Hi agrafuese, i dont overclock my system so bios is set to defaults, cooling shouldnt be a problem in the antec case i have there are two big 3 speed exhaust fans right next to the cpu. i cant check cpu temp as i havent found a proggie for it, but if i open system and touch the heatsink when running its cold to touch (i know its stupid sticking your fingers in live hardware, so i dont recommend anybody doing this). my record uptime has been 8.5 hours (not good for me).

i am at a loss , will keep researching and testing and let you know how i get on

Firewalk

P.S upon checking i dont have forcedepth.kext installed in extension folder,(isnt forcedepth for nvidia based gfx and network) if so my gfx are ati and network is gigabit.
