Rákeresve, többeknek volt már ilyen problémája, és Windows beállítás oldotta meg:
"msconfig --> boot tab --> advanced options tab
"Number of processors" was checked and drop down tab said 2. 4 was not an option, so i just unchecked it, hoping the computer would figure it out for itself. and taadaa! it did. everything is showing all 4 cores now!"
Nézd meg, hátha...
