System Interrupts high CPU usage windows 7 64 bit...

[Amandrix]

Hi there, I've seen some posts about this, but nothing helped me.
I'm really asking for help here as my last resort.
I got an Asus laptop K53SC, intel core i7-2670QM with nvidia 520MX.
Problem is System Interrupts starts randomly eating up 1 core to 100%.
I've tried everything, I've contacted Asus support, but their technical level is below 0 (I'm surprised they haven't told me to buy another laptop).
All my drivers are from asus website, windows 7 is 64 bits Dream Spark edition.
Interrupts really start randomly and whenever they want (usually if I play a movie / play games / because of flash player etc...). The thing is sometimes they start after 5 min of movie play, others they did not start after 3 hours of movie play, which is making things harder. You got the ideea.

Technical informations. Ofcourse I've installed latency monitor / windows xperf.
Found out that acpi.sys / ntoskrnl.exe / hall.dll / I don't remember last 1, are causing highest DPC / Interrupts. The amazing thing is that only 1 is triggered at a time. Once is acpi.sys, once is hall.dll, once is tcpip.sys and so on.

I would appreciate really any real help that I might get here, because these interrupts drive me crazy. I've tried all versions of bios, I've tried to dissable audio HD, I've tried almost everything I saw on the internet but with no success. I don't even know what's causing it, I've heard it may be the audio / graphics / usbport (yes, I've remembered, sometimes usb.sys is causing it).

If you need logs, I could try and make System Interrupts pop and run latency / xperf to record them.

Thank you so much,
Kindest regards,
Alin.

Hello and welcome Alin Mate I am no expert on these things and can only suggest some simple things to do unless you have tried these already.

Ok, thank you, any help is appreciate, I will try those things

 

[ICIT2LOL]

No probs Alin they are really the very basic sort of stuff that I use and there is more to be done if these come up blank

First two scans came out empty. I'm on the last scans now, they would probably came out dry as well.
I have a question, can this possibly be a hardware related problem ? My laptop is still under guaranty and Asus support told me to bring it to their guaranty center. But if it's not a hardware related problem, what they could possibly do to my laptop there then ?
PS: after 45 minutes of superspyware scanning (and nothing else, computer was idle), system interrupts pooped up.

I would suggest it probably is hardware related.

 

[Amandrix]

But why it's behavior is totally random ? I did not managed to reproduce System Interrupts for more times in exactly the same circumstances. Internal temperature has no role in this. So is my last option the asus warranty center ?

But why it's behavior is totally random ?

This is precisely what would be expected with failing hardware. Hardware failures do not follow any rules about consistency, repeatability, or what the symptoms will be. Temperature or other external conditions may or may not influence results. The results are largely unpredictable. Software failures tend to be less random.

All tests suggested by ICit2lol came out empty. So my only option will be to use the warranty and I will do so. Thank you everyone for helping.
And yeah, you are right LMiller7, thank you

Absolutely Alin and that is what warranties are for my friend. Yep LMiller has it in a nutshell just because it's new doesn't mean it is perfect and free from failure of any part hard or software.

 

[hache98]

I have same laptop, same problem!

What did they say the problem was at asus?! My warranty just finished and i have the exact same issue you described! I've been googling but i cant find a solution and asus support don't know nothing.. Please get back to me

many thanks !!

Now I am not criticizing but a quicker way to get your problem sorted is to start a new thread and quote the thread you have seen your problem in because it only comes up when you post a reply in this thread and I and the others get a mail letting us know you have a problem.


But it's ok you were not to know that so in future just start a thread and say what the problem is then copy / paste the address of the thread you saw a similar problem in and it will pop up in new posts where it will be seen much quicker and by a much larger number of members / audience


Oh don't forget always - always include all the system specs you can
http://www.sevenforums.com/tutorials/180324-system-info-see-your-system-specs.html

Now you can do that now or just trail along here and I see there is no motherboard listed on the specs mate most important.

It could possibly be a busy spinlock, they usually appear as 100% CPU usage.

Absolutely no problem... laptop was passed through a complete hardware testing, and no problems were detected... only problem was dust and overheating which was normal after 2 years of use... but I had this problem with interrupts when overheating was no problem at all (when it was brand new, no dust in it)...

I really have no logical explanation for why System Interrupts stopped after the dust cleanup... all I did was a format and a fresh windows install, which I did before taking it to the warranty service with no results (after first restart with fresh windows installed, System Interrupts 100%).

I must say I used the same live USB with windows 7 which I used before, nothing different, but interrupts stopped by magic...
So yeah... it's a miracle I must say....

 

[rainerpm]

So?

So the cleaning will do the trick?

Or is it really miracles?

I have an Asus K53 SV and i had the exact problem right from when i bought this notebook and i really wonder if cleaning will help me

 

[ICIT2LOL]

Hello and welcome rainer to both last posts yes cleaning especially in laptops is an essential because of the confined space within and therefore the airflow over the board lye alone out through the "radiator".

Rainer also maybe the laptop was not that well put together from day one mate not every machine comes off the line squeaky clean so to speak.
If you want to see the state of the rad just shine a very bright light into the air intake aperture and then look in through the side outlet vent slots you will be able to access the amount of rubbish if ant there is there. Cleaning that is another matter and we can guide you through that if and when necessary.

Personally I tape a piece of sheer net curtain over the intake aperture on my machines to stop the ingress of particulates and hair etc. Any dust and rubbish can over time build up on the board and other surfaces and cause overheating and / or conduction of current between circuit components.

Sometimes bloatware included with retail pcs can cause strange problems like this.

That's why, like greg I always suggest this:

When ever I am brought a system with the same issues, I always use the Microsoft Sysinternals Suite Process Explorer. I find that it allows me to pinpoint issues quickly. I was using these tools before they were bought by Microsoft. They are a great set of tools. Just a suggestion.

As for the information regarding the dirt and dust the inhabits all laptops, you are correct, they must be clean on a regular basis to keep from overheating, odd things from happening.

Bought by Microsoft? Mark Russinovich designed and developed most of the tools, and he used to work for Microsoft, so he more carried them over with him.
