My cpu usage is spiking 100% or running up there pretty constantly. This is a pretty new laptop which I got in March.
Asus G60Vx Intel Core2 Duo
2.13 GHz
RAM:4.00 GB

I'm not sure what is happening that is causing this. For example right now, I just restarted the laptop and I have my msn messenger and firefox on and it's jumping around from 37% to 100%. I don't see that's going on in other processes that might be the cause of this. This has been going on for a few months now and I'm at a loss. My virus scans find nothing- I use Trend Micro and just tried Malwarebytes and that found nothing as well. Any suggestions?

Your screenshots show CPU usage by Firefox and Messenger at 0%, so I'm not sure, where you see that high CPU usage.

At the bottom of the Task Manager window, there will be a button that says Show processes from all users. Clicking this button will allow you to see all the processes that are running on your computer (default view of the TM in Windows 7 doesn't show everything), and narrow down which one is eating your CPU. :huh:

At the bottom of the TaskManager window, it shows the percentage of CPU being utilized like CPU:18%. The processes like winlogon.exe should show SYSTEM as user but your snapshots are showing blank. The System Idle Process is absent from the snapshots which could have shed light on your problem.

EDIT : Do what keyboardNinja/Broni said. I forgot what UAC can do to simple programs like Task Manager.

...or...

Download Process Explorer: http://technet.microsoft.com/en-us/sysinternals/bb896653.aspx
Unzip ProcessExplorer.zip, and double click on procexp.exe to run the program.
Click on View > Select Colunms.
In addition to already pre-selected options, make sure, the Command Line is selected, and press OK.
Go File>Save As, and save the report as Procexp.txt.
Attach the file to your next reply.

Romeo, cantcme99 made legit screenshots...but they are without Show processes from all users being checked, as I previously mentioned. Without that checked, winlogon doesn't show a user (same on my computer), and System Idle Process doesn't even show up (it only shows the processes being used by the user, in this case Janna). :huh:

Note: System Idle Process should be using most of the CPU. All the unused percentage goes to the idle process.

You are right keyboardNinja :huh:

I keep my UAC turned off, so I see all processes by default. cantcme99 has UAC turned on as most people do. I am insane.

To clarify, after un-checking Show all (after having clicked it), it does show SYSTEM.

BUT, if you never clicked Show all, then it doesn't show a name.

I will demonstrate with screenshots. :inlove:

I have some screen shots of process explorer. Today it seems to be idling in the normal range, but shoots way up and stays up if I'm doing anything. As I type this it's bouncing around between 12% and 58%. I'm not convinced it's doing better though. If I run a game it stays on 90%-100% and this computer should be able to handle games since it's a gaming laptop. I see there are a bunch of svchost.exe's that show up and I think that's not good? Thanks for your help everyone!

It looks like TrendMicro is killing your computer.
Do you have it installed?

I do have Trend installed. Here I thought it was one of the better anti-virus programs out there too. I wasn't having this problem until the end of the summer though and I've had Trend always. Would it be something that could just have started randomly?

It may be some of Trend's recent updates.

Try to reinstall it.

If you reinstall Trend, it will just update itself again back to the current version they are pushing through auto-updates.

It can't hurt to try, I'm just saying...don't be shocked if nothing changes.

Personally, I would just find a better AV.
