OK just to confirm - is this your motherboard:
Overall the system looks reasonable and should be plenty powerful enough to play the game without trouble.
I'm still waiting on the voltages and temperatures as reported by the BIOS, not just what the registry reports BIOS information as. One thing that concerns me is the GT220 is not a very powerful graphics card at all and yet it seems to be running so hot...
Also make and model of PSU please? And what sort of case, and how many case fans are running please?
Yes to confirm, the motherboard is the right one.
What is PSU?
Also it is a regular sized case with 2 fans - one for the chip and one on the back.
I will try to get BIOS information for you.
