    CSRSS Using 100% GPU Freezing PC

    Over the past couple of weeks I have been experiencing either severe lagging or complete freezing of my pc. In task manager the culprit seems to be Client Server Runtime Process (gpu 0 - 3d), which is located in the Windows 32 folder as CSRSS, using upto 100% of the gpu. This seems to happen randomly, even when the pc is idle.

    When I use the mouse wheel for scrolling on a website, then the Client Server Runtime process immediately uses the gpu at between 30% and 40%. I turned of hardware acceleration in Firefox, but this doesn't seem to have made a difference. Anyway, the pc will sometimes freeze without a browser open.

    I am also sometimes get 100% CPU from System Interrupts.

    During this time there have been updates from Windows and Nvidia (GeForce GTX950).

    It sounds like you may have gotten some malware; those processes should not be taking that much resources. Download the free version of Malwarebytes https://www.malwarebytes.com/mwb-download install it then run a custom scan include all hard drives on your PC.

    Thanks jgtech. I already use Malwarebytes, it's found nothing. Although a while ago, Windows quarantined a Lodi trojan. Perhaps some malware is still lurking undetected. I'll try a couple of other antimalware progs when I return at the end of the month.
