ACPI.sys+0x1af7c Consuming CPU


  • Hi

    I have had this problem since the machine was purchased. Upon booting the machine all is fine, however after a few hours CPU spikes up to 15% and stays there unless I reboot. Virus check comes back clean as does spyware. Completed Dell BIOS diagnostics, no problems detected. Booting in safe made makes no difference.

    My machine spec is
