So, I've looked on Bliz and Allah for a problem like this and haven't found anything yet. Since the patch I've been able to log onto 2 characters fine, but my 3rd character is giving me problems.
All 3 toons have the same addons etc., whenever I try to log onto this 3rd toon my computer restarts. I deleted my WTF, Cache and WDB folders; moved all my addons from interface (except blizz defaults) to a folder on my desktop and I'm still having this problem.
Any ideas?
