Windows 7: Computer stuttering randomly. And high Latency on windows 7

Computer stuttering randomly. And high Latency on windows 7

I recently formatted my hard drive and did a clean install of windows 7.

Lately ive noticed that while watching youtube videos or listening to music in windows media player, ill get these random stutter moments where the computer just seems to slow down for a second. It makes my audio/ video/ and mouse all stutter.

I ran DPC Latency checker and found that at the moments I had stutters, the latency checker was spiking up to max in the red.

I read around online that it is the network card that causes this, so i disabled my network card and the latency checker remained in the green.
Then I tried reconnecting my internet via wifi while the network card was disabled, and once again I started getting spikes.
I also tried updating my network card to the latest driver and now its even worse....

can someone please help me? These random stutters are starting to get annoying.



Also a side note:
Ive noticed that if the driver is enabled, and im not doing anything network related its all fine. But once I do something like load a page or load a video, thats when I start to get the random stutters.




Update: I ran latencymon and I found that flash player is causing many hardpage faults, and that a driver called ndis.sys - NDIS 6.20 driver is causing my latency spikes.


Here is the summary report
____________________________________________________________________________________________________ _____
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 executed by a driver running in your system appear to be executing for too long. At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. 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 0:04:44 (h:mm:ss) on all processors in the system.

Have you checked your flash player to make sure it's up to date and that the hardware accelerator is enabled.

Yes my flash player is up to date and hardware acceleration is enabled.

I dont think its a problem with flash player though cause I get the stuttering even when the browser is closed and im just watching videos on windows media player.

Same Problem - Do you have a Dell?

I started having the excat same problem, I have a Dell XPS with all the good stuff, exactly the same problem. I did some searching and noticed many dell people, particularly in the last 2 years are having this problem. I tried disabling everything and as long as wifi is going, its there. Truly frustrating.

For me, i can actually hear two successive "clicks" at the time when my computer stutters.

I've written so many people and noone seems to be offereing anything except, update drivers, scandisk, bios updates, etc. I did everything. Updated everything from intell site, dell site, microsoft, etc..>Shut down all processes except microsoft processes and still happens.

I'm curious if you learned anything new?

I do not have a dell. I have an HP pavillion. My problem happened when I installed windows 7 onto it.

I honestly gave up a long time ago, ive tried asking professionals, tried going to multiple forums, tried sending it to geeksquad to fix, no one has a solution. Its apparently just a problem within the windows 7 kernel and has not been fixed yet. I think it might simply have to be that my processor isnt compatible with win7 since its kind of old (even though its high end). Im gonna try reinstalling win7 maybe and see if that helps, if not then im just going to buy a new computer and stay the hell away from HP and dell. Since all they do is put crapware on computers that mess them up.

Hi,

Your'e giving up too quickly. If you want to reinstall, then do it without the crapware using this tried and tested technique:

Clean Reinstall - Factory OEM Windows 7

Once installed and activated, let Windows perform all the updates, and then see if your system is more stable.

Post back if you need more help.

Regards,
Golden

UHmm im not giving up too quickly. Ive been trying to fix this for months now. I have a lot of games and other important files on my computer and I dont have the time to back them up and do a clean install as im really busy with school. Ive just learned to live with it. However if anyone knows of a magical solution out there that can fix ndis.sys causing high latency then please by all means reply to this thread. xx
