CPU spike causes a buzz sound

Hi there,

I have two problems, which maybe inter related.

1st is: Having loaded Adobe Premiere CS5.5, I was not able to capture my Canon LegriaHV40 video without it being jerky or 'sticking', consequently ‘corrupting’ frames. I also noticed a buzz sound every now and then from the audio.

2nd is: watching a youtube clip, or any type of video media the intermittent ‘buzz’ sound is much more noticeable. Having scoured the ‘net’ for possible answers, it seems that some people have had the same problem and they say it could be the CPU spiking because of a particular program possibly conflicting but none say how they identify the program from the ‘spike’ in the Resource Monitor.

I feel fairly certain that if the buzz sound is cured my video capture will be too but, of course, it may be wishful thinking. Some-thing’s definitely conflicting somewhere but . . . what?

Any pointers, solutions, advice will be gratefully received

Thanks in anticipation

Ciro

Hi Happy Rock,

Thanks for the swift response. I have opened just Firefox, stopped Microsoft Security Essentials and any other processes/services that I know are safe to do. The resultant "buzz" is still there when playing video. There seems to be a 'seizure' in the video footage, too, albeit a nanosecond's worth.

I've attached screen shots of the two places you asked for.

cheers

go here...get your audio driver and install it...
I recommend you get all your drivers while your there then burn them to a cd/dvd just in case you ever have to reinstall a driver you will already have them

I did download latest drivers as advised but found the latest ones were already installed. Downloaded an older version to see if that might help.

First, though, I disabled HP Power Assistant and . . . no more buzz!!!! Hoorah! Dog's bollocks!! Of course, I don't want to be premature and will give you an update a few days down the line to let you know that it's not just a happy fluke! Now to see if my Adobe Premiere video capture works. FIngers crossed.

Many thanks. What would we mere mortals do without you guys?
