i got this rebooting after my temperature monitor software sent a false 256degC shutdown alarm last night:
ok.
so i following past procedures, as listed in Sigma Omega's Technical help forum thread, with different combos, and sequences (reinstalling steam and Hawken, too. what an ordeal)
nothing but the same damnation as above.
here's what just fixed it, as i never noticed the big green AMD Software compatibility "eyeball":
i downloaded and reistalled DirectX 9.0c
3 minutes. omfg. after all this.
problem solved.
so before you go throwing the amd out the window if you are unfortunate enough to be on limited funds, try the D9 thingy.
good luck, have fun, good night.
YMMV
