So I checked in the device manager but there also I saw only three processors . Then I used a well known tool called CPU-Z , even that shows that i have three processors !. I am quite worried about it . So please give me some help to recover my one processor .</P> Sat, 23 Jan 2010 09:02:03 GMT https://community.intel.com/t5/Mobile-and-Desktop-Processors/One-core-missing-from-my-Core2Quad-Q6600/m-p/269186#M4591 idata 2010-01-23T09:02:03Z https://community.intel.com/t5/Mobile-and-Desktop-Processors/One-core-missing-from-my-Core2Quad-Q6600/m-p/269187#M4592 <P>I'm having the same problem using Win XP.
