Windows 7: New Installation- Windows 7 Stuttering/Lag

New Installation- Windows 7 Stuttering/Lag

Hey All,

I am having a pretty frustrating issue I am hoping someone can help me with!

I own a MacBook pro that is dual booting Windows 7 with bootcamp. Up until about 3 months ago I haven't had any issues. I run my Windows 7 partition about 99% of the time. However, in late November I noticed my computer would start to stutter. That is, no matter what program I was in (Firefox, Word, Outlook, watching a movie..didnt matter), what ever action I would do would freeze for a second or two followed by it catching up to itself. This is the case for the mouse if I was moving it, a webpage scrolling, or typing an email response.

I originally thought it was just a virus and decided to wipe my hard drive and just start over. I reinstalled Windows 7 again, and I instantly knew my problem hadn't resolved itself. It is incredibly frustrating and is definitely affecting my productivity.

I have tried everything I could think of to fix the problem- updated all the drivers I could think of, reinstalling the operating system again, etc. Does anyone have insight as to what might be causing this and what I can do to fix it?

Thank you!

EDIT: This stuttering problem is also happening on my Mac partition (although to a lesser extent), leading me to believe it may be a hardware issue. I ran a couple of different hard drive tests, but they all came up as passing. Any other hardware that might cause this?

Check whether you have a DPC latency problem. Run this latency checker. If you have a lot of red spikes, see what it tells you about the cause of the problem. If it is all green, then it is another problem.

What did you run for hard drive tests? It sounds like a failing drive or a drive with bad blocks. I can't be of any help on the MAC end, but a program like hard drive tune can scan your drive through Windows and show you a visual map of any defects found.

@Whs: Here is a screenshot of my DPC Latency checker:

I assume being in the red the majority of the time is not a good thing? What could be causing that? I am also not sure why there was that extreme spike- that absolute maximum is super high.

@Fred Garvin- I will give that tool a shot and let you know what it finds!

This does not look good at all. First have a look in device manager whether there are any yellow flags. But even if your drivers are all up-to-date, there could be one that is misbehaving. Hard to tell from here. It is a matter of trial and error and a good portion of luck.

Since I have no idea regarding a Macbook, I am afraid that I will be of little help on the details of the trouble hunt. Maybe the guys on a Mac forum would have a better suggestion.

Run a Disk Check in Windows to see if it finds anything.

Couple of updates:

FliGi7- Ran a disk check when I first started having issues, ran a second one today. No errors found.

Fred Garvin- Finished running all the tests I could find on Hard Drive tune, but they all passed.

In terms of testing the drivers, is the best method just to disable them one-by-one and watch for changes in the latency checker?

It could well be a hardware issue. MACs, like other Apple products, tend to use propietary hardware. Did you have this problem prior to you installing Bootcamp? You might be better off going to a MAC forum that specialises in Bootcamp issues.

I actually installed bootcamp and had it running successfully for quite a long time before this issue cropped up. Its sudden appearance leads me to believe that it is either a hardware issue or some driver incompatibility that came as a result of a Windows update or something funky.

Did you try a memory test with memtest?
