    I also experienced this kind of temperory freezing with my frend's pc also. he also has installed ubuntu 9.04. I hope there's no bug in this version.
    I have heard more than a few people complaining about this newest release, some even plan on reverting back to a previous release until this mess gets sorted out. Problems with Wifi, Printing and a few other things I'm sure.
    Did you see anything useful in /var/log/messages? You can use grep to try and sort it a little bit, because it's a huge file.
    Code:
    cat /var/log/messages |grep error
    cat /var/log/messages |grep fail
    cat /var/log/messages |grep panic

    Code:
    May 24 07:55:01 krishna kernel: [47650.986605] compiz.real[3296]: segfault at 28d85e ip 08055c0c sp bfb4c720 error 4 in compiz.real[8048000+34000]

    A Compiz error it seems.
    I guess you could try shutting off the Desktop effects and see if this helps any.

    After disabling visual effects for desktop, I couldnt find any change in the performance. My computer still keeps freezing.
    Now "cat /var/log/messages |grep error" displays the following errors:
    Code:

    I would also like to know if there are any chances of getting affected with viruses. I believe that there are no viruses for linux.

    I dont want to reinstall Ubuntu again. I have customized it a lot.. Is there any possibility that i can run Ubuntu without any issue?
