After checking my BIOS version, it is the latest and up to date according to Abit. Any other ideas as to what could be causing the problem?

Not sure about the latest BIOS, I'll double check. But as far as Power Plan settings go, they're all on high performance so that shouldn't be the cause. Ill try the latest firmware for my MB and come back to you.

Ah yes, completely forgot. Here's the link below: http://www.megaupload.com/?d=SXBML7SL

Hey Andre, First of all thank you very much for this guide, if it wasn't for you then I would be tearing my hair out now. As for the problem, it seems to be ACPI.sys that's causing all the issues. Yet I have no idea what ACPI.sys actually does so I have no idea where to start. I do know however that after a clean boot the problem does seem to go away. Also, the CPU usage symptoms arise only when I launch a game and play it. Afterwards, when the game is closed, the CPU usage still remains very high, I've observed for a while to see if the problem might calm down, but it still persists way after the game's process has ended. Here's a screenshot of my results: http://www.imageupload.org/?di=12129271965916 Very much appreciated Andre, and sorry for the trouble.
