| | acpi.sys cpu utilization I have a 3GHz dual core with 8GB of ram on Vista 64 bit and the "system" process, that normally should only be a couple of percent, is always around 47%, regardless of what I do to the system (one of the cores is always at 95-100%). Using process explorer it's showing that it is the acpi.sys process and I'm unable to do anything to that thread. The actual start address within process explorer is "acpi.sys!DeRegisterOpRegionHandler+0x48cc". I have tried to disable all power aspects of the pc from within the bios (full disable and change from ACPI capable to standard mode), this causes Vista too not boot...trying to change the PC type from within vista to a standard pc is not accepted by the OS. Any thoughts? I'm dreading a re-install from scratch. |
