Windows 8

Direct X 9 - No problem.

Any games I try to run with DirectX 11 though fail to launch.

Oddly enough it only started this evening, I rebooted for something completely unrelated and following reboot the games wouldn't load.

Eventlog shows nothing changing between times, nothing installing or updating etc.

So far I've:

1. Removed/reinstalled the graphics driver to a newer version.
2. dism /online /cleanup-image /restorehealth which repaired an issue which sfc /scannow couldn't.
3. re-run sfc /scannow to which it states there are no issues.
4. Steam games I've verified the local cache, no issues.

Several reboots in between times.

Any ideas?

As I haven't hopped up to 8.1 I'm tempted to do it, although I do tend to favour clean installs!

Solved:

Downloaded a DX11 tech demo from Nvidia which worked fine, so concluded it was Steam. Had a bit of a dig and found that it had updated earlier tonight, probably shortly after I restarted the PC.

Taken myself out of the beta steam client program, let it roll back to the normal version and it's launching games fine.

I've been in the beta client program since it started, first time I've had a problem but at least it's fixed.
