Issues with CPU hit 100%

Right.
This problem has been bugging me for a while. My windows 7 machine has been optimised to use all eight cores and every now and then one or more of those core will peek to 100% stalling what ever is using that core at the time. it only lasts for about 1-3 seconds but it gets very annoying that it keeps happening.

nothing is safe from this, anything that is using the core at the time will lock up for a short time, from the media and being that the music i'm running even to mouse pointer leave others systems going no problem. it really pisses me off when i'm about to get that allusive ******* in some game to have the game freeze for 3 seconds only to find i'm the on being shot at.

any ways, hopefully someone know this problem and can help.

if you need to know here are my core machine stats
I7 920
Asus P6t
6Gb triple channel DDR3 1600
Asus 9800 GTX+
Zalman 850W
windows 7 pro x64

also, my brother is running window 7 home premium with a quad core, it is also optimised for all cores and every now and then he will have the same problem although not as much as i do, but then again he doesn't use his machine as much as i do

right

I have avast, malwarebytes and spybot on this machine. it is squeaky clean

The next time it does a freeze i'll note the time and check the event viewer

Device manager reports no issues with any of the hardware devices

gonna start checking the other stuff now.


When all the tasks have been ticked off i'll come back here with my findings :)

What kind of optimization have you done?

From what I've read, dedicating cores to specific tasks is useless because of the default way Windows assigns processes. There is little to no performance gain.

msconfig
went to the boot section, told it to use all eight cores

Hi, you might want to read this about window myths.

that would be easier if i could replicate the error all the time, i'm afraid the issues (although they do come round often) are random.

no, I've done the selective thing several times with clients machines and the one thing that is a must with that is a static problem.

This is why this problem is so elusive. any ways, i think i found something of significance but i need to observe a bit longer to see if this 'thing' pops up every time one of the cores go max or if it only has to do when explorer does a quick freeze on me

I suspect this is an A/V problem like richc mentioned earlier. I would try to disable or better yet, uninstall them one at a time to find out which one is causing the problem. It's the only thing that can cause this type of problem and A/V's are famous for it. The fact that it's happening on both machines which no doubt have the same A/V's installed makes it pretty clear what the problem is.
