[Solved] Strange Windows 7 stutter

I am getting some wierd stutter going on with my pc

The specs:

E4500 Core 2 Duo 2.2ghz
XFX 9800GT
2 HDD's
4GB Kingston RAM
Xcilio 500Watt Goodpower
Gigabyte P35-DS3l Rev 2.0
ASUS PCE-N13 Wireless card
Windows 7 Home Premium 64-bit

What happens is that sometimes while using my pc normally, the mouse will stutter and won't respond for half a second and if there's audio playing, it will distort for that half-second too and this will go on for a few seconds

Here's what I do know for sure:
It doesn't matter what program is playing audio, it will stutter (Winamp, WMP, Youtube)

On some computers it is possible to recreate this audio stutter by going into the device manager and scanning for hardware changes while there is audio playing.

The cpu temps do not go up and the usage percentage in the task manager doesn't spike up either.

In CPU-Z the voltage does not change.

My audio drivers are up to date (Realtek HD Audio). My motherboard drivers are up to date. I've reinstalled Windows 7 twice to fix this yet it still happens randomly.

Any ideas?

Uninstall WinAmp.
Have Windows Task Manager running using the Performance tab. (Also use Option - Always on top so you can see what's going on).
Test and report. Try to reproduce the problem and note if the CPU utilization pegs out at 100% during the stutter.

Then switch to the Process Tab. Reproduce the problems and see if you can spot the process name that shoots up in CPU % column. You can click on that CPU column twice to have it sort if order of % to make it easier to spot

You're welcome.
I actually have a pretty good idea what the problem is but you may find someone else you feel you can better work with.

Also think about turning of indexing or windows backup - just throwing things out.. might be indexing - Also look for a conflict between your hard drive and your audio card - same irq? I had this problem with a conflict with my firewire and hardrive on the same irq...

I found what may be the problem. It seems that everytime I get high network usage from my wireless card, my pc stutters.

Hi There,

I have the same problem.

Windows 7 64 bits ultimate. Intel core I7 920, 12 GB

Tried the DPC Latency Checker, checked mem usage, processor usage, disk activity, etc.

Can't find a problem there. Tried different mouses, wireless and wired usb.

It seems a problem in Windows 7 64 bits usb. I read some articles in different forums.

There is only one workaround that helps and that is to use a mouse- usb to PS2 converter. But my wireless Trust mouse doesnt work on that.

Sometimes its moving fluency and then all at sudden it starts stuttering.

I'm having the same problem. I'm running Win7 64bit, and I'm POSITIVE the source of the choppy video and audio is my wireless card. As soon as I dissable the card the problem instantly goes away. I'm running an Asus PCE-N13 wireless card. If anyone knows of a solution it'd be greately appreciated

hi i had the same problem for ages i have tried all of the suggestions that different forums had but this time it has actually cured the problem

Thankyou soooo much
