I just upgraded the CPU in my computer from a Core 2 to a Core 2 Quad. The computer runs great and cool, but I’m having an odd problem upon boots. If I reboot the computer, the OS shuts down and goes to a blank screen, but the power does not turn off or reboot. I have to hold the power button to turn the computer back off and back on.
Also, when I start up the computer cold, the fans will run full blast and the unit will not post. Then, I will power down the unit and start it up again and everything works fine. These things happen without fail, and once started the system is working fine. Anyone have any ideas? It is more annoying than anything else right now. It all started after I upgraded the CPU.
