How to get the cause of high CPU usage by DPC / Interrupt

1,451 posts in this topic

Comes up with an error: "xperf: error: -on: does not expect 4 argument(s)."

What am I doing wrong? XD

@Furyclaw

we posted the same time.

The new tarce shows you have high CPU usgae caused by he ACPI driver. ACPI.sys!OSNotifyDeviceWake looks like Windows has issues to enable devices after they were send to sleep. so disable the powersaving options in device manager for all devices.

@Andre

I will definately try that out when I get home. Power management is getting to be an annoying thing in this new rig.

Will get back to you with the results. Thank you for your patience and expertise.

Not many good news :(

I came home and tried to disable power saving on all my units that had the option in Device Management. This didn't have any difference. I also managed to get my bios updated to the newest version available on the website, but this also have not proved useful.

Still sitting at 33-36% CPU usage when just having a webpage up. are there any more steps we can do to resolve this?

yes, disable the battery or remove it and only use AC power.

I removed it and the CPU still remains at a minimum of around 60%

I've just installed a brand new copy of Win7, in a desperate attempt to make this s*** work. Can barely play BF3 with this rig at 1368, Low Gfx.

Same problems are occuring, but might have moved location. Hopefully you can help. Working on installing new drivers as we speak.

it is the same APCI issue again. ry to switch to the powerplan "High Perfomance". this disables the power saving options. Does this fix the issue?

It changes nothing i'm afraid. Still getting interrupts.

Would a faulty psu cause this? Its quite old.

Here's all my hardware as listed by my order reciepts, what my PC lists, all that.

P8Z77V-LX MOBO, 1502 BIOS version.

i5 3570k, No OC.

Corsair XMS3 1600MHz 16GB Vengeance CL9 (4x4Gig set)

Chieftec Super Series 750W PSU (Modular)

Gainward GeForce GTX670 2GB GDDR5 PCI-E

Razer Anansi keyboard.

Razer Deathadder 3.5G

Steelseries Siberia V2 Dig.Surround.

the PSu is fine.

Change the PCIe slot of the GPU. Does this help? Also look in the BIOS/UEFI if you have an option High Precision Event Timer (HPET). Change it's state and look if this fixes anything.

Changed from top to bottom PCIe slot, no change.

Changed HPT (HPET) from Enabled to Disabled. No change.

=( This is getting frustrating xD

But I really appreciate the help.

Right. I'm really considering reverting back to my old system and RMA this MOBO. My friend was experiencing some of the same issues like this, and he sent his kit in, and when the new one arrived he saw none of the errors. When the new stuff gets here I will try again. Really can't see what is left that is causing the problems.

We've so far tried:

Power management settings. BIOS and Windows.

No USB devices connected vs. all connected.

Different GFX card. and different PCIe slots.

Brand new install of Windows.

only 1 spike between 256 and 512µs. So removing battery fixed it.

ok. Please reply here when you get the new Mobo and tell us if it is fixed or not.

But the CPU still remains at over 60% all the time, I don't know what's the average but I was told that 60% is very much having opened only Firefox, Chrome, a small editor and Explorer

I dont know, I still have the System Interrupt activity at 0.5-1% usage all the time...

I've uploaded a clean file with no games running:

the trace you gave me doesn't show the CPu usage. you must capture the trace at the time you have the issue ;)

this time it is again the nVIDIA driver with 2 small spikes:

Total = 9293 for module nvlddmkm.sys

Elapsed Time, > 256 usecs AND <= 512 usecs, 1, or 0.01%

Elapsed Time, > 512 usecs AND <= 1024 usecs, 1, or 0.01%

do you have an audio or video glitches caused by DPCs?

That's the problem, it's not about spikes, it's about a constant high CPU usage:

Removed: Malware

Could it be "normal" for my specs?

the trace you gave me doesn't show the high CPU usage. Your 80 is idle for 80%.

But I can see that you use ProcessHacker. Inside the tool click on Hacker->Options->advanced and uncheck the option "enable cycle based CPU usage". Now restart ProcessHacker. Do you still have the high CPU usage reported?
