Solved DirectX hardware aceleration failed

[PavelChehoff]

Hello,
have recently reinstalled windows 7 x64 and i guess that my directx got some problems.
unable to start any game now. every time trying to lunch game, program gives different errors.
now trying to start world of tanks and it saying:
"Application has failed to start because DirectX hardware acceleration is not available or is turned off".
Has reinstalled DirectX and no difference at all.
What should i do? any ideas?

Windows 7 x64
AMD a8-5600K
AsRock FM2A75 Pro4
4 GB Ram

If you've googled this, you find a ton of people with the same issue, but rarely do they find a fix. the only consistant fix I see if a full reinstall. That said, I'd start with the System File Checker

See if it doesn't find and fix any issues.

Good to hear, glad you got it sorted. Thanks for sharing the fix for you. We often suggest updating drivers, so it's become stale, lol. A Guy
