    CPU @ 100% in Task Manager.. but in error


    Sailindawg, did Resource Monitor show some silly high % use, in the millions/billions? Does the 'Details' tab in Task Manager show 'System Idle Process' normal? It does sound like you have the same issue, I've still not fixed it. You might be lucky and a BIOS update works for you as it has others, I'm stuck on the B2 stepping which means I can't upgrade the BIOS *Sad

    MrPumpkin, what process does task manager say is using the most CPU usage?

    CPU constantly at 100% in task manager

    Hi, on the users tab of the task manager the CPU section always displays 100% CPU usage, but when viewed with Core Temp the usage percentage is at it's correct % which is 0-1%. Is there anyway to fix this? Thanks.
