Windows 7: Lag Spikes when connected to the internet?

Hi again,
today while watching a program on 4oD and I was getting these lag spikes every 30 seconds to a minute. It's definitely worse when I'm doing things that use higher internet connection.

damn.. i'm not certain how to further t/s this. Some problems are a pain and pesky. Hopefully someone else can throw in some advice.

Thanks for all your help, it has really improved after doing what you said! I also think I have fixed it by accident! I've just overclocked my CPU from 3.3GHz to 3.6 (Going to 4.1 when my new cpu cooler comes) and it hasn't happened again since!

Again thank you for all your help, I really appreciate your time!

good to hear! you can mark thread solved, thanks.

I am currently having a major issue with this. Through previous posts I used the DPC Latency Checker and through process of elimination found that, what a shock, it's my wireless network adapter (Atheros AR5B93 Wireless Network Adapter). Drivers are currently all up to date and working properly. Lag is pretty bad when using anything internet related and listening to music, just distorts like crazy. Any help would be appreciated.

Please post your own thread in the future. I have actually discovered what was ultimately causing my problem, it was McAfee internet securities feature 'NetGuard'. I have since stopped using McAfee and started using Microsoft Security Essentials, and now I have no problems at all. I have no viruses, and no more trouble with lag spikes.

Sorry about that, new member and all.

Surprisingly I do have the McAfee Internet Security running while experiencing these spikes. I did just however re-new my subscription with them for another year like 2 days ago so I wish it didn't come down to terminating my service but if it fixes the spikes I am all for that. Do you suggest just turning everything off or completely un-installing the software all together to fix the issue ? I just got so frustrated by the spikes I bought a netbook for all my internet needs while my laptop plays music and what not. Pretty lame and costly solution but seems to be the smoothest sailing solution at this time.

You don't NEED to completely remove McAfee but I would recommend it as there are much less resource heavy Security Software Packages. If you want to keep McAfee try turning off NetGuard to see if it fixes the issue.

Disabling NetGuard....yup that's the answer.....many thanks!
