Hello guys,

My CPU usage (I7 920) in task manager has been really high for the past 3 months and i've finally realized yesterday that it was because only ONE core was detected. I've tried all the fixes possible such as unchecking the box under msconfig, trying to get the Bios to fix it... Everything i've tried so far did not fix it. Task Manager only shows one core, CPU-Z only shows one core and one thread, etc.

I would be really grateful if anyone knew how to fix this, because it's driving me crazy.
