due to the fact that I've recently downloaded Windows 8.1 because it seems a few people are have a similar problem

I've ran in in compatabillity mode and it seems to work.. I needed to downgrade to windows 7;
For anyone else that has this problem

C:\Program Files (x86)\Steam\steamapps\common\game\

Right click application file then properties then compatibilty.

Yeah the game started crashing for me today after I downloaded Windows 8.1. It loads up the game I joined, but when I "click to play" it instantly crashes. I will try this. ^

I tried running in Windows 7 Compatibility mode but it didn't fix the issue.

whats your problem?

Everytime I join a game, it loads up the game and then I'm spectating the character I'm about to play as (like it normally does) and it says "IDLE: (player name)" and "Click to play as (survivor name)". When I click to join in and control the character the game crashes. It doesn't matter what mode I'm playing, Campaign, Versus, Single Player, they all do the same thing. This started happening after I downloaded Windows 8.1. And the compatibility mode hasn't worked for me either.

I honestly dont think there is a fix for this without reinstalling the game which I consider to be a last resort removing any custom sounds you had which isn't a big deal, but yeah Ive read so many topics about this and not 1 of them had any solutions. Most people had simple outdated drivers that were their fix but ppl like me are still locked out from playing this game

I have the same problem with Win10. Is there a solution?
