High cpu use while computer is idle

Bummer, having a corresponding IO spike would have made things easier to track down.

AVG antivirus used to load their signature files into the System process. This caused a lot of IO traffic to/from that process. Which is why I asked about the IO activity.

Does this CPU activity show up while in the safe mode? (just the safe mode, not safe mode with networking or any of the other safe mode variants)

In safe mode, the cpu activity will stay at zero.

I had a similar issue, mine was an audio driver that somehow didnt install correctly. Once i found out i uninstalled. Ran CCleaner and Driver Fusion to remove all traces of it. And reinstall BAM problem solved.

So what drivers have you updated after fresh installation?

All of them. I've also tried disabling/uninstalling the audio device, but I'll take another look at that. I may also take a look at just installing the drivers that came with the mobo to see if the problem is present there.

edit: Turns out it's the printer port(LPT1). I just started disabling devices and it turned out to be that one. Since I don't need that I'll just leave it disabled.

That was easy...

Drivers do my head in. I cant install one now without using safe mode first and cleaning any old traces lol.

Install it properly and it should be fine.

Assuming that it is the driver anyway.

Drivers have sure used up a lot of my time too. I'm just putting the parallel port and the two com ports on the disabled list until further notice. I can't imagine why I'd ever need them.

Thanks to everyone for your help.

Atom, try this: In the Start box type resmon / Enter. The Resource Monitor will open, follow the numbers in the snip to find specific CPU processes in use. Note it may have two scroll bars to see the bottom bars, this is a composite image.

I use Process Explorer for this, but was unable to determine anything from it. Did you see my previous post. I'm marking this solved.
