There are just a few issues I have now, everything else is working fine.
Standby and Hibernate work sporadically. Using the options on the Start Menu usually does not work at first. The computer will appear to do nothing. If I use the Dell keyboard shortcuts, I will usually have to press them twice, and with some hesitation it will standby/hibernate. After this, if I bring the computer out of Standby or Hibernate and then try to use the buttons on the Start Menu, it will work, and as fast as it normally should.
Normally, when it works properly, I will get the blue background "Logging off" or "Preparing to Standby/Hibernate". If after using the Start Menu options, and it does not work, I try to Log Off, I will get the NT login dialog box instead.
Closing the lid does not always make the computer go into standby, as it is set to do. It almost always worked before.
Media Center (the program) also crashes evey time I try to do more than just browse the settings menus. If I start playing videos or a DVD, then click the Home button, it will crash every time.
Since I installed Service Pack 3 immediately after installing Windows, I did not try any of these features since the restoration and before installing SP3.
Standby, Hibernate, and Media Center always worked perfectly fine before the restoration. Everything else about Windows and other programs seems fine. Because of that, I am not expecting a bad installation of Windows, McAfee, any other programs, or any or my startup items to be the cause of these things.
Have you heard of either of these problems being related to Service Pack 3? Could they be? Could removing SP3 fix these problems? Is it possible that removing SP3 could destabilize Windows or cause any other problems?
