    Maxed out CPU

    I am running Win98SE on a Celeron 333 with 64MB RAM, and my CPU usage (as indicated by system monitor and Techfacts98) is constantly at 90%+. It's very noticeable that CPU intensive processes are exceptionally slow (as slow as I remember my 486 being). I have tried closing all applications, removing all services and running bare win98, but it doesn't seem to make any difference. Is it something about the way things are measured, or just that I have a slow old processor (but this is win98, not 2000 or ME or up)? I don't have any virus or worm that I can identify either.

    Any suggestions as to why this should be or what I can do about it would be much appreciated.

    Re: Maxed out CPU

    What AV software have you used? Ctrl+Alt+Del will show all the programs running (usually). Does anything look out of place or unnecessary? If not sure about anything, post the list. Don't touch systray or explorer; but ending things you don't think should be there (one at a time) may find the culprit.

    Re: Maxed out CPU

    Norton AV2001. I had already tried eliminating all suspects by ending tasks through task manager, with apparently no effect. I then stripped everything except systray from my startup, hklm run, hkcu run, hklm run services, leaving only systray and explorer in the task list.

    When I start system monitor under these conditions, the initial CPU usage is 3%, but as soon as I so much as move the mouse, this goes up to about 25% and stays there, if I then open a simple app (eg notepad), the usage goes to 75-95% and stays there. Sometimes it fluctuates by about 10%, and occasionally (for one reading) dips towards 0, but then always bounces back again.

    I don't understand how system monitor assess CPU usage, and maybe this is my problem, because it seems that an awful lot of nothing is using my CPU time - but only as soon as I start any app.

    BTW, I am running this on an IBM thinkpad 240, so do't know if that makes any difference.

    I guess my only thoughts are that either I have a very difficult to find nasty, or that a complete reinstall might help, althought that's an awful lot of hassle for very uncertain gain.

    Hi
    Grab another 64Kb of memory (at least) whilst it's still cheap. You'll notice a performance increase, though whether this will decrease CPU usage, I'm not sure.
    Install T-Clock to see both CPU and memory usage in the Systray.

    Re: Maxed out CPU

    Unfortunately IBM Thinkpads haven't heard that memories cheap - I'm looking at about 200US for another 64MB (max expansion) where I am (although that's a very long way from the centre of civilisation).

    Performance on the whole isn't an issue - except for CPU intensive tasks as mentioned above, which is why I'd like to understand what's going on.

    Is that the south african TClock or the japanese TClock?

    While we're on the subject of useful apps, is there anything that will do the equivalent for Win98SE that windows task manager does for win2k - ie list all processes together with their CPU usage. I've found plenty of process monitors, but none that show CPU usage for each process in real time.

    Thanks again

    See what you can find at Win9xME Task Manager and <A target="_blank" HREF=http://pages.infinit.net/bionic/>Bionic CPU Peeker</A> that may do what you want.

    Re: Maxed out CPU

    Unbelievable! It's the USB!

    Following MerC's suggestion, I used Tclock to continuously monitor CPU usage, and noticed that when I plugged in any USB device, the CPU usage returned to normal levels, and then sky rocketed again as soon as I unplugged it. If I disable USB in this profile, the CPU usage remains normal.

    There was an additional feature that I had forgotten about, which is when I move to battery power, the CPU clock speed halves, but this effect is nothing like the USB effect.

    I will see if I can get any joy out of IBM, but in the meantime if anyone knows enough about Win98SE USB implementation to be able to shed any light on this, I'd be very interested.

    <A target="_blank" HREF=http://www.crucial.com>http://www.crucial.com</A> quote 128Mb RAM for IBM Thinkpad 240 at $27.89, if bought online. Max system memory is 192Mb.

    MerC - I know what a T-Sip is, but what is this T-clock?

    Re: TClock

    Thanks again, Lord Leif. I have a couple of spots to use this tool on.

    Re: Maxed out CPU

    So what is a T-sip; or am I just ignorant? <img src=/S/shrug.gif border=0 alt=shrug width=39 height=15>

    Football rivalry:

    T-sip = tea sipper = Univ. of Texas student (city kid)
    vs
    Dum a** = Dumb Aggie = Texas A&M student (farmer)

    Re: Maxed out CPU

    I used to share a house with an agriculture student from Orkney. They (not just the ones from Orkney) get drunk, fight and break things. Is it the same in Texas?
