Best BIOS settings for my Gigabyte 880G-UD3H Motherboard

Hi. I'm Not Sure which Category should i Put My thread into, but anyways.....
I recently purchased my new gaming computer. Seems Perfect. But as soon as i tried playing Games, The Game freezes during 1st minute of the game. Sometimes I can Play 1 hour without the game locking up. This Happens quite often. I tried updating my graphic drivers, download microsoft updates, Check Hardware issues but to no avail. Most of this game freezes occur only during gaming. Aside from gaming, everything works Fine. So what could cause this problems? I even tried formatting my hardrive, cleaning the registry bla3, but none seems to work .

So I read several Forums on Game Lock up, Turns out that bios settings could have effect it. Now i wanted to change the settings in my bios, but i'm afraid that something could've gone wrong. Here's My Specs! :



PowerColor radeon HD 5970 2GB
Patriot G-Series AMD black Edition 4GB @1333
Amd Phenom II 965 BE @3.4
Techno Power 1000W PSU
Windows XP Pro 32-bit

Thx in Advance
