Default Every 5 seconds, the CPU stutters for a split second

Just like the title says. Every 5-10 seconds, all operation on the computer will "stutter" for anywhere from a split second to a second or two. If I'm playing something like Starcraft 2 online, everyone else sees the "This player is lagging" window if it lasts more than a split second.

I had this problem over a year ago, and it magically went away... I think someone hypothesized that it could be my north or south bridge over heating or something. But what is weird now is that it happens as soon as the computer is restarted. Before, it took a while to "get going".

This all started this morning when I was playing SC2, and everything started to stutter. I opened task manager and there was this random program in there that I closed and it seemed to help... but now there's nothing I can do to help.

I took my computer outside and blew it out with compressed air an hour ago, and my hard drives are 0% fragmented.

Anyone have any ideas? Thanks!

well, forst of all drop everest in there and do check. if youre not using the gpu, does it still stutter?

could be anything, from a going drive, to some software mishap.

Just sitting on the desktop it still does the stuttering. I've got Everest on my computer now, do you want me to run the stability test? Or what exactly would you like. It isn't popping up with any immediate errors.

I did an "erase and install" of Windows 7 maybe 4 weeks ago, if that helps.

hmm

you got to start with the basics. dont think its mem errors, as it should blue screen/crash but still

Ultimate Boot CD - Overview

after that use HD Tune website to check the drive.

also HdTach

unless there is something taking a heavy toll on the cpu/ram usage.

if nothing there, keep checking.

Use Ctrl + Shift + Esc to open Windows Task Manager.
Select the Processes tab and observe which process is using the CPU at the time of the stutter.

I had a similar problem 3 weeks ago but my was caused because i updated my wireless driver from the windows update thing. I would get none stop hesitations all the time. i had to roll the driver back on it to fix it. think about anything you installed or changed just before this started to happened. did you just install sc2 on your comp? any driver updates? how are the temps on your cpu/gpu/mb..?
