I have updated all the bios and drivers for the pc. Seems that when ever i run a game or any program that has decent graphics for longer then an hour it will Black screen or complete reboot.At first it did it every 5 mins the i changed the ram speed in the bios from 400 to 333. any ideas?

Try a slight increase in the vcore and vdimm voltage. Might stablize things for you.
