Shuttering within windows. Especially when application running

[nshade]

Hi guys,

Hopefully i am posting this in the right forum. I really need help here.

Last month, i had this problem where the performance of my PC was acting weird. I ran the game like Warframe, it shutters when it loads something. I thought it was due to memory issue. I open the web browser, it's the same thing. I know it shutters because when your mouse moves around, it pause for 0.5 sec, like it skips a frame. It happens often when i am opening an application. So i thought it was an issue with the HDD, i ran scandisk, found no error or bad sector. Strangely, the issue was gone.

As of last 2 nights, the problem came back. I noticed massive shuttering when i play games. Often happened when it is loading something. Not only the game shutters, my voice chat got affected as well. My friend told me, my voice chat was breaking up. I'm pretty it's my whole system. The mouse pauses for 0.5 sec and then normal, then repeats for everytime something is loading.

I reseat my memory, it went back to normal. Then the next morning, it reoccurs again.

Today i just watch youtube video, problem reoccurs.

These are what i have done so far.
1. Ran anti-virus, nothing found.
2. Ran spyware nothing found.
3. Ran scandisk, no error.
4. Ran memtest via windows 7, no error.

This is my spec and windows.
Windows 7 Ulti (6.1, Build 7601) Service Pack 1

MBO: P67A-UD3-B3
cpu: Intel® Core™ i5-2500 3.3GHz
Memory: 8192MB RAM (kingston 8GB)
GPU: GTX 970
ssd: intel 250GB
hdd: WD black 2TB
PSU: Silverstone 600W 80+

Apart from anti virus update, windows update, firewall, steam and anti spyware update, i did not update anything else.

I received suggestion to run more test. Mainly the test app from DPC latency checker and LatencyMon.

Here are the pictures.
Test result (pic uploaded to imgur)

I believed these result aren't good. I am not sure where to start now to troubleshoot this.
Please, I need your help.

Basically what the latency checker suggested. Turn devices on/off to single out the problematic component. An alternative would be to run your pc in safe mode, and from there start enabling devices one by one to see what the problem is.

 

[Greeko85]

What are your system temps like? (sorry I can't check your result-work blocks image hosting sites)

Thanks Gyustarr and Gyustarr for the reply.
Hmm, 1st time posting in tom's hardware. Can only use "submit answer"

I tried in safe mode, there was no issue. It runs like normal, the mouse did not pause. Only thing is web browser feels slow but most likely display driver wasn't loaded.

I have tried the following:
Disable network, same issue
Nvidia audio, same issue
realtek audi, same issue
USB, same issue
DVD, same issue
COM & LPT, same issue
High def audio controller,same issue

As for the temp, i used HW monitor:
CPU for 4 cores: 74-80c(80 for package)
mbo: 68c
GPU: 62c

Any other way i could share picture with you?

Picture was showing this.

DPC:
Some device drivers on this machine behave bad and will probably cause drop-outs in real-time audio and/or video streams. To isolate the misbehaving driver use Device Manager and disable/re-enable various devices, one at a time. Try network and W-LAN adapters, modems, internal sound devices, USB host controllers, etc.

CONCLUSION
_________________________________________________________________________________________________________
Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.
LatencyMon has been analyzing your system for 4:13:55 (h:mm:ss) on all processors.

MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.

Highest measured interrupt to process latency (µs): 12143.434720
Average measured interrupt to process latency (µs): 3.241079

REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.

NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.

Process with highest pagefault count: ekrn.exe

Total number of hard pagefaults 79705
Hard pagefault count of hardest hit process: 30562
Number of processes hit: 66

I will do testing again tomorrow. I will reinstall my driver and see the result. Strangely, before i went for my dinner, I shutdown my system for an hour. Then came back to do more testing, ran my game, no issue this time. I will do again and post the result of latencymon.

I'm looking at your cpu temps-74-80c was that at idle or load? If it was idle then you are more than likely facing a thermal throttle issue.

It was load. That's the maximum when i was playing Warframe.

Well... this is bad. During my testing, there was no shuttering, so i continue playing my warframe. As i last checked my temp from the CPU, it was only 83c. The shutters happened then the display goes blank screen, and the machine hang with looping sound. I know it hanged because when i press caplocks, there was no response. The reset button did not work so i had to do hard shutdown. Few minutes later, it happened again.

I had to open up my PC, reseat everything except my CPU. Only then it can run as normal. Today, i tried to power it on, there was light, and bios was loading, then the machine powered off. Turn it on again, it can run as normal. I noticed when i play Vermintide 2, the FPS is less than before.

I doubt that anything related to driver or software could do that. The only question is... which part of my component causing the problem. May also relate to PSU too.
