How I resolved DirectX error under Windows 64 bits

[Voidkissed]

This is still something that needs to be fixed with the game in the long run, this is... ridiculous. >_>; I appreciate you going through all the things you've tried!!
I tried most of these already without success (Only thing I haven't done is a clean install of windows and disabling *all* unneccesary services since I'm not tech savvy enough to be sure I won't botch things, hah).. For curiosities sake, how far did you underclock things? this is the first time I've had to underclock so maybe I didn't do it enough/right. I'm willing to reinstall Afterburner to try, plus I have a Nvidia thing I was going to try possibly as well to underclock.

I downclocked as much as MSI Afterburner allowed me. I believe -200 Mhz on the GPU.

To disable the services, Windows+R, type msconfig, then press Enter. Tick "hide Microsoft services", untick anything else. Enter and reboot.

Thank you for the specifics! I'm going to try both things shortly and report back.
Thanks for making this thread and getting more specific for me!

Edit: I think it worked! In DirectX11 too, though I was and am prepared to try in 9 if the error returns. But so far so good, got 3 hours or more or play time without the issue I think c:
