Certain video games won't launch


I have a custom built PC that is about 3 months old. Was fine for a month or so until it started giving me errors when starting up games, the only fix was to reinstall my graphics cards drivers. This only happened like once every week or 2. Up until the past few days and now it happens more often.

It's a weird one because after reinstalling my gfx drivers Crysis 2 works fine, but I've tried games such as trackmania nations forever, trackmania 2, mirrors edge and portal 2 - these all fail to start. some give me error mesasges, tohers just close straight away.

Here's one of the errors I'm getting:
Mirrors Edge - Failed to create DXT texture. THe game requires DXT support. If you have manually disabled it, please re-enable and try again.

I was getting an error on trying to launch Trackmania 2, something to do with direct x and shaders (can't remember specifics because I've since uninstalled it).

I've tried disabling on board graphics, re-installing direct x 11 (Seems like it could be a DX fault?) and I've even run a program to make sure every driver on my PC is of the latest version... all to no avail :/

Any help would be grand, anything else that may help assist then just ask. Thanks!

P.S. I have 2 monitors, a standard VGA monitor and a HDTV

More about certain video games launch
  1. It wouldn't let me edit my post so I'm replying... Here is a screenshot Of 2 error messages I got when trying to run a DX11 Benchmark app (Top 1 came first):

  2. Definitely sounds like you need to get a clean reinstall of DX11. The DX11 DL (I don't know because I don't have DX11 cards) comes with all the DX8,9, and 10 stuff, right? Or is it standalone? If so you needa get them all.
  3. Erm.... haha, I'm not sure, but it would make sense if it did. Could do with some info on how to do a completely clean install of DX11 if anyone can offer any advice on that?

  4. i've tried EVERYTHING i can think of apart from re-formatting my hard drive. Can anybody at all help? I've just bought Skyrim and this won't work either :(
