    It seems as though whenever I've used my notebook for over, say, 30 minutes, the CPU usage goes up to 40-50% even when I just browse the internet and the fans spin constantly. I check Task Manager, but it shows no process that is using that much CPU runtime. Anyone else experiencing this? Anyone know what's going on?

    In Vista, it can be one of many things:

    Disk indexing
    Scheduled defrag
    Schedule malware scan by Windows defender

    or

    Scheduled antivirus full scan

    I have problems with this in vista too. Sometimes when my machine boots up, both processors go to 100% usage and just stay there. Nothing is apparently running. I have no scheduled tasks that I know of, etc. It drives me nuts (and makes me angry with the computer). It comes and goes. One week it does it, the next week the cpu will hover 0-8% at idle. I wish I knew why.

    Some antiviruses do a quick scan on every boot. Symantec AV does it in XP.

    All those tasks that I mentioned are enabled BY DEFAULT. You do not need to know about it, it comes with the installation of the OS and software. So, please check if those are not the culprits.

    If you upgraded to 64bit os some of the drivers do cause this issue. We ran into it before. Remove defender if it is installed.!

    If you need to remove defender, install an alternative for malware and adware scanning.

    E.B.E, just wondering about that antivirus thing. Are you talking about nortons antivirus 2007? Does that do a quick scan every time the os loads? i have it installed on my xp and after that its been such a pain turning the pc on since it take soooooooo damn long for the pc to be responsive after powering it on.

    I am sure that some Symantec products do a quickscan on boot up. To check, start Task Manager as soon as you are logged on and look for a DoScan process or something similar.

    To avoid this, you can use hibernation instead of shutdown and restart.

    BUT: I strongly recommend NOT using Norton AV, it is a resource hog and known to cause significant slow downs. Use a lightweight alternative. Good options are:
    Paid: NOD
    Free: AVG

    It runs at a constant 40-50% load for hours if I don't restart it with no HDD access.

    Hours doesn't seem right.

    What is the process that is taking up CPU?

    Well, that's what I get for talking about my problem. Mine resurfaced today. Usage between 60-90% even while nothing is going on. Sidebar and task manager report different usages. Problem comes from system and 'eshell' mainly. Sweet.

    The list of processes in task manager doesn't show anything that's using more than say 1 or 2 percent CPU resources. 98% are in like system idle.

    That is a contradiction. How can it take 50% of the CPU for hours if 98% of the CPU is idle?!?

    "Mine resurfaced today. Usage between 60-90% even while nothing is going on. Sidebar and task manager report different usages. Problem comes from system and 'eshell' mainly. Sweet."

    Trust the task manager, not the sidebar. With the system you can't do anything (besides disabling indexing, defragmentation, defender scans and the like) but try to find out what eshell is. Maybe it's some poorly coded applications or even malware (hopefully not).

    My problem seems to be a constant flux up and down of resources so quickly, it tricks the sidebar. Either way, when I go into task manager, it shows most (70% +) resources free. I found that if I hit 'show processes from all users' that there are some things NOT showing up in MY task manager using up resources. However, I'm actually inclined to believe the sidebar in this case for a few reasons. Heat, fan noise and the system responsiveness.

    This comes and goes for me. It seems to have gone again. It sticks around for a couple days, drive me nuts then leaves. HOWEVER, I am still having a MAJOR problem with the Expresscard/54 tv tuner I have. If I start the system with it, it seems to be ok. If I plop it in after the system has been up for a while, one of my cores jumps right to 95%+ and just stays there. Even if I am idling and not using the tuner at all. I'm a bit baffled by this because quite often, I can't really track down the process causing it!!! I know that sounds crazy, but the system resources just don't seem to add up, but again, the sidebar seems to be telling the truth based on how the system responds.

    Seems like a driver issue...

    I'm not trusting the sidebar, in fact, i don't use sidebar. On one tab it says 98% in system idle process in another tab it says 50% usage on the graph, in the same task manager window. the fans are always spinning on mid-high, and the notebook's noticeably hot. it's definately under load.
