got a bug with boxing

[Firriann]

ok, so my bug is, i log in one of the 2 chars, my bst. then i load in the 2nd, a druid. i have no problems logging in and not much lag either, but sometimes, my computer totally reboots without any error messages of any kind. it just reboots =/ it doesnt do it when i only have one char in, only if i have 2 EQ running (two on one comp). that trouble started about 2 months ago, never had a problem running 2 EQs at once before that. i can run EQ and lineage 2 at the same time, but 2 EQs just dont work =/ anyone had that happen to them or know what might cause it? i desactivate my anti virus when i play EQ so it's not the live update.
