    I was just writeing an email and all of a sudden the cpu went mad!

    NT4 sp6a, went into task manager shut down alota stuff but still the usage kept jumpin from 65% - 100%.
    I restarted the machine n appears fine now but its not the first time!

    Its a dell optiplex gx110, p3 800mhz so it really shouldn't be happening.

    I thought it might be someone runing something from my comp over the lan so i stoped shareing my hd but no change... confused.gif

    Anyone come accross this or know why it happens?

    p.s. antivirus software is updated regularly, so i douth its a virus...

    Could be your AV software scanning the H/D.
    In task manager go to processes and sort by cpu. Find out what process is hogging your resources.

    Outlook Express 5 used to do that all the time on me on NT4. I'd be reading away and then it would just grab 99% of the CPU time and stay there until I shut down the process. It seems fine on Win2k.

    Maybe some sort of caching thing? Is the NT4 version of Outlook (assuming there is a different on) more aggressive with resource hounding then the Win9x/Win2k versions?(again assuming there are differences)

    Is it workstation or server?

    What is the task taking up the memory? Open up task manager and sort by CPU.
