CPU spikes every 30 seconds.

To the OP, why even use the Task Manager when you can use the Resource Monitor as its Vista ?.

I had pointed that out, there's even a link to it in the taskmanager... hehe

It doesn't really help, I can't pinpoint the resource that was making the spike with it. Perhaps I was doing something wrong but I found process explorer more usuful

I've also just tried plugging the card reader in to my old PC and thats idling fine at 0-1% cpu without any spikes at all. Atleast I know the spikes are USB related. Not sure how to fix it though!

Could try installing the latest Intel chipset / USB drivers?

68 processes running?! I would begin by clearing up msconfig start up list.

Thanks for the replies guys. I have installed the latest P35 chipset driver but its still giving me the 25% CPU spike

I have plugged in 2 more USB sticks and the spike has increased to 45%, so it would appear that I just wasted a load of time plugging my card reader in to my old PC and making all the wires nice and tidy to leave it in there as I thought that was the main problem.

We sorted it

It was the Intel RAID Monitor (IAANTmon.exe) that was querying the Plug'n'Play service for information on attached USB devices over and over and over. God knows why. Updating to latest version of Intel Matrix Storage Manager solved the problem.

Nice one.

Sorry to bump an old thread, but I think I have the same problem. How did you find out what was querying the Plug and Play service?

I didn't ask what was querying the plug and play service. I asked HOW he figured out what was querying the plug and play service.

NathanE · 13 Nov 2008 at 09:29

I used Sysinternals Regmon. Set it to monitor the Plug n Play registry locations and then I found that it was querying a few devices over and over. Then I got a hunch and became convinced that the PNP service wouldn't just be doing this for fun... it would need some other application to be making those requests. So I set about killing a process at a time. In the end by process of elimination I found that the PNP service stopped querying those devices over and over when the Intel RAID Monitor was terminated.

So upgraded that to latest version and all was fine.

Thanks! I think I've pinned it down. I did something I've been meaning to do for a loooong time...

I uninstalled Norton.

Er where would I find these?

Was the Intel RAID monitor part of the Intel chipset drivers?

What the hell do you people run on your machines? 60+ processes after a reboot?

im running 30 currently with programs running, get tidying folks!

Going to now! Got 52 processes running now. But that does include Opera, Launchy and Winamp. Are the sites that have XP service info also useful for Vista services or do I need to google new sites for this?

I think the black viper one has a vista guide too, though the website isnt working for me at the moment

MarcLister · 20 Nov 2008 at 18:02

Yep. I'm on it now.

Probably maxed the site out!

It's installed as part of the Intel Matrix Storage suite which includes both the RAID driver and a monitoring utility/service. It was the service part of that utility which had a bug in it causing high load for the PNP service.

Ta. Seems like I've got the latest chipset drivers from the Asus site (P5Q-E) so I can't really explain my jerky mouse movements. Found something online last night suggesting that re-installing SetPoint with NOD32 disabled might work. It didn't.

Still suffering jerky mouse movement after new drivers and reducing running processes and services.
