@toronaga77 After wide research I can say that this problem is because of CPU. Intel doesn't admit to processor is defective.

I heard that lots of laptops with this cpu has the same problem 

[BJoker1]

exact same problem im having

[whichidisthere]

I have the same problem. But mostly it happens when watching flash videos'. But some times while working on other things too, but ofcourse no sounds then. Have you found out the rootcause? Please let me know if you have any updates... I am planning to go to ASUS to escalate the problem to them, since the laptop is in warranty

[jelons]

@whichidisthere 1) Could you give me more details about your hardware?

2) One thing which can help you is, check which processes escalate the problem, and then, go to the task manager, right on the problematic process, and change "affinity" to be using by one processor (or thread in hiper threading). To determine which process is making the problem, very helpful is "process explorer" (check on google, this is a microsoft tool)

[whichidisthere]

@jelons It is i7 2630QM, 2.0 Ghz, 4GB RAM, 500GB HDD with Win 7 premium. I will try to download "process explorer" and find out which process is taking that load. Did this help you but?

[jelons]

@whichidisthere yes, this resolve the problem but only temporary, just because, you have to set "affinity" on chosen process every time when you restarting the system and you will not know whether the program which you want to instal has problematic process or not.

[jelons]

@whichidisthere So I'm looking for resolve.

In my situation, the problem occur when broken WI-FI HP driver, sends a thousands packages through the firewall of McAfee. And I understand that, it is not an issue of broken driver (I mean the problem which we talking about). This is because "McAfee firewall" takes a lot of processor space what is in my opinion common situation, but behaviour of system or processor is not normal. So this is

microsoft or intel issue.

[jelons]

So, I add, what we have now - the problem is in HP driver

[jelons]

after a question on McAfee forum I got an info from McAfee support that they did a tests and what they found, quote "The driver is polling the network (it's a form of 'keep alive' so that the wifi connection won't drop/sleep). This is generating hundreds of firewall events per second, causing the systems to slow down while the firewall correctly processes those events."

[jelons]

Another issue, that I found, is that, If process takes suddenly large amount of processor space in each of 4 core (8 with turbo boost). For instance

mcAfee process McSvHost sometimes cause such error. But it disappear when I change colligation in task manager for this process

[jelons]

I could also add that mostly this take place while I'm installing or uninstalling new software in WINDOWS 7
