I’m not sure if this thread is dead or not, but if someone can help me I would greatly appreciate it. I am having the same symptoms and problems with my cpu spiking in a “cyclic” pattern. This problem has been plaguing me for a while and I have taken a lot of advice from several bulletin boards and this thread particularly trying to figure out what exactly is happening to my processor.
The more programs running the higher the spikes get with each additional program, until I eventually I have so much lag nothing works properly.
This problem only occurs when I am using Windows Live Messenger Video Call. I have re-installed my sound driver (Sigma Tel C-Major Audio), I have updated windows to XP Pro SP 3, I have reinstalled Windows Live Messenger ver. 2008 (build 8.5.1302.1018), and still the spikes remain. It doesn’t matter whether video is going or not, as soon as the sound starts the spikes start.
Process Explorer helped me to discover what exactly is causing my cpu to spike. It is something called:
If I suspend the thread in the process explorer program, sound ends and so does the spikes. And when I resume the thread, sound resumes and so do the spikes.
I'm not sure how to post the snapshot I took of the process explorer graph, but it looks just like the spike pattern of MattRM above, (only my spikes are upwards to 29% - 33% each spike) every 2 seconds, just like above. ( However, I did add the picture as an attachment if that works). These spikes are really annoying and basically stall my computer when I run video with the sound connection. And if I am running any other program that requires additional cpu usage (especially games), my computer lags so bad nothing works. Not even the video call.
If anyone can tell me what is doing this and how to correct and stop this process from eating up so much cpu usage, it will be greatly appreciative. Thank you in advance.
