Windows 7: Getting System Interrupts

Getting System Interrupts

Hi masters. Within 10-20 minutes after booting my whole PC starts to lag very heavily. I checked the Process Explorer and found "System Interrupts" consuming about 25 % of CPU. I had all the latest drivers but I have rolled backed to older driver for the GPU for now thinking that might have caused the problem. I have uninstalled ESET Smart Security and ran the ESET Uninstaller, and afterwards installed MSE. I have also removed Alcohol and SPTD along with it. But none of this has solved the problem

I am searching for xperf so that I could provide more information here, but can't seem to find it.

Please help. I will be very grateful

You can use apps like SIW2, speccy, everest, etc to get the system specs which we do need.

Sysem interrupts are almost always not the cause of lagging. Sometimes it is an errant driver. Use this free app to test yours. DPC Latency Checker

Hi thanks for replying. I think I have solved the problem by uninstalling Diskeeper 2011. It's been almost an hour now and till now I am seeing no lag, previously I could barely keep the PC on for more than 10 mins. That's strange because Diskeeper 2011 is running fine on my other pc. Also thanks for PC Latency Checker it might come in handy in future.

Thanks again.

Hi I think I should inform here that although Diskeeper seemed to be the cause it was actually caused by a recent update to Tune Up Utilities 2011. Tune Up started disliking Diskeeper after the update so I rolled back to the version of TU that was working properly. Now I have both Diskeeper and TU running together.

Thanks for reading.

Wrong Info read the following post for the actual cause.

Wow! it turned out that neither Diskeeper nor Tune Up were the culprits. After a few hours I started getting the same problem again. So I got XPerf from MS website, and after using XPerf I found out that it was my ethernet drivers that was causing the huge CPU consumption. So while it was lagging I disabled the drivers from the Device Manager and as soon as I did that the CPU process went to normal. [IMG]

Now I have uninstalled the driver and let Windows install it automatically. Everything seems to be working fine now. Thanks for reading and hopefully I have resolved my issue this time.

Also thanks zigzag3143 for DPC Latency Checker. While it was lagging I ran DPC and it clearly showed that there was something wrong. Although it can't find the driver itself it helps a lot in such situations.

System Interrupts
Hello! I have constant 8% CPU usage in Windows 7. It does not show up under any particular process in Task Manager. Resource Monitor says that it is System Interrupts. I suspect this is a driver issue -- is there a way to get more detail on what is sending interrupts to the CPU?
