    Hi - first post here,

    My laptop (specs below) has been using about 40-50% physical memory continually for a while now, causing the fans to work overtime (?) and the system response time to slow. This occurs even when CPU usage is 0-5%

    I've read forums here and elsewhere on this and tried a number of things, but nothing I've done so far has had much effect:
    - used MSCONFIG to reduce the number of startup items to 5-6
    - Ran disk clean-up to free-up space (+ laptop runs defragmentation weekly)
    - Uninstalled unwanted programs using Control Panel -> Add/Remove...
    - checked Task Manager -> Resource Monitor -> Physical Memory...and there is not enough committed memory displayed to take up 2GB RAM
    - Ran http://www.uniblue.com/software/speedupmypc/, which helped on the margin with some things, but not with the physical memory
    - Ran "chkdsk /f", but little change afterwards
    - Full scans by fully updated versions of AdAware & Norton Antivirus show no malware

    Possible reasons:
    - I'm still running about 65 processes (40 mine, 25 system), although most seem very very small on memory usage
    - Laptop tells me 290GB of my 320GB hardrive is full. I have a large music collection on there, but I don't understand this - here's what I have counted:
    - Music files: 130GB
    - Games: 17GB
    - Photos/Videos: 20GB
    - Other Programs: <5GB
    - Other My Docs: <5GB
    - So even accounting for other held back hard disk space, I don't see how this gets too far above 200GB
    - Physical memory runs at 40% even when not using My Files or Games - and shoots up when running things like Crysis or Football Manager (which run fine despite this)


    The laptop heats up very quickly and fans get loud even though it's almost always on a table - although loud fans seem to be a "feature" my laptop anyway, common occurence for others. Any help would be greatly appreciated as I'm not entirely sure where to go from here.

    Thank you in advance

    But I haven't by any means been running it hard all the time over that period.

    Programs like Crysis would cause the cpu to heat up and then get the fans going full tilt - thats normal. Also Vista is designed to use up most of your ram, by pre-loading stuff it thinks you will use, and then unloading them as you double click other programs.

    Thanks for the reply.

    I understand that Crysis and FM 2009 are pretty hard going on the CPU - but when these are not running, are you saying that Vista sets aside RAM that it thinks I may use? So it's using 40-50% all of the time in anticipation of what I might do? Is this kind of scale normal, seems high?

    I'm a bit concerned about both the take-up of memory when nothing major is running, and the fact that I can't account for all of the hard-disk space that's gone. Do you know a good way of finding out a breakdown of the latter by something like name/folder/location/etc.?

    Relieved that the antivirus software hasn't found any malware, but any suggestions about how I might be able to figure out what's going on would be really helpful.

    Thanks again.

    Thanks Lunarlander, that's a great little program. Found stuff I'd forgotten I had on there.

    It all added up to 246GB according to TreeSize. But Properties on my C: tells me I have 291GB used space. 45GB is a little much I would think for held back space. Ever come across this before?

    System Restore also uses space, don't know if that is reported by treesize.
