Computer 'hiccuping'

[Hoov]

In the first post he mentioned have two 100mm fans one blowing into and one pulling out. Even if they were flowing straight thru the computer, that should still be enough airflow to keep the temp down, unless the way everything is installed and situated is creating a dead area, but when he replaced the side with a piece of plastic the problem should have come back.

It might be possible that it is a heat problem. Might have to replace the side with a piece of Plexiglas and use some canned smoke to check the airflow in the case.

But that just brought another thought to mind, your PSU, is the fan dumping the heat into the case or expelling it outside the case?

Ive got 3 100ml, theres one on the side of the case - i mean its a thermaltake case and all optional fans are in and its not a mess of cables in there im assuming its cool.
Im assuming the PSU is dumping it outside, can feel the breeze out the back where the fan is.
ive since stopped the fan on the side of the case, as it was the only one plugged into the mboard, however it still does it.
I guess the next thing to do would be to pull the entire thing apart (cept leave the mobo seated) and rewire everything in -if its only happening every few hours and still as a hardware interrupt and DPC then could it be like a reset button or a fan just not quite in the plug properly?

[Hoov]

The fan on the side of the case, can you unplug it from the mobo, and cover it over so there is no airflow thru it?

[Taz]

Yep have been doing that for the last day, seems to make no difference, still unplugged

[Hoov]

Is there anything else mounted to the side of the case? Do the wires to the fan touch anything?

[Taz]

Doesnt look like it no, and it happens with the fan completely off the side of the case as well.

[Hoov]

I just had another thought. Take one of the other two fans and unplug it. Put the side back on and see how it runs that way.

[Taz]

Sorry bout late reply thought i already did 
Tried every fan combination from swapping all of the around position wise, then direction wise etc and for the hell of it put them all inwards then outwards, then only one on in each slot - no difference

[Hoov]

There is something we are missing. When you take the side off, does the internal temperature change at all?

[Taz]

It does up about 1-3 deg but i have had a fan on the open case full blast a good 5-6deg cooler than normal and it still does it, and when it does hiccup/stutter i notice that the temp doesnt budge so if it is temp caused its beaten me!

[Hoov]

How good are your fabrication skills? Can you make a side out of Plexiglas? That sounds about like the only thing that is going to make a difference.

[Taz]

A better question is how lazy am i haha
Went case shopping the other night and i think i might just replace the case with the new coolermaster stormtrooper case or the level10 case if im feeling rich, and replace the wlan card with a top shelf one from another brand - so if its either or causing the problem HOPEFULLY this will solve it and i can get on with it!

[Hoov]

Those are some interesting looking cases. But I would do some longer term test to make sure it is definitely the side causing the problem.

Hello, I dont know if you resolved this. But i had the same problem. only my hiccup was slightly less severe. For me the stagger would really annoy me when playing audio. it would sputter just as you described.
I was able to resolve my issue in part. Meaning i dont know what the cause but i have a suspect. and have greatly reduce the problem to a rare event.
I personally think it's the Seagate hard drives. i upgraded to 2x 500gb HDs in my laptop. and noticed this problem not long after. However i cannot say for sure this is the problem because my fix was not to remove the HD's.
Here are my suggestions as this is what i did.
First go to Device manager and Remove your display driver (delete) let the basic VGA driver install. see if that helps. THen do this one by one with all drivers you can. and see if your problem continues.
Next try a clean install with one harddrive, see if the problem persists.
For me, i removed one of my harddrives, did clean install, and then added the second drive later after system was up and stable. The Problem is mostly gone with a rare occasional "Hiccup" when downloading a large file.
So in my case, it could have been either the HardDrive or the Network card sharing interups.
But if you think about it, it would make sense that it's the HardDrive.
When the system needs to spin up the HD and transfer data, this is tying up the bus, do to some error. When i reinstalled, the HD controller is now acting right and not hogging the Bus. atlest this is my thinking.

I would also suggest using Process Explorer to check for excessive CPU cycles by a number of things that Task Manager does not track.  I had an issue like this in the past with a system, and it took weeks to track it down until I started tracking CPU utilization and found almost 50% of the CPU was being used by system interrupts which do not show up in Task Manager.   Clearly a hardware issue which I finally tracked down to a shorted circuit board in my floppy drive.  I disconnected the floppy drive and the problem was gone.  I'm not suggesting that your problem is similar, but with persistent issues like this, Task Manager may give you insufficient data to track down the problem.

So this "Project Explorer" is software that will let you know how your computer system has been working, and lets you understand the machine's useage more completely? 

Six months ago, I replaced my Windows XP hard drive, and it no longer has the "utility manager" for some reason. I do need a new utility manager.

Would this be the thing to get?
