- Disable your sound. If it works, you will need to update/reinstall/get a different version of your sound card.
- Disable your antivirus. If it works, you will need to add a read-scan exception to the files in the HoN folder. Also, some AV might still interfere in the background when disabled (like comodo). You will have to add an exception/uninstall to test it.
- Check that your windows/graphic cards are up to date.
- Check if your HD light remains solid during the freeze. If yes, find the below file and change it to read-only. Note that this is a temp fix.
c:/users/<USER>/my documents/heroes of newerth/game/reconnect.cfg
