Excuse me everyone, first i'm sorry for my bad english, i'm not from US.
I had a problem with my laptop processor on cpuZ it's show that it has only 1 Cores and 2 Threads, when bought it, i'd check it shows 2 Cores and 4 Threads, but the next i checked again than it's shows 1 Cores and 2 threads.
can anyone help
ooh... nevermind.. thank you.. i've fix the problem..
in advanced boot section in msconfig i must unchecked it first.. number of proccessor..
i checked it 2 procesor before.. because i think 2 Core 4 Threads mean 2 number of proccessor. False understanding..
That cause windows only detect 2 proccessor 1 physical cpu + 1 virtual cpu (2 threads)..
So i unchecked it first.. then reboot.. then it back to normal.. it shows 2 Cores and 4 Threads again..
