Question

As of last week (August 24th 2015) some games won't launch

Aug 31, 2015 6:38AM PDT

So quick rundown: I go to play some Chivalry: Medieval Warfare which was working fine the other day. It prepares to launch through Steam, then pops up with "CMW.exe has stopped working". The game crashed. Same thing has happened respectively to Metal Gear: Ground Zeroes and Titanfall but some of my other games like Awesomenauts and Dota 2 run perfectly. Haven't downloaded anything at all other than driver or windows updates.

I did what I normally do and verified files, updated windows and drivers, uninstalled reinstalled, ran my Anti-virus software, No dice. All of these games have worked despite having a dated OS, but below are my current specs and driver. Hopefully you guys can offer some help.

Specs:
Operating System: Windows Vista Business
Processor: AMD FX(tm)-4300 Quad-Core
Memory: 8172MB RAM
DirectX Version: DirectX 11
Driver: NVIDIA GeForce GTX 770

For each failure I find myself googling it.

When google led to here.

I've checked to make sure they weren't individual errors. It's too convenient for them to all stop working at around the same time. I'm not subscribed to any workshop items, and I've tried the individual fixes for Ground Zeroes and Titanfall to no avail. Thank you though for the quick response Happy

To figure it out we need more clues.

So far we only have what you noted. It's not that I don't have suspects but it's too many to list here.

Look in the Event Viewer for more clues as well as a few errror messages to share here.

Just last week a mass failure like that was traced to 2 areas.

1. The owner had an over reaching security suite. Uninstalled the AV Suite and everything worked. Owner wanted me to fix the AV Suite. Sorry, not my code, can't fix that.
2. Another one found infections. Hours late with scans removal and a lot of google the machine was clean and most games came back the others needed to be reinstalled.
Lesson? Windows is fragile, torrents can be nasty.
