Satellite L740

A few weeks ago I started having a few problems:

-Computer lags for minutes at a time regardless of activity

-Speakers occasionally make deep, loud buzzing sound

-Computer has trouble playing games it used have no trouble with

-Computer has trouble playing games well within the recommended system parameters

-Computer occasionally crashes, displaying a blue background with white text, automatically restarting itself

Re: Satellite L740

Which L740 do you have? The model number should be on a label on the bottom.


Are you using any anti-virus?


Try using System Restore to restore a previous restore point from before this became an issue.
