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

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.

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:

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:



Could it be "normal" for my specs?

System Manufacturer	Hewlett-Packard
System Model	Compaq Presario CQ61 Notebook PC
System Type	x64-based PC
Processor	Pentium(R) Dual-Core CPU       T4400  @ 2.20GHz, 2200 Mhz, 2 Core(s), 2 Logical Processor(s)
BIOS Version/Date	Hewlett-Packard F.20, 13-Oct-09
Installed Physical Memory (RAM)	4.00 GB

Name	NVIDIA GeForce G 103M
Adapter RAM	512.00 MB (536,870,912 bytes)
Driver Version	9.18.13.697

I uploaded another capture again here, if you can't see the problem I give up and try and bare with it, I bothered you enough, sorry.

[MagicAndre1981]

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?

I disabled it and now the CPU graph is more diverse ranging from even 15% to 60% so I think it's okay .. Hope it doesn't escalates up to 100% again where I can't even use the mouse. Thanks for your help!

[harekowicz]

Hi guys!
I have got similar problem with my DELL XPS 15 l502x - high DPC spikes.
Interesting is that when I have spikes and change my Power Plan spikes disappear for short time - then they come back.
Can you have a look at my etl file and advise me what to do?
Thanks!

Here is url : http://www.speedysha...C-Interrupt.etl

[MagicAndre1981]

the trace is incomplete. Do you run LatencyMon, ProcessExplorer or reMon the same time?

[harekowicz]

Oh I am so sorry - you are right - I run LatencyMon at same time, here is a link to correct file:
LINK

[MagicAndre1981]

You have

Total = 144 for module Wdf01000.sys
Elapsed Time, >     1024 usecs AND <=     2048 usecs,      2, or   1.39%

Total = 36937 for module ntoskrnl.exe
Elapsed Time, >     1024 usecs AND <=     2048 usecs,      7, or   0.02%

Total = 296 for module nvlddmkm.sys
Elapsed Time, >     1024 usecs AND <=     2048 usecs,      1, or   0.34%

Total = 1521 for module tcpip.sys
Elapsed Time, >     1024 usecs AND <=     2048 usecs,      1, or   0.07%
Total,                                                  1521

You have some some spikes. The tcpip.sys comes from Chrome, The kernel has some Power management operations. Which powerplan do you use? Also try to disable Core parking. Does this fix it?

[harekowicz]

I use High Perfomance power plan. I disabled Core parking but it does not fix anything
Also I am uploading LatencyMon results. O and on strange thing: every time I open minecraft.exe my computer seems to be working better - peaks are really rare.

[MagicAndre1981]

which issues do you have when you have the spikes? Audio and video drops?

[harekowicz]

Yeah - audio and video drops and distortion, even mouse pointer has issues!

[MagicAndre1981]

make new traces. Maybe one of them includes more data.

[bryizzle]

Hi Magic Andre and everyone else -

I've sifted through countless google search pages, Microsoft forum threads, Tomshardware forum threads, any forum that I could possible find and have ended up here...

I'm hoping one of you can help me smooth out my PC problem I can't get away from.

I have constant high spikes in CPU usage; LatencyMon blames it on USBPORT.SYS.

I have constant audio and visual problems (cackling and FPS loss) during these CPU spikes.

Using Windows 7 Ultimate
500w powersupply
MOBO: Biostar A870U3
CPU: AMD 965 BE Deneb
Graphics Card: Sapphire Radeon HD 6870

Here is my .etl file - Use your Magic!



If you need any other information that would help you help me, please let me know.

I feel I have every single driver updated, I've reformatted a few times, I've updated every driver manually and also used DriverGenius software to upload all the drivers. My computer may seem to be fine for a little bit but the problem will always come back.
