Like your computer is freezing and bsod? What are your pc specs? What updates have you done? Where are you seeing the cpu usage
no like the process system interrupts is using a ton of cpu usage and bogs down my PC, making everything lag a lot, specs are i7-10700/RTX3060/32gb RAM, updates are sitting currently at latest windows 11, cpu usage I am seeing in task manager
What exactly are you doing to recreate this issue? Is it when gaming? Productivity? Or just overall every time. Any hard drives dying or thinking close to dying etc
Theres a hardware fault potentially somewhere in your system
it does it all the time, it seems to bounce around between 20-40% of cpu, I know I have a drive that's kinda old, but it doesn't really get used too much, it's mostly just for cold storage of files
It's very odd, when I first open task manager, it is sitting anywhere from 30+% cpu usage, just for the System Interrupts process, I've seen it just now as high as 50%, but literally seconds later it'll drop down to less than 10% and stay there until I close task manager and then reopen again
GG @MYHM, you just advanced to level 2 !
most google searchs tends to say hardware fault when it comes to system interrupts but at this point idk. any pcie devices, or usb device acting funky or causing bsods etc
System Interrupts are all driver related. Your best bet is to update all your drivers, and specifically for GPU's to use DDU in safe mode to uninstall the drivers + disable Windows from installing drivers automatically, then when you boot back into normal Windows you install your drivers with the "clean" option for the installer
If you have an Nvidia GPU, then you would want to use NVCleanInstall after you DDU instead of the regular Nvidia driver installer
Alright, I'll give this a shot, other than this, I have no idea what could be causing it, maybe my USB Hub?
I do have a ton of stuff plugged into my pc, maybe something is messing up, idk
I'd personally recommend using Snappy Driver Installer Origin (SDIO) which is an open-source driver installer app. It's the only one I trust because it's open source and all it really does is just pull drivers from the manufacturer sites
this shows I have a bunch of updates/better drivers, so I'm going to go ahead and install everything it has, see if maybe that fixes the issue
I can see at least 2 items that say driver not installed yet, so we'll see if that helps
okay this didn't work, I get E000248 on everything
I don't know what E000248 is
google doesn't seem to either
Where are you seeing this error?
Ah I fixed it, it was due to me disabling device driver updates via group policy
on SDIO, next to each device
now I got 2 error 103, on ASUS USB-BT400 and Intel cAVS
Just to make sure, you downloaded the ZIP, extracted it to a folder, and then ran it from inside the folder, correct?
yes, downloaded from the link you sent me
it gave me a list of devices, and said drivers are either missing or out of date, initially didn't work as I had disabled driver installation in group policy, (oops) now it installed everything but the two devices listed above
Hmm well that won't pan out it seems
You can at least use the tool to see the name of the devices you should update, and then you can navigate to the manufacturer site manually to get the necessary drivers
well for the cAVS it wants me to install an older driver thats more optimal
and the bt400 I can just remove, I don't need it anymore, so that solves that issue
Actually between driver updates and removing the usb, it seems to have helped the issue quite a bit, system interrupts is now down to under 10%
right as I said it, it jumped back up to 60%
I wonder if me starting task manager is what is causing the spike, which is why it dips almost immediately back down
GG @MYHM, you just advanced to level 3 !
which would also be why I am unable to see it in process explorer going so high
yeah screw it, as solved as it's going to get I think
