How can I fix a sudden drop in Windows Vista performance?

Srikanth February 1, 2010

The OS is Vista. Since about 10 days it is so slow. It takes ages for a program or IE to start.

What could be the reason? Any help is appreciated.

    Thank you so much. Actually the problem turned out to be some virus. I have QuickHeal AV and once I updated it to 2010 version and ran a scan, the pc started running (streaking along, in fact) like it is brand new.
    Thanks for the step by step instructions for system restore. I'll save that so that I don't forget it again.

    Thanks for the help. I tried the power options but still no improvement. Can you walk me through the system restore route please? I am not sure how it is done.

      Instructions for System Restore:

      1- Right click on My Computer icon
      2- Go to Properties option
      3- select System protection tab (wait for the the 'searching' to complete)
      4- click on the System Restore button
      5- Choose a restore point before the date problem began
      6- complete the System Restore

      The Sysetm Restore won't erase your files or personal settings.

    Your question is way too broad, there are tons of things that might have caused the slow down. That being said, i actually do have a couple of ideas:

    1. Check the power options and make sure the setting is set at maximum performance.

    2. Did you try the system restore to bring the system to an earlier state?
