A several times a week my screen just freezes and requires me to hold down the power button to shut it off and power it back on.  I could be typing, watching a webinar or the screensaver might be going and the computer just freezes.  I've had the machine for about 2.5 years.  I was hoping it might be software related maybe from the Lion upgrade or maybe a remnant of an app I had deleted a while back.  I wiped my hard drive and did a clean install of Lion.  I manually added back all apps and didn't use anything from Time Machine.  The drive isn't making any noises and isn't running hot.  Not sure what is could be?

 

Ideas?

    try an SMC reset but first try these:

    Before Resetting the SMC

    Try each of the following steps in this order before you reset the SMC.  Test the issue after completing each troubleshooting step to determine if the issue still occurs.

    1. Press Command + Option + Escape to force quit any application that is not responding.
    2. Put your Mac to sleep by choosing the Apple () menu from the upper-left menu bar and then choosing Sleep. Wake the computer after it has gone to sleep.
    3. Restart your Mac by by choosing the Apple () menu from the upper-left menu bar and then choosingRestart.
    4. Shut down your Mac by by choosing the Apple () menu from the upper-left menu bar and then choosing Shut Down.

    If your Mac appears to be running normally but isn't responding, force the computer to shut down by pressing and holding the power button for 10 seconds. Note: You will lose any unsaved work in any open applications.For Mac portables experiencing issues related to the MagSafe power adapter and/or battery, try:

    1. Unplug the MagSafe power adapter from the Mac and the wall power socket for several seconds.
    2. Shutdown the Mac. Physically remove and re-insert the battery (if it's removable) and startup the Mac.

    If the issue is still not resolved after following the troubleshooting items above, an SMC reset may be necessary.

     

     

     

    if you told us the model number of your machine I would be able to tell you which SMC reset to do. assuming you have one with a battery door that you can remove without unscrewing anything, then do this one:

     

    Resetting the System Management Controller (SMC)

    Resetting the SMC on Mac portables with a battery you can remove

    Note: Learn about removing the battery on MacBook and MacBook Pro.

    1. Shut down the computer.
    2. Disconnect the MagSafe power adapter from the computer, if it's connected.
    3. Remove the battery.
    4. Press and hold the power button for 5 seconds.
    5. Release the power button.
    6. Reconnect the battery and MagSafe power adapter.
    7. Press the power button to turn on the computer.

    then it must be one of the apps if you really did a clean install of Lion and have also done an SMC reset.

     

    have you also tried a PRAM reset?

    Let us know how the PRAM reset works out for you. Both the SMC and PRAM resets are generally harmless and will just reset everything that they are a part of, basically back to factory settings. This would mean, any changes to power handling or anything like that you did when you started using it will need to be checcked out and just changed to how you wanted it.

     

    For instance, and I don't think this could purtain to you, but I have my Energy Saver settings to better performance instead of better battery life. The SMC reset will reset this setting back to better battery life.

     

    But again, let us know how it goes.
