    System Process eating up half my CPU


    For the past few weeks, my system process has been eating up my CPU, using nearly 50%. I'm not quite sure what do do about this. Are screenshot showing all my running processes.

    The most likely cause without digging into it further is that there is a bad driver sucking up 100% of however many CPUs it's using.

    You can try to get some more details out of the task manager (such as the actual DLL name that is using the CPU) or try downloading Process Explorer (Process Explorer) and see if that will tell you. If you can get the name of the actual driver file causing the problem, then you can try uninstalling that piece of hardware and installing a different driver for it.

    Edit: If you download Process Explorer, run it, double click on the "system" process. Then select the "Threads" tab (Click ok on any error dlg that comes up).

    You will see a list of running threads in "system" and the CPU usage of each. Each thread also lists the file XXX.dll or XXX.sys etc that the thread is executing for. That file name can then be traced to a driver and hopefully a piece of specific hardware you can disable or install a different driver for.

System interrupts, 0.1%, normal process ?
Hello there. I recently got my new computer and I'm a fresh user of Windows 8. I'm happy and all I was just wondering if the system interrupts process is a normal process, should it be there at all ? It does no harm so far (I think), I just wasn't sure after reading up on it if the complaints were...
