Windows 8, EQ crashes and causes laptop to restart?

[Liba60]

Hey I recently downloaded eq and started playing a bit.I used to play on Windows 7 and have no problems, downloaded windows 8 after reformatting and now EQ will crash and cause my laptop to restart? I've tried compatibility mode and still no dice. My laptop is an i7 4gb ram, that plays sc2 with no issues so don't think it's hardware? Any ideas of anything else to try? EQ might run for an hour or so before crash and restarts, or it might only last 10 minutes, it differs.
Thanks, really need any ideas?!
