My computer: Asus P5KPL-AM IN/ROEM/SI, bios version:0508 Processor: Intel(R) Core(TM)2 Duo CPU E7600 Recently I changed processors. I had Intel Pentium 4, and few days ago I changed it to Intel(R) Core(TM)2 Duo CPU E7600. Since then I have problems with turning on computer. So, when I turn on my computer, power button won't turn on the light on it imediately. Only after some time. That time processor fan starts to spin very slowly, then stops, and after few seconds starts to spin normally, only at that time power buttons turns on blue light, I don't understand why it doesn't start to spin normally immediately after I press power button? Why power button doesn't immediately turn on the light after I press it, like it was with Pentium 4?
