System Interrupts eating up around 30% CPU. RRS feed

  • Question

  • First of all, I'm not very computer smart even though I spend alot of time on them. I recently upgraded to a better gaming computer, and all was fine for the first week or so untill it started getting interrupts and jolting the performance, I've searched online and found it's probably something todo with dxgkrnl.sys as I ran an xperf or whatever it is through command prompt and that -seemed- to be the problem, but I don't know much about it. I'm gunna give as much information as I know and the xperf file, if anything else is needed let me know, and try and use lamence terms as much as you can, I know very little technical terminology.

    Windows 7 Home Premium 64 bit

    Intel Core 2 Quad Processer Q8300

    NVIDIA GeForce GT320 1024mb

    4GB DDR3 memory

     

    I don't think it's caused by overheating or a hardware problem because it's new and worked fine for a week or so, but like I said, I don't know how it all works.

     

    This also happens for some reason on the Ultra settings of World of Warcraft, but I don't think it's related to the system interrupt problem, however, input on this would also be nice.

    Any help will be increibly appreciated as this is quite frustrating to have to go through with something I bought less than a month ago, thanks in advance for any help.

  • I can see that the NDIS.sys is causing the issue. THis means something with your network is causing the issue. Are you using the latets driver for your Realtek PCIe GBE Family Controller and 802.11n Wireless PCI Express Card LAN Adapter? Are you running a Firewall or something like this? if yes, uninstall it and check again.

  • Well I installed the latest drivers for my Realtek PCIe GBE Family Controller and disabled the wireless connection as it's the same device and it seems to have halted interrupts as soon as the drivers were updated. The only firewall I have running is Windows so I -suppose- that wasn't the problem, the System Interrupts still hovers at around 4-7% but I'm guessing that's about normal. Overall, it seems to have worked perfectly, Thanks Andre!

    ok, 4-7 % is normal. Great to hear that you fixed it.
