Hi everyone =) . I was just wondering , I have unlocked 2 cores on my ii x2 550 BE CPU , I get to windows turn on CPU-Z , it showes 4 cores - 4 threads , however , sometimes when I'm booting the PC , it doesn't let me go to windows , ( don't get past the logo ) . If I just restart it and try like 3-4 times , I eventually get in , used prime to check stability , 24 hours and no problem . temperatures are around 55 . any idea ?
